Chapter Summaries

Artoria underwent the Holy Sword Purification Ritual and glimpsed another fragment of the wielder’s battle with Zeus, but she woke before seeing who won. Exhausted, she prepared herself to undergo the same ritual as Alice.

• Shi finished applying the substance to the Holy Sword and confronted the wielder about his refusal to let her go.
• The wielder asked Shi to perform the Tai Chi Combination Ritual, and Shi demanded that he not perform it with Shiki.
• Artoria lost consciousness during the ritual and saw Zeus’s spear pierce the wielder and the space around him.
• Artoria regained consciousness and saw Alice completing the Holy Sword Purification Ritual through the scabbard’s neighboring passage.
• Artoria accepted that she would undergo the ritual herself, while Jeanne remained exhausted from the SAP Ritual.

Jeanne struggled with her shame and growing attraction to the bizarre Holy Sword purification ritual while sharing breakfast with Karen. At Mount Enzou, Matou Zouken discovered the Greater Holy Grail’s corrupted darkness and devised a way to pursue the Root without waiting for enough Servants to be eliminated.

• Jeanne endured the Holy Sword ritual until morning and feared she was becoming accustomed to it and enjoying it.
• At breakfast, Jeanne tried to distract Karen from her father’s withdrawal from the Holy Grail War, and he teased Jeanne about her pregnancy before she stomped on his foot.
• Matou Zouken examined the Greater Holy Grail and found a conscious, black-mud-like darkness that could descend into reality through the wish-granting mechanism.
• Matou Zouken concluded the Grail’s corruption made its wishes dangerous and considered a method inspired by Bluebeard’s actions to open a path to the Root without waiting for enough Servant souls.
• Matou Zouken noted that Archer and Berserker could provide enough souls to activate the Grail, but activation alone might not ensure a stable passage to the Root.

Matou Zouken prepared to summon an Evil God at Mount Enzou, using Archer as bait and Berserker to bind him to the creature. Bai Yue discovered that Zouken was draining Fuyuki City's leylines and destroying the Holy Grail System, while Luviya Serlinta felt the resulting tremors.

• Matou Zouken used Berserker to practice turning Archer into a weapon and prepared an insect-built altar at Mount Enzou.
• Bai Yue returned after striking one of Matou Zouken's soul fragments and discussed asking Ryougi to kill the old magus, but found the original personality absorbed in a movie.
• Bai Yue traced the abnormal mana beneath Fuyuki City to Mount Enzou and realized Matou Zouken had lured him away while preparing a major operation.
• Bai Yue sensed Mount Enzou's barrier warping, its energy nearing a burst, and his connection to his summoning master flickering as the Holy Grail System collapsed.
• Luviya Serlinta felt the tremors spill tea onto her outfit and chose not to mock her companion, whose father had suffered an accident.

Tohsaka Rin and Luviya witnessed a monstrous being emerge where Mount Enzou had stood, and Rin barely escaped a dreamlike trap that knocked out most of Fuyuki City. Archer prepared to unleash Enuma Elish against Archer of the Red faction, while Rin and Waver feared their opposing attacks would destroy the city.

• Rin and Luviya sensed the same horrifying presence they had encountered the night before, and their Servants carried them to safety as Mount Enzou’s barrier appeared and vanished.
• A huge, flickering monster emerged in Mount Enzou’s place and emitted a cry that knocked out nearly everyone in Fuyuki City.
• Rin nearly fell into a dream of her father before an unknown voice warned her, and she woke aboard the Golden Flying Ship and urged Archer to destroy the monster.
• Archer raised Enuma Elish as Archer of the Red faction prepared the same weapon from a ship fused with the monster, while Berserker stood behind him.
• Rin feared the two attacks would devastate Fuyuki City, and Waver asked Rider whether he should hide inside the Army of the King.

Iskandar’s Reality Marble and Black Caster’s city both failed to contain the clash of the two Ea swords, while Artoria and others redirected the remaining shockwaves away from the city. The Holy Grail then poured black mud into the surviving monster, and as it began spreading corruption, the Black Servants gathered into light around their motionless master, who returned and took over.

