Black Clover Season 4: The Season That Ended Too Soon and Set Up Everything

Sixteen episodes. That is all Season 4 of Black Clover got. Sixteen episodes — the shortest season of the entire run — covering what might be the most narratively consequential stretch of the whole 170-episode journey. In those sixteen episodes, the show introduces a character who redefines the Black Bulls entirely, delivers one of the most emotionally significant power-up sequences in the franchise, reveals the truth about Asta's origins in a finale that left the entire fanbase screaming at their screens, and then ends on a cliffhanger so brutal that fans spent four years waiting to see what came next.

Season 4 is short. Season 4 is impactful. And Season 4 is the runway for everything the new Black Clover anime is going to do when it premieres in 2026. If you want to understand where the story is going and why the announcement of a continuation generated the reaction it did, this is the season you need to understand completely.

Let us go through every detail.

Introduction — Production Details

Black Clover Season 4 was directed by Ayataka Tanemura — a change from the previous three seasons, which were all directed by Tatsuya Yoshihara. Tanemura had been a significant episode director throughout the series, so the transition was handled by someone with deep familiarity with the show's visual language and tone. The season was produced by Studio Pierrot and aired on TV Tokyo in Japan from December 8, 2020 to March 30, 2021, covering 16 episodes — episodes 155 through 170 of the overall series.

Both Crunchyroll and Funimation licensed the season for international release. Crunchyroll simulcast the episodes, while Funimation produced the English dub, which aired on Adult Swim's Toonami programming block from June 20 to October 10, 2021.

The season adapts the manga in a specific and important way. The first three episodes — 155, 156, and 157 — are anime-canon original content supervised by Yūki Tabata, covering training sequences during the final portion of the six-month Heart Kingdom stay. Starting from episode 158, the season adapts the 24th volume of the manga directly, covering the Heart Kingdom Joint Struggle arc and the beginning of the Spade Kingdom Raid arc through chapter 266.

The season uses two opening themes and two ending themes. The first three episodes continue with "Everlasting Shine" by Tomorrow X Together and "A Walk" by Gakuto Kajiwara — carried over from Season 3's final stretch. From episodes 158 to 170, the opening theme is "Grandeur" by Snow Man and the ending theme is "Beautiful" by Treasure. "Grandeur" is widely considered among the best openings in the entire series — its grand, sweeping energy matches the escalating scale of the Spade Kingdom threat perfectly.

In Japan, the season's home media was released in a single volume — the sixteenth volume of the Avex Pictures Blu-ray release — on June 25, 2021. In February 2021, before the season had even finished airing, Pierrot announced that episode 170 would be the final episode of the television series, with a film announcement to follow. That film — Black Clover: Sword of the Wizard King — was eventually released on Netflix on June 16, 2023. And at Anime Expo in July 2025, a new Black Clover anime season was announced, produced by Pierrot and set to premiere in 2026.

Where We Left Off — Season 3's Cliffhanger

Season 3 ended with the Dark Triad executing their coordinated assault on the Clover Kingdom and the Heart Kingdom simultaneously. Zenon Zogratis attacked the Golden Dawn headquarters, annihilating half the squad and capturing William Vangeance. Dante Zogratis attacked the Black Bulls directly, seeking Yami Sukehiro. Despite a brutal fight — Asta managed to land a blow on Dante that left the Dark Triad member stunned for the first time — Dante escaped with Yami as his prisoner. The Dark Triad needs Yami's Dark Magic and Vangeance's World Tree Magic to activate the Tree of Qliphoth, a ritual that would open the gates of the underworld and allow every devil within it to pour into the human world.

The 203rd Mage Battalion — sorry, wrong show — the Magic Knights were left reeling. Their strongest captain was gone. Half the Golden Dawn was dead. The Heart Kingdom was under attack from Vanica Zogratis and her cursed disciples. And a new character emerged from the shadows in the season's final moments, restraining Asta before he could charge off alone to rescue Yami: a Black Bulls member nobody had ever seen before, introducing himself as the squad's vice-captain.

Season 4 opens exactly there.

Story — Every Episode, Every Detail

Episodes 155–157: Anime-Canon Training Finale

The first three episodes of Season 4 are the final stretch of the Tabata-supervised anime-canon training content that began in Season 3's episode 130. We are still in the Heart Kingdom, still in the six-month training period, and the show uses these three episodes to show both the remarkable progress characters have made and the significant gaps that remain.

