Chapter Summaries

Ailin killed Genryu Ryudoji and his retainers, then used his Zanpakuto’s Bankai to cut through the world’s barrier and send a replicated version of himself into the spatial currents. As the Seireitei recovered from Aizen Sosuke’s defeat, Yamamoto convened a meeting to address the Reikaku creator and Yhwach’s expected return.

• Genryu Ryudoji ordered his retainers to kill Ailin, but Ailin impaled all seven with Zanpakuto from Gate of Babylon.

• After returning from the Dangai, the captains learned they had lost fourteen days, and Yamamoto called a Captain’s Meeting to discuss the Reikaku creator and Yhwach’s return in two years.

Ailin realized his past self had been summoned as Berserker in the Fourth Holy Grail War and considered whether the corrupted Grail could help Hollow Ailin. Kariya Matou summoned Ailin’s past self, then set out to take Sakura away from Zouken Matou.

• Ailin recalled that his past self had entered the Type-Moon world and wondered whether the Holy Grail’s corruption could help Hollow Ailin advance.

• Kariya Matou declared that he would take Sakura away, and Zouken Matou dispersed into Crest Worms rather than stop him.

Zouken Matou let Kariya Matou leave with Sakura, confident he could reclaim her after the Holy Grail War. Ailin, summoned as Berserker, explained his altered abilities to Kariya and assessed his chances against the Servants whose battle he had witnessed.

• Zouken Matou reflected that Sakura was essential to his plan to take over a body and extend his life, and believed Tokiomi Tohsaka would return her to the Matou Family if Kariya took her away.

• Ailin explained that Madness Enhancement had changed his powers, sealed his Kido and Bankai, and prevented him from speaking, though he could communicate by writing.
• Ailin saw Gilgamesh's golden spatial gates kill a masked figure with two Noble Phantasms in central Fuyuki City.
• Kariya Matou asked Ailin about the battle and his chances against the two Servants; Ailin said he could beat the weaker one and was stronger than the other in a fight without Noble Phantasms.

Kariya Matou sent Berserker to the Tohsaka Estate to kill Tokiomi Tohsaka, but Berserker encountered Gilgamesh and began a clash of weapons with him. The chapter ended as Gilgamesh prepared to use a Noble Phantasm and Berserker readied a Zanpakuto, unable to invoke its true name.

• Gilgamesh and Berserker exchanged volleys of weapons as observers across Fuyuki watched their battle.
• Gilgamesh summoned a crimson spear, and Berserker prepared a Zanpakuto despite being unable to invoke its true name.

Ailin and Gilgamesh fought at the Tohsaka Estate until a sniper targeted Kariya Matou, prompting Ailin to use his Bankai to save him and end the battle. Ailin returned with Kariya to Sakura, who was waiting for her usual basement training, and Kariya promised she would no longer have to suffer.

• Kariya found Sakura waiting outside for her basement training, promised she would never have to suffer again, and held her as she cried.

Kariya Matou learned that Ailin could heal him and Sakura, but chose to keep his Crest Worms and mana for now so Ailin could remain in the Holy Grail War. Ailin healed Sakura, and Kariya decided they would visit the Matou Residence the following night; he also learned that Ailin had regained his speech and gained new abilities.

• Ailin reassured Kariya Matou that they were compatible and revealed he could use a Noble Phantasm to restore Kariya and Sakura from the Crest Worms' damage.
• Kariya Matou asked Ailin to heal Sakura first, keeping the Crest Worms in his own body so he could supply mana and pursue the Holy Grail War.

After Maiya Hisau died from her injuries, Kiritsugu Emiya learned that Kariya Matou was the Master of the black-flamed Berserker and struggled between seeking revenge and needing Berserker to counter Gilgamesh. The day after the battle, the other Masters and Servants made their moves while Kiritsugu decided he could not afford to kill Kariya yet.

• Maiya Hisau woke in Kiritsugu Emiya's clinic, warned him about the black-flamed Servant and its injured, white-haired Master, then died after refusing Irisviel's healing.
• Kiritsugu Emiya burned Maiya's body and, after investigating, identified the white-haired Master as Kariya Matou, who had changed drastically in a year.
• Saber and Irisviel arrived in Fuyuki City, while Kirei Kotomine sought a new estate and Sola became captivated by Diarmuid Ua Duibhne.
• Kirei Kotomine entered the church under the protection rules for Masters who had lost their Servants, while Ryunosuke Uryu searched for victims and Tokiomi Tohsaka stayed at home.
• Waver and Iskandar went shopping, and Kiritsugu Emiya reviewed intelligence and learned that Gilgamesh was Archer.
• Kiritsugu Emiya wanted to kill Kariya Matou and Berserker for Maiya's death, but concluded that Berserker was needed to oppose Gilgamesh.

Ailin and Kariya Matou went to the Matou residence to kill Zouken Matou, and Ailin froze the Crest Worms and Zouken’s fleeing host worm. They then reached the port, where Ailin joined Saber Artoria and Lancer Diarmuid Ua Duibhne for a proposed three-way battle, while Saber remained concerned about Irisviel’s safety.

• Ailin sensed Lancer Diarmuid Ua Duibhne challenging the Servants, but chose to take Kariya Matou to the Matou residence first to deal with Zouken Matou.
• Zouken Matou tried to flee while his Crest Worms swarmed Ailin and Kariya, but Ailin detected the escape attempt and Kariya ordered him to kill Zouken.
• Ailin released Sode no Shirayuki and froze the Matou residence, killing the Crest Worms and the worm carrying Zouken’s soul before bringing Kariya outside.
• Kariya decided he would not return Sakura to the Tohsaka Estate if he survived the war, then went with Ailin to answer Diarmuid’s challenge.
• At the port, Ailin arrived during Saber Artoria and Diarmuid’s duel, and Diarmuid proposed that all three fight together.
• Artoria hesitated because she was guarding Irisviel, but Irisviel urged her to fight; Artoria still worried Lancer’s Master might attack Irisviel during the battle.

Ailin fought Artoria and Diarmuid at once, relying on swordsmanship to challenge both Heroic Spirits while studying Excalibur. When Ailin unleashed a massive slash, Artoria answered with Wind King's Hammer, and the battle continued at full strength.

• Ailin created a barrier around Irisviel that could withstand a B-rank Noble Phantasm, allowing Artoria and Diarmuid to fight without worrying about her safety.
• Ailin and Artoria exchanged sword strikes, and Diarmuid joined them, forcing Ailin and Artoria to work together to drive him through a shipping container.
• Ailin focused on analyzing Excalibur with Synchronization while his swordsmanship pressed Artoria, and Diarmuid returned to attack Ailin alongside her.
• Ailin unleashed a massive slash through swordsmanship alone, astonishing Artoria and Diarmuid with its power.
• Artoria declared she would not disappoint Ailin and countered his slash with Wind King's Hammer.

Artoria revealed Excalibur and joined Diarmuid in a renewed fight against Ailin at the harbor. Ailin held his own against both heroes, while Irisviel watched from the protection of Four-Sided Dankū as their battle devastated the area.

• Artoria revealed Excalibur, allowing Diarmuid to recognize her as the King of Knights, while Ailin identified Diarmuid as the Child of Light of Ireland.
• Diarmuid charged Ailin with his Noble Phantasms, but Ailin's powerful sword slash forced him backward.
• Artoria used Mana Burst to attack Ailin, and her strength initially knocked him back before his sword skill let him match her in repeated clashes.
• Ailin used a second Zanpakuto to block Diarmuid while continuing to fight Artoria, prompting her to gather Wind King's Hammer around Excalibur.
• The three Servants exchanged attacks that destroyed much of the harbor as Irisviel watched from inside Four-Sided Dankū.

Iskandar, Kiritsugu, and Kariya watched or assessed the battle between Ailin, Artoria, and Diarmuid as Ailin analyzed their Noble Phantasms and gained the advantage. Kiritsugu found Kariya and approached him with the intent to form an alliance against Archer, while expecting to win the war afterward.

• Waver overcame some of his fear while Iskandar watched the harbor battle and considered recruiting the powerful heroes to help fulfill his wish.
• Kiritsugu judged that Saber could not defeat the strongest Servants, searched for their Masters, and located Kariya but failed to find Lancer's Master.
• Ailin analyzed Excalibur and Diarmuid's two spears, then used his dual-sword skills to suppress Artoria and Diarmuid.
• Kiritsugu drove to Kariya's hiding place and approached him, intending to persuade him to join forces against Archer.