Episode 155 — "Five Spirit Guardians" — assembles the full picture of how far each Magic Knight has come under the Heart Kingdom's training program. The Spirit Guardians — the elemental mages who train the Clover Knights — report to Princess Lolopechka. Rill and Charmy have taken naturally to Mana Words, the Heart Kingdom's technique of imbuing spells with layered instructions that make them more precise and more powerful. Noelle and Secre have made the most dramatic progress. Leopold and Finral are both being held back by internal issues rather than lack of talent — Leopold feels perpetually in the shadow of his famous siblings Fuegoleon and Mereoleona, while Finral's avoidance of combat use of his spatial magic limits his growth in a situation that demands combat.

A subplot that carries real weight in this episode: a group of rebel Spade Kingdom mages attempts to cross into the Clover Kingdom through the strong magic region, carrying intelligence about the Spade army. They are attacked by Spade soldiers who transfer their remaining magic to their leader, Ralph, so he can escape. Ralph collapses near Hage Church, calling out for "Prince Yuno." The mystery of this moment is planted deliberately — what does it mean that someone from the Spade Kingdom is looking for Yuno?

Episode 156 — "Awakening Power" — focuses on the training's most difficult cases. Leopold confesses to his trainer Floga that he feels inferior to Mereoleona and Fuegoleon, and it is keeping him from committing fully to growth. This is a rare moment of emotional honesty from a character who usually projects pure confidence, and it lands genuinely. Yami, meanwhile, trains with Mereoleona at a volcanic location — he wants to master the Mana Zone technique that he used instinctively against Zagred in Season 3. What he achieves is significant: he develops the ability to maneuver in mid-air using Mana Zone the way Mereoleona does, and unlocks a new spell — Dark Cloaked Black Hole — that can swallow an opponent's magic without being able to be counterattacked the same way. Yami's growth here, quiet and off-screen in terms of the main narrative, will pay dividends in the battles to come.

Asta's training situation in these episodes is the most thematically interesting. He cannot use Mana Words the way other mages can — Mana Words require sensing and manipulating the flow of magical energy, which Asta has none of. Gaja, who trains him, keeps defeating him handily in sparring matches. But in episode 156, something shifts. Asta realizes that his Demon-Dweller Sword can borrow magical energy from allies — and that by using this in conjunction with his own ki-sensing, he can find workarounds that no one else could devise. He lands his first blow on Gaja. It is not a victory. But it is evidence that Asta's growth has a ceiling nobody has correctly calculated yet.

More importantly in episode 156: Gaja catches a brief manifestation of Liebe — the devil within Asta's grimoire — protecting Asta from a strike during sparring. Gaja says nothing about it to anyone except to himself, and he decides he must push Asta to his absolute limit to develop those powers further. Within Asta's grimoire, Liebe watches and thinks: events are getting interesting. The show is setting the table for what Season 4 will deliver.

Episode 157 — "Four-Leaf Clover" — is a framing episode structured around Gaja asking Asta to explain his story from the beginning. Asta recounts everything: being found at the church in Hage, growing up with Yuno, failing to receive a grimoire while Yuno got his four-leaf clover, the moment Licht's old grimoire flew to him as a five-leaf clover, joining the Black Bulls, every key battle from the dungeon to the Underwater Temple to the Witches' Forest. It is both a recap and a character moment — the act of telling his own story allows Asta to locate himself within it, to understand where he has been and what it means.

The episode ends with a tonal shift. Candelo — a Spade Kingdom mechanized citadel powered by siphoning magical energy from enslaved Spade commoners — crosses into the border region. Asta, who has been growing continuously through the training and can now fly astride his Demon-Slayer Sword, flies out to intercept it alone. He is enraged by what he sees: Spade knights draining prisoners of their life force. He absorbs the commander's poison magic with his Demon-Destroyer Sword and cuts the citadel in half in a single blow. The prisoners are freed. The commander, who is also a devil vessel, is defeated in one strike. Asta flies back.

This moment functions as the show's announcement that the training is over. Asta is not who he was at the start of Season 3. The boy who lost every sparring match with Gaja just a few episodes ago is now the person who halves a mechanized fortress by himself without breaking a sweat. The six months meant something.

Ralph finally reaches the Hage church and collapses before Father Orsi. He calls out for Prince Yuno. Yuno receives word and travels to Hage — and learns something that reframes everything about his identity.

Episodes 158–163: The Heart Kingdom Joint Struggle Arc

Episode 158 — "Opening of Doom" — begins the manga-faithful adaptation and the season's main conflicts simultaneously. The Dark Triad makes their move. The Spade Kingdom army marches toward both the Clover Kingdom and the Heart Kingdom simultaneously, crossing the strong magic borders using the mechanized citadel Candelo as cover. And Yuno, having heard Ralph's revelation at the church, is trying to process information about himself that changes everything about who he thought he was.