Kiritsugu Emiya proposed an alliance between Saber and Kariya Matou, who reconsidered after Kiritsugu mentioned Tokiomi Tohsaka. Meanwhile, Ailin overwhelmed Saber and Diarmuid at the harbor, while Iskandar and Waver watched from afar.

• Kiritsugu Emiya introduced himself to Kariya Matou and proposed an alliance, but Kariya initially refused because he trusted Berserker to win.
• Kiritsugu argued that Saber’s A++-rank Noble Phantasm could help defeat Archer, and Kariya remained unmoved until Kiritsugu brought up Tokiomi Tohsaka.
• Kariya agreed to consider the alliance and planned to consult Berserker, while Kiritsugu resolved to investigate Kariya’s connection to Tokiomi.
• Ailin used his Zanpakuto to overpower Artoria and Diarmuid with immense slashes, leaving both convinced they might soon be defeated.
• Iskandar rose from the bridge framework to watch the distant battle, while Waver feared that Rider might not withstand the attacks.

Iskandar rushed into Ailin’s battle with Artoria and Diarmuid, but Ailin shattered his combined Noble Phantasm with a single attack. After exchanging names, Iskandar invited Ailin, Artoria, and Diarmuid to join him and yield the Holy Grail.

• Iskandar summoned the Thunder-Hooved Steed and Chariot of Divine Might, then charged toward Ailin, Artoria, and Diarmuid to break up their fight.
• Ailin met Iskandar’s Ionioi Hetairoi head-on with Crescent Moon Cross Slash and destroyed the chariot, though Iskandar protected Waver.
• Ailin identified himself as a Berserker and a captain of the Gotei 13, while Iskandar introduced himself as the King of Conquerors.
• Iskandar admired Ailin’s spatial Zanpakuto and asked him, Artoria, and Diarmuid to serve under him and surrender the Holy Grail.

Ailin rejected Iskandar’s offer to join him and mocked the kings before clashing with Gilgamesh. After Ailin unleashed Nozarashi and shattered Gilgamesh’s barrage with a single slash, Gilgamesh drew Ea, setting the stage for their next exchange.

• Artoria refused Iskandar’s invitation, and Diarmuid declined because he had pledged loyalty to his Master.
• Ailin rejected Iskandar and insulted him, Artoria, and Gilgamesh, prompting Gilgamesh to attack from above the harbor.
• Ailin transformed his Zanpakuto into Elucidator and Dark Repulser and used Star Burst Air Slash to deflect Gilgamesh’s weapons while charging him.
• Gilgamesh increased his barrage, but Ailin released Nozarashi and destroyed the incoming Noble Phantasms with a single slash that split the sky.
• Gilgamesh drew Ea after Ailin’s attack, while the watching Servants and Irisviel reacted with shock to Ailin’s power.

Ailin abandoned his attempt to analyze Ea and rushed to save Kariya Matou after Kiritsugu Emiya killed him. After Ailin revived Kariya, Sakura Matou received Command Spells and became Ailin’s new Master, leaving Kariya shocked by the change.

• As Gilgamesh prepared to unleash Ea, Ailin lost Kariya Matou’s magical energy support and realized Kariya had likely been killed, so he fled toward the hotel.
• Iskandar stopped Gilgamesh from pursuing Ailin, and the kings argued over who deserved the title of king.
• Ailin reached the hotel, found Kariya dead with his soul intact, and used Minazuki to revive him with a restored body.
• Kariya learned that his recovered body no longer supplied magical energy, meaning he was no longer Ailin’s Master, and urged Ailin to return to his new Master.
• Sakura revealed three Command Spells and told Kariya that she was Ailin’s new Master, which Ailin confirmed.

After Kariya explained the danger of the Holy Grail War, Ailin took Sakura into the night sky to help her adjust to fighting as his Master. They spotted Sakura’s sister Rin following the trail of Caster and Ryunosuke Uryu, and Ailin moved to intervene before she became their victim.

• Kariya told Ailin that Sakura would be safer fighting alongside him than staying at home, where Kiritsugu Emiya could attack her.
• Sakura chose to accompany Ailin, who carried her above Fuyuki City and showed her its nighttime scenery.
• Ailin recognized Rin Tohsaka following a magical-energy trail with a gemstone and remembered that Ryunosuke Uryu had abducted her friend Kotone.
• Sakura asked Ailin to save Rin after learning a Servant’s magical energy was nearby, and Ailin agreed to stop Caster and Ryunosuke Uryu.
• Ailin appeared in front of Rin, whose gemstone grew hot as she sensed his magical energy.