Ralph reveals the truth through visions of Yuno's past: Yuno was born the first son of King Royce and Queen Ciel of the Spade Kingdom — House Grinberryall, the royal family that ruled before the Zogratis siblings seized power. His family's rule was peaceful. Then the three Zogratis siblings — Dante, Vanica, and Zenon — gained devil powers and violently took the kingdom by force, slaughtering the royal family. Yuno was an infant. Ralph's father smuggled him out through the strong magic region, left him at the orphanage in Hage, and then collapsed the cliff behind them to kill the pursuing Spade soldiers, dying in the process. Yuno's necklace — the one he has worn since childhood — is a keepsake from his royal parents.

Yuno, still processing this, receives emergency word that the Golden Dawn headquarters is under attack. He does not have time to absorb the revelation. He runs.

Episode 159 — "Zenon's Power" — covers the assault on Golden Dawn headquarters. Zenon Zogratis arrives personally, having sent his disciples ahead. His disciples are Zero Stage mages — people enhanced with devil power by the Dark Triad, criminals and killers whose natural magic has been amplified to the point of overwhelming trained Magic Knights. Yuno fights through them. He dispatches one disciple named Gaderois using his Zephyr Slash — a wind sword technique that strips through enhanced stone armor. He and Klaus together destroy a second disciple named Foyal, whose mist magic normally makes him intangible.

Then Zenon appears. He has already captured Vangeance. He looks at Yuno — who just demonstrated more raw ability than any other member of the Golden Dawn — and decides to show Yuno what real power looks like. He activates his devil power. Yuno throws everything he has at him. It does nothing. Zenon is completely untouched. He impales Klaus and Letoile with bone spears — not killing them, just removing them as factors — and departs with Vangeance. Ralph arrives at the aftermath and finds Yuno barely alive. Vangeance's World Tree Magic sprouts through the rubble to begin healing the survivors — an act of magical compassion from a man who is unconscious and captive, spending the last of his reserves to save his squad. Half the Golden Dawn is dead. Yuno screams. He blames himself.

Episodes 160 through 163 cover the simultaneous assault on the Heart Kingdom. Lolopechka senses six enemies entering the kingdom — Vanica Zogratis and her five cursed disciples. This is what she has been dreading. Her curse, the one Megicula placed on her, will activate at some point during this encounter. She knows it. She fights anyway.

The Heart Kingdom battles are remarkable for how effectively they use the training that was established in the preceding episodes. Every character who trained in the Heart Kingdom gets a meaningful battle sequence that directly reflects what they developed. Luck, trained by the earth Spirit Guardian Gaja in natural lightning, faces Svenkin Gatard — a Dark Disciple who can manipulate his own body to be perfectly resistant to any magic type, including lightning. Luck's regular attacks are completely ineffective. So he applies what he learned from Gaja: natural mana, generated from his body itself rather than from his grimoire, can bypass Svenkin's defenses. He transforms himself into a living lightning bolt and blasts through Svenkin's chest. It is one of the most technically satisfying character victories in the season.

Leopold, who struggled with inferiority throughout his training, faces Sivoir Snyle — a disciple who uses hundreds of magical eyes to monitor the entire battlefield and snipe targets from maximum range. Leopold cannot get close without being hit. So he takes the hits deliberately, enduring the damage while crafting a massive Mana Words circle around the entire area, then calls down a volcanic eruption that Sivoir cannot see coming because the attack originates from below rather than from Leopold himself. The inferiority complex that was holding him back becomes the thing that makes his approach work — he fights like someone who cannot afford to make mistakes, which is exactly the mindset the battle required.

Charmy, who spent most of her training eating the Heart Kingdom's fruit, has a battle against Halbet Chevour — a disciple who burns Charmy's food sources and advocates for minimalist nutrition with the fervor of an ideologue. The show has been building toward Charmy's true nature since Season 1 — hints and fragments suggesting she is more than her comedic surface. When Halbet destroys the food, Charmy transforms. Her adult form appears — a calm, composed young woman who looks nothing like her usual chibi self. Her sheep chef becomes her gluttonous wolf. She eats Halbet's magic entirely, consuming it to nothing, and then beats Halbet with casual brutality. Charmy's true nature is not comedy. It is something else, something the show has been carefully not naming yet.

Vanica's arrival at Lolopechka's throne room is the conflict's emotional core. Vanica is the one who cursed Lolopechka. Their confrontation is deeply personal — the queen facing the person who has been killing her slowly for years. Lolopechka reveals a technique of breathtaking sophistication: combining Mana Zone with Mana Words, she halves Vanica's magical power output while simultaneously doubling Noelle's. This unlocks Noelle's next evolution: Valkyrie Armor — Mermaid Form, a water armor that allows her to move with fluid, underwater-like agility even in air. She attacks Vanica with the full force of her enhanced armor.

But Vanica has a trump card the heroes did not account for: she cursed each of her disciples with immortality. None of them can die unless Vanica herself dies first. Every disciple who was defeated gets back up. All five attack simultaneously. The Spirit Guardians are overwhelmed. The people who were defending the kingdom are now in a losing battle against opponents they cannot permanently defeat.

Episodes 164–167: Black Bulls vs. Dante, The Capture of Yami

These four episodes cover the simultaneous Black Bulls crisis and are the emotional centerpiece of Season 4.

Dante Zogratis — who was defeated and seemingly driven off at the end of Season 3 by Asta — has returned to the Black Bulls' base, and this time he has calculated for Asta's intervention. He uses gravity magic to levitate the Black Bulls' entire base — their giant, sentient, shape-shifting headquarters — and starts pulling it apart piece by piece. The Black Bulls inside scramble to respond.

Episode 165 — "Dante vs. The Black Bull's Captain" — is where the season fully delivers on the Dark Triad as a threat level above anything previously established. Dante's devil, Lucifero, is the King of Devils — the highest-ranking devil in the underworld. When Dante activates his devil power at increasing percentages, the results are catastrophic. He generates black holes that warp reality in his immediate vicinity, causing every attack to miss. He regenerates from any damage. He is, by the standards of every battle scale established in the previous three seasons, several levels above anyone the heroes have fought before.

Dante taunts the Black Bulls philosophically while destroying them. He argues that humans are inherently evil — that the darkness in human nature is not something to be overcome but to be celebrated. Asta, furious, disagrees with maximum volume and minimum patience. While Dante finds Asta amusing — specifically because Asta is devil-touched like Dante but refuses the implications — he is not taking him seriously. Not yet.

Then Asta slashes his face. It is not a decisive blow. But it is the first time in this fight that Dante has been marked. Dante, who was utterly bored by the entirety of human experience before this war began, is genuinely surprised. He looks at the cut on his face with something approaching interest. Lucifero, from within Dante's soul, notes that Asta's devil must be low-ranking — otherwise the hit would not have been possible. He is wrong. He just does not know it yet.

Episode 166 brings the season's most significant backstory delivery: Grey's origin. Grey is one of the Black Bulls' most consistently overlooked members — her transformation magic has always seemed underwhelming compared to the dramatic powers of her squadmates. The episode reveals who she was before the Black Bulls: a girl abused by her stepmother and stepsisters for not being beautiful enough. After receiving her grimoire, she used her transformation magic to make herself appear beautiful — which triggered jealousy and violence from her stepsisters. She ran. She was nearly killed by bandits. She was saved by Gauche, who told her she needed to find her own resolve. She assumed the giant form she uses as a defense mechanism and eventually found her way to the Black Bulls.

In this episode, Dante incapacitates Asta and moves toward Vanessa and Grey, informing them he wants them as mistresses — he has been collecting people he finds aesthetically or magically interesting throughout the war. Grey, watching Gauche dying from Dante's attack, does something she has never done before: she uses her transformation magic not to disguise something, but to change its fundamental nature. She transforms Gauche's wound — an injury — into healed flesh. It is an entirely new application of her power, and it suggests that her magic is vastly more powerful than anyone understood. Gauche lives.

Finral arrives with Yami. And Yami versus Dante is everything Season 4 was building toward as a spectacle.

Yami fights Dante at maximum capacity. He demonstrates his new spell — Dark Cloaked Black Hole — which generates gravitational fields that can resist Dante's own gravity magic and absorb his attacks. He slashes Dante's chest with a dark magic blade. Dante is ecstatic. For the first time in years, he is genuinely enjoying himself. He explains the stakes: he needs Yami specifically because Yami's Dark Magic, which can slash through dimensional barriers, is required to cut open the path to the underworld for the Tree of Qliphoth ritual. Yami's response is to keep cutting him.

The battle in the Heart Kingdom reaches its climax simultaneously in episode 167. Noelle in Mermaid Form and Lolopechka with Undine manage to push Vanica to her limit — but Vanica, rather than being defeated, reveals her true form. She releases Megicula's power at a higher percentage, and the curse on Lolopechka activates fully. Lolopechka cannot fight. Her curse is consuming her from within. At the moment of her greatest need, the person who was supposed to be able to stop Megicula is the curse's victim.