Ailin rescued Sakura and Rin, then captured Ryunosuke Uryu and Gilles de Rais and brought them to Mion River Port. He had Flesh Rip punish Ryunosuke while attacking Gilles, who summoned sea monsters from the river.

• Rin attacked Ailin, but he stopped her and explained that Sakura was safe and that he intended to confront the Servant ahead.
• Ailin used Heaven's Chain to seize Gilles de Rais and Ryunosuke Uryu from Ryunosuke's house, where neighbors discovered four captive children and evidence of the killer's crimes.
• Ailin carried Sakura and Rin to Mion River Port, where he questioned Gilles about Joan of Arc and released him when he became distracted.
• Ailin manifested Flesh Rip with Muramasa's Bankai and sent her to punish Ryunosuke, whose senses Ailin had heightened with Kyoka Suigetsu.
• Ailin attacked Gilles with dozens of Zanpakuto, but Gilles summoned sea monsters from the Mion River using his Noble Phantasm, Teachings of the Abyss.

Ailin used Hyōrinmaru to freeze and kill Gilles de Rais’s Abyssal Sea Demon, then erased the corrosive ice with Cero and left with Sakura. The other Servants sensed Ailin’s stronger aura, while Kiritsugu wondered who had become Berserker’s new Master.

• Ailin froze the Mion River and used Ice Heaven Hundred Flower Funeral to kill the Abyssal Sea Demon summoned by Gilles de Rais.
• Ailin erased the ice and corrosive blood with Cero, then carried Sakura and Rin Tohsaka away from the harbor.
• Ailin left Rin in the city and warned her not to go out at night before returning with Sakura.
• Iskandar sensed Ailin’s stronger aura and decided to challenge Berserker at their next meeting.
• Gilgamesh, Artoria, Diarmuid, and Assassin also sensed Berserker’s increased presence, while the Masters suspected Kirei Kotomine had become his new Master.
• Kiritsugu, injured after escaping Ailin’s strike, questioned whether the Einzbern Family’s intelligence had missed a magus who had secretly entered Fuyuki City.

Ailin upgraded several Zanpakuto in Unlimited Blade Works after gaining Sakura Matou as his Master, then accompanied Kariya Matou and Sakura around Fuyuki. When he sensed Iskandar nearby, the King of Conquerors approached to speak with him while asking Waver to check Ailin’s parameters.

• Ailin forged more than a hundred Zanpakuto from the sword-type Noble Phantasms he had seen Gilgamesh use, then improved Yellow Rose of the Demon-Breaking and Crimson Rose of Absolute Destruction by at least thirty percent.
• Ailin recovered his spiritual pressure through Sakura’s magical energy and followed Kariya Matou and Sakura through the city while they shopped.
• Ailin saw a television report about the murders committed by Ryunosuke Uryu and realized that Flesh Rip had not returned, suggesting Ryunosuke was still alive.
• Ailin sensed Iskandar nearby and appeared beside Kariya Matou and Sakura, alerting Kariya to a possible threat.
• Iskandar approached Ailin with Waver and a wooden barrel, loudly telling Waver to check Ailin’s parameters while he spoke with him.

Iskandar invited Ailin to the Banquet of Kings after meeting him in the city, and Ailin accepted despite Kariya Matou’s fears that the kings might join forces against him. Ailin left Sakura behind with a Zanpakuto to protect Kariya and prepared to attend the banquet, where he intended to speak with Artoria.

• Waver examined Ailin’s parameters and urged Iskandar to flee, but Iskandar instead tried to recruit Ailin.
• Ailin rejected Iskandar’s offer to join his ranks and initially declined the invitation to a banquet with Gilgamesh and Saber.
• Iskandar named the gathering the Banquet of Kings and invited Ailin to explain the great kings of his world.
• Kariya Matou worried that the three kings might attack Ailin together, but Ailin decided he had to attend and arranged for Sakura to stay home with a Zanpakuto protecting Kariya.
• That night, Ailin stood in the sky above Fuyuki City as Iskandar and Waver rode toward the suburbs in the Chariot of Divine Might.