Vanica captures Lolopechka. She sets off an explosion in the Heart Kingdom powerful enough to level everything in range. Noelle, Mimosa, and the others are caught in the explosion. They survive — barely — and wake up in a forest beyond the Heart Kingdom, helped by figures they do not immediately recognize. The Heart Kingdom's spiritual population, the elves who settled there after the Elf Reincarnation Arc's resolution, have found them. The Heart Kingdom has fallen. Lolopechka is captured.

In the Clover Kingdom, Dante escapes. He cannot be stopped. He takes Yami by force, using his gravity magic to immobilize the captain while his disciples restrain him. Asta, badly injured and nearly unconscious, watches. He tries to get up. He cannot. Dante smiles at him — genuinely pleased by the experience, genuinely looking forward to the next encounter — and leaves. Yami, being dragged away, throws his katana to Asta. Not out of sentimentality. As a practical gift — Asta can use it. Yami is telling him: I am not dead. I am captured. Come get me.

The katana lands in Asta's hand. The Black Bulls' captain is gone. Asta holds the sword and makes a promise.

Episodes 168–170: Nacht, Liebe, and the Series Finale

Episode 168 — "Beginning of Counterattack / Reception of Help" — is where the season's most consequential new character finally steps fully into the light.

The Magic Knight captains convene an emergency meeting. The Golden Dawn has been decimated. The Heart Kingdom has fallen. Yami and Vangeance are prisoners. The Tree of Qliphoth ritual is beginning, and if it is completed, every devil in the underworld will have access to the human world. The timeline is desperate. There are no good options.

Into this meeting walks a man in a Black Bulls robe who nobody at the table recognizes. He has long black hair, shadow magic, and the demeanor of someone who has been thinking about this problem for much longer than anyone else in the room. He introduces himself: Nacht Faust, vice-captain of the Black Bulls. He has been undercover in the Spade Kingdom for years, gathering intelligence on the Dark Triad and their ritual. The captains were not aware of him because Yami never disclosed he had named a vice-captain — and Nacht only visited the Black Bulls' headquarters once before going undercover.

Nacht is everything the Black Bulls are not and everything the show needed at this moment. He is cold, precise, contemptuous of the Magic Knight institution's complacency, and absolutely ruthless in his strategic thinking. He knows the Spade Kingdom's castle layout. He knows the ritual's requirements and its timeline. He knows exactly how much time they have and exactly what needs to happen. He has a plan. He shares it with appropriate disdain for the people who let things get this bad.

He is also a devil host — he has bound four devils to himself through the forbidden Devil-Binding Ritual. Each devil represents a different aspect of his power and personality. He uses shadow magic as his primary ability and can merge with each devil to enhance that magic in specific ways. His control of four separate devil contracts, maintained simultaneously, is a feat that should be impossible by the conventional understanding of devil binding — it speaks to both how desperate and how disciplined Nacht is.

His backstory, revealed through the season's remaining episodes: he was born into the Faust family — an old noble house that practiced forbidden magic. He had a twin brother, Morgen, who was everything Nacht was not — genuinely good, genuinely kind, a knight who served with sincere faith in the things Nacht had long since abandoned. Nacht's reckless pursuit of devil-binding power killed Morgen. The devil-binding ritual that Nacht performed consumed Morgen in the process. Nacht has spent years since then in a state of productive self-destruction: using the power that killed his brother to fight the things he believes deserve to be destroyed, accepting that he is not someone who deserves to be saved.

He hates the Black Bulls — finds them undisciplined, chaotic, morally inconsistent. He tells them this directly. Then he tells them to get stronger if they want to save Yami. And he goes to find Asta.

Episode 169 covers the Devil-Binding Ritual between Asta and Liebe — one of the most carefully constructed and thematically resonant sequences in the entire 170-episode run.

Nacht takes Asta to the abandoned estate of the Faust family — the same location where his own devil binding happened, where Morgen died. He drops them into a secret chamber beneath the estate. He explains the ritual: Asta must fight his devil and win. If Asta wins, he can form a contract of total dominance — the devil becomes his servant, bound by whatever terms the host dictates. If Asta loses, the devil takes his body and Nacht will kill the resulting monster.

Nacht summons Liebe. Asta's right arm vanishes — the arm that Liebe's anti-magic has been channeled through — and Liebe takes physical form for the first time outside of Asta's black form. He is small, white-haired, covered in black markings, with wings and horns and a tail. He looks genuinely demonic. He is also, immediately, hostile — he grabs the Demon-Slayer Sword from the grimoire and swings it at Asta.

Asta does not fight back. He thanks Liebe for his help during all their previous battles.

Nacht is baffled. Liebe is furious. Liebe swings at Asta repeatedly, destroying the chamber's architecture. Nacht tells Asta flatly that the devil will kill him. Asta says he can sense the devil's ki, and it does not have killing intent. Liebe agrees with Nacht that all devils are evil — but Asta's words, and Asta's face, trigger something in Liebe. Something he does not want to feel.

Liebe fights because he has to process his anger somewhere. He summons all the swords from the grimoire simultaneously. Asta picks up Yami's katana — the sword his captain left him — and fights back using the swordsmanship he has absorbed from every battle. He copies Yami's movements. He copies every swordsman he has ever faced. He overwhelms Liebe in close-quarters combat and strikes the devil's forehead. Victory. The ritual completion. A collar begins to appear around Liebe's neck.

And Asta tells Nacht he does not want to subjugate Liebe. He wants to make a contract of equals. He wants Liebe to be his friend.

Nacht is stunned. Liebe is stunned. Nacht explains that there is no practical benefit to a contract of equals — the devil has no obligation to comply, there is no guaranteed mechanism of control. Asta says he could sense through their ki that Liebe is different from Zagred, different from the other devils they have encountered. He is not evil by nature. He is angry. There is a difference.

Liebe remembers Richita. Asta looks like her. Speaks with the same quality of certainty, the same kind of genuine care. Liebe falls backward. The collar dissolves. Asta holds out his hand and asks for the devil's name. Liebe — who has not been called by his name in a long time — introduces himself. They shake hands. Matching marks appear on their left wrists. Asta's right arm returns.

Nacht, who called the contract "unprecedented and foolish," smiles. It is one of the few genuine smiles he has in the entire season, and Asta is surprised by it. Nacht then merges with his own devil Gimodelo and attacks them both — training continues immediately. There is no time for sentiment.

Episode 170 — "The Faraway Future" — is the series finale. And it is among the best-executed final episodes in the franchise.

Yuno attends the captains' emergency meeting. He is no longer the composed, quietly confident young mage from earlier episodes. He has seen half his squad killed. He has watched Zenon defeat him effortlessly. He knows, now, that he is the prince of the Spade Kingdom — a fact that reframes his entire understanding of who he is. He makes a declaration: he will become the Wizard King. Not because of his bloodline. Because that is who he has always been and always will be, regardless of what anyone else decides about his origin.

The episode's structure builds toward one revelation that the show has been protecting since the very first episode. During the Devil-Binding ritual — during the fight between Asta and Liebe — Liebe's memories surface. We see his past in full.

Liebe was a devil born without magic. In the underworld, where magic determines worth the same way it does in the Clover Kingdom, having no magic made Liebe worthless. He was abused by other devils. He was tormented for years. One day, he fell — or was thrown — through a connection between worlds and ended up in the human realm. He was found by a woman who lived alone, outside of society, because her magic — the ability to unconsciously absorb and drain any magic around her — made it impossible for her to live among people without harming them. She was isolated by her own power. She was lonely. And she took in a small devil without magic because he was the only being she had ever met that she could be near without hurting.

Her name was Licita. And she was Asta's mother.

Licita raised Liebe. She gave him food, shelter, the first genuine kindness he had ever received. They were a family — a woman with killing magic and a devil without magic, isolated from the world together. Liebe loved her. And then Lucifero, the King of Devils, reached through to the human world and tried to use Liebe's body as a vessel. Licita could not let a high-ranking devil take over her family member. She sealed Liebe into the four-leaf grimoire — the only grimoire without an owner, the one that could hold a devil — sacrificing her own magic and life force in the process to complete the sealing. The grimoire became five-leaf. Liebe was inside it. Licita was dying. Asta — a baby — was left at the church in Hage.

Liebe, when Asta holds out his hand, recognizes him. He is Richita's son. They are brothers.

The episode ends with the formation complete. Asta and Liebe as equals. Yuno making his declaration. The Magic Knights preparing to raid the Spade Kingdom. And the final shot: the faraway future that Asta has been running toward his entire life, finally coming into view — not as a destination but as a direction. The series cuts to black. A title card: the story continues. The anime's initial television run was over.

New Character Spotlight — Nacht Faust

Nacht is one of the most efficiently and effectively introduced characters in the Black Clover anime. He appears for only a few episodes but his impact on the story and the thematic weight he carries is disproportionate to his screen time.

He is the argument that competence and moral clarity do not require optimism. Nacht is not a good person by his own assessment — he is someone who did something unforgivable and has spent years using the consequences of that action as a weapon against worse things. He does not want to be redeemed. He wants to be useful. These are different goals, and the distinction matters to his character in ways that Season 4 only begins to develop.

His shadow magic — the ability to use shadows as portals, constructs, and weapons — is visually distinctive and tactically flexible. His four-devil contract system, where different devils enhance different aspects of his power when merged with, gives his combat sequences a layer of strategic variation that most characters do not have. His role as Asta's trainer in the Devil-Binding sequence makes him directly responsible for the most significant power development in the franchise's anime run.

And his relationship with Yami — old friends, estranged by tragedy, reunited by necessity — is one of the most unexpectedly warm threads in a season full of loss. Yami telling Nacht that friends do not need reasons to save each other, and Nacht's grudging, emotional acknowledgment of that, is a moment of genuine humanity in a character who has been performing coldness for years.

Major Revelations This Season

Yuno is Prince of the Spade Kingdom

The revelation that Yuno is the missing heir of House Grinberryall — the royal family deposed by the Zogratis siblings — reframes his entire backstory and adds geopolitical stakes to his rivalry with Asta. He was not just found at a church. He was smuggled out of a dying kingdom by a man who gave his life to keep him safe. The necklace he has worn since childhood is a royal keepsake from parents he never knew. His drive to become the Wizard King gains a new dimension: he is also the legitimate ruler of the Spade Kingdom, and what he does about that will define the next phase of the story.

Asta's Mother is Licita, and Liebe is His Brother

The series finale reveals the complete truth about both Asta's origin and Liebe's. Licita was a woman with magic that unconsciously absorbed and drained the life force of everything around her — the inverse of Asta's situation. She could not live near anyone. She found Liebe. She raised him. She died sealing him into the grimoire to protect him from Lucifero. The five-leaf clover grimoire is not just Asta's weapon. It is his mother's sacrifice, his brother's prison, and the thing that made both of them who they are. Asta and Liebe are not user and devil. They are brothers who lost the same mother to the same enemy.

The Contract of Equals

Conventional devil-binding creates a master-servant relationship. Asta's contract with Liebe is unprecedented — it is a partnership between equals, without guaranteed compliance mechanisms, based purely on mutual understanding and genuine care. Nacht calls it foolish. It is also correct — it is the only framework that could work between these two specific people. The contract of equals sets up the Devil Union system that the new anime will develop fully: the ability for Asta and Liebe to merge fully, combining their capacities in ways the master-servant model cannot achieve.

Themes and Highlights

The Training Pays Off

Season 4 is, among other things, a payoff machine. Everything the anime-canon training episodes built — Luck's natural lightning, Leopold's endurance, Charmy's true power, Noelle's Mermaid Form, Yami's Mana Zone mastery — arrives in the Heart Kingdom battles and delivers exactly what the setup promised. The show spent considerable time developing these characters' growth. Season 4 spends considerable time showing why that growth mattered.

The Weight of Captivity

Yami's capture is the season's emotional anchor. He is the person who built the Black Bulls from nothing. The squad's identity — its chaos, its warmth, its specific flavor of dysfunctional family — is inseparable from him. His absence is immediately felt not just narratively but emotionally. The Black Bulls without Yami are people without a home, which is exactly what the show uses Nacht's cold competence to contrast against. Nacht is everything Yami is not, which makes the season's progression toward saving Yami feel urgent in a way that abstract stakes cannot manufacture.

Asta and Liebe as Brothers

The contract of equals works thematically because of everything the finale reveals. Asta did not choose to be kind to Liebe because he calculated that it would produce better combat results. He was kind to Liebe because Asta is who he is — someone who refuses to treat any person, human or devil, as less than a person without evidence. That instinct, applied to Liebe, happened to be exactly right. Not because the show rewards kindness with power. Because Licita's son meeting Licita's other son was always going to produce this outcome. They are, at the most fundamental level, family.

Season 4 Highlights

Asta halving the Candelo citadel in a single blow — the training's definitive payoff moment. Luck transforming himself into a living lightning bolt to bypass Svenkin's defense. Charmy's adult form debut and the consumption of Halbet's entire magic. Grey transforming Gauche's wound into healed flesh — the beginning of her real power's reveal. Dante versus Yami — the season's most spectacular battle. Yami throwing his katana to Asta as he is captured. Nacht walking into the captains' meeting and dismantling every assumption with five sentences. The Devil-Binding sequence — Asta thanking Liebe, the contract of equals, Nacht's genuine smile. And the finale — Liebe's backstory, Licita's sacrifice, the revelation that they are brothers — which is the most perfectly constructed emotional payoff in 170 episodes of a show full of emotional payoffs.

Why the Series Ended Here

The abrupt end of the Black Clover anime after 170 episodes was not a creative decision but a production one. Studio Pierrot was running the show as a weekly series that had been airing continuously since October 2017 — three and a half years without a major production break. The animation quality during that run was uneven partly because of the relentless schedule. The manga, meanwhile, had continued advancing to story content that would have required significantly more resources to adapt faithfully than the weekly model could accommodate.

The decision to end at episode 170 was announced in February 2021, before the season finished airing. It was positioned not as a cancellation but as a conclusion of the television run, with a film to follow. The film — Black Clover: Sword of the Wizard King — was released on Netflix on June 16, 2023, covering an original story set during the timeskip. And at Anime Expo in July 2025, the new Black Clover anime season was announced for 2026, produced by Pierrot and set to adapt the Spade Kingdom Raid arc — exactly the content that Season 4 was building toward. The story is not finished. It is just taking the runway it needed.

Conclusion — Is Season 4 Worth Watching?

Without question. And if you have watched Seasons 1 through 3, watching Season 4 is not optional — it is the bridge between everything that came before and everything that is coming in 2026.

Sixteen episodes is a short season for a show this scale. But those sixteen episodes contain the introduction of Nacht Faust, the fall of the Heart Kingdom, Yami's capture, the revelation of Yuno's royal bloodline, the contract between Asta and Liebe, and the reveal of Asta's mother — the most emotionally significant single piece of information in the entire series to that point. The density of what Season 4 accomplishes is extraordinary for its length.

The finale — episode 170, "The Faraway Future" — is one of the best final episodes of any major shonen series in recent memory. It closes the immediate narrative while opening something much larger. Asta and Liebe shaking hands as brothers is the series saying: we know what this story is about. It has always been about this. And it is not finished.

Watch it. All sixteen episodes. Then watch the film. Then wait for 2026. The Spade Kingdom raid is coming. Everything Season 4 built is about to pay off at scale.

FAQ

Q: How many episodes does Black Clover Season 4 have?

A: Season 4 has exactly 16 episodes — episodes 155 through 170 of the overall series. It aired from December 8, 2020 to March 30, 2021. It is the shortest season of the run, but also one of the most narratively dense.

Q: Which episodes are filler or anime-original in Season 4?

A: Episodes 155, 156, and 157 are anime-canon original content supervised by Yūki Tabata, covering the final stretch of the Heart Kingdom training period. They are not pure filler — they are considered part of the official anime continuity and directly connect to the manga-faithful episodes that follow. Episodes 158 through 170 adapt the manga directly.

Q: Who is Nacht Faust?

A: Nacht Faust is the vice-captain of the Black Bulls — a fact that almost nobody in the show knew, because he spent years undercover as a spy in the Spade Kingdom. He is a shadow magic user and a devil host, having bound four devils to himself through forbidden Devil-Binding rituals. He serves as Asta's trainer for the Devil-Binding sequence and as the strategic architect of the Spade Kingdom raid plan. He was friends with Yami in their youth, estranged by tragedy, and reunited by necessity. He is one of the best new characters the franchise introduces in any season.

Q: What is the Tree of Qliphoth?

A: The Tree of Qliphoth is a ritual that the Dark Triad is attempting to complete using Yami's Dark Magic and William Vangeance's World Tree Magic. When completed, it opens a connection between the human world and the underworld, allowing every devil in the underworld to manifest in the human world. The Dark Triad's entire campaign — capturing Yami and Vangeance, attacking the Clover and Heart Kingdoms — is in service of making this ritual happen. Stopping it before it completes is the primary objective of the Spade Kingdom raid.

Q: Why is the reveal about Asta's mother so significant?

A: Because it connects Asta, Liebe, and Lucifero — the most powerful devil — into a single personal narrative. Licita, Asta's mother, died sealing Liebe into the five-leaf grimoire to prevent Lucifero from possessing Liebe. The grimoire Asta carries is literally his mother's sacrifice. Liebe, who Asta just contracted as an equal, is his brother — raised by the same woman. And Lucifero, who is the primary devil threat in the Spade Kingdom arc, is the entity responsible for Licita's death. Asta's fight against Lucifero is not just a battle to stop the underworld from opening. It is personal. It has been personal since the moment Asta was left at the church in Hage.

Q: What is the new anime announced for 2026?

A: At Anime Expo in July 2025, a new Black Clover anime was announced, produced by Studio Pierrot and set to premiere in 2026. It is positioned in Japan as a "second season" of the franchise (since the first 170 episodes ran continuously without formal seasonal breaks in Japan). It will adapt the Spade Kingdom Raid arc — the content that Season 4 was directly setting up — and continue the story from where episode 170 left off. The film Black Clover: Sword of the Wizard King (Netflix, June 2023) covers a standalone story set during the timeskip and is recommended viewing before the new season premieres.

Q: Where can I watch Black Clover Season 4?

A: All seasons of Black Clover are available on Crunchyroll in both subtitled and dubbed formats. The film is available on Netflix.