• Waver used his Command Seals to strengthen Iskandar as Artoria and Alice arrived near Mount Enzou to redirect the swords’ shockwaves.
• The two Ea swords shattered Iskandar’s Reality Marble and Black Caster’s ancient city, but Artoria and another beam of light sent the remaining force skyward.
• The clash destroyed most of Mount Enzou, while the monster’s fragments regenerated in black mud that poured from the Holy Grail and helped it gain a body.
• Jeanne attacked the regenerating monster with her blazing light blade, but the Holy Grail merged into it and released still more black mud.
• Jeanne’s master returned from his motionless state, transferred away his price, and began disappearing with the Black Servants as they turned into particles of light.
• The monster’s gaze nearly immobilized Artoria as black mud spread toward her, and she raised Excalibur to attack again.

Artoria discovered that the apparent victory over the Evil God was an illusion, as the black mud corrupted the mechanical army and overran Fuyuki City. She fought to reach Alice but was intercepted by Berserker, whom she recognized as Lancelot, while he slaughtered civilians.

• The Evil God opened a path to the Root, and the original personality explained that he could handle it as particles of light gathered to reveal his true form.
• He appeared in ancient attire, suppressed the Evil God's influence with a mental barrier, and summoned a colossal metal fortress to fight R'lyeh City.
• The metal fortress initially overwhelmed the Evil God's monsters, but Artoria sensed that the apparent victory concealed a danger.
• Artoria realized the black mud had corrupted the mechanical puppets and spread across Fuyuki City, while Alice failed to respond to her.
• Artoria tried to reach Alice through the chaos, but Berserker attacked and killed people; she recognized him as Lancelot when their swords clashed.

Artoria realized her apparent defeat against Lancelot had been an illusion, while Ryougi lost her connection to the Root and became fully human. With Ori and Shiki now independent, they turned against Ryougi and prepared to make her undergo the ritual.

• Artoria defeated Lancelot and pierced his heart, then learned he had wanted her to judge him and that the Hellish battlefield was an illusion.
• The illusion vanished, revealing the metallic construct overlapping the path to the Root as the evil god and Fuyuki City faded away.
• Ryougi entered the mansion at the Root and lost her connection to it, experiencing physical sensations and emotions as an ordinary human.
• The three personalities appeared as separate people, and Ori proposed making Ryougi endure the humiliating ritual.
• Ryougi tried to flee and reconnect with the Root, but Shiki tackled her and sided with Ori.

After Ryougi Shiki restored Mount Enzou and received control of the Mechanical Holy Body, plans were made to connect the Type-Moon world with Hakone World and bring two beings into the Counter Forces. In the aftermath of the Fourth Holy Grail War, Artoria chose to accept her original fate, while the survivors prepared for the next decade and beyond.

• Ryougi Shiki restored Mount Enzou with the Root’s power, and Ori and Shiki shared control of the Mechanical Holy Body.
• He planned to integrate two reincarnated beings into Gaia and Alaya Consciousness and explained that communication between the Type-Moon world and Hakone World would take about ten years to synchronize.
• Artoria decided not to alter her fate and considered meeting and atoning to her former companions through future Holy Grail Wars or missions to Parallel Worlds.
• Jeanne remained behind as Karen’s guardian, while Irisviel took responsibility for raising Illya after the head of the Eizenbern family died.
• Tohsaka Rin declined to ask for her father’s resurrection and challenged Luviya Serlinta to a rematch ten years later.

Lainas took control of the El-Melloi faction while preparing to compete in the Holy Grail War ten years later, and Bai Yue woke to find Black Rabbit caring for him. Meanwhile, Al-chan and Kaling wagered the product of the Holy Sword Purification Ritual while fiercely competing in video games.

• Lainas became the El-Melloi faction's designated heir and resolved to prepare for the next Holy Grail War.
• Black Rabbit explained that she had stayed behind to care for Bai Yue while the others went to the Harvest Festival.
• Bai Yue teased Black Rabbit about apologizing and asked her to make him a bath pouf from her rabbit fur.
• Al-chan and Kaling continued their game-console contest, with the loser having to drink a cup of the Holy Sword Purification Ritual's product.
• Kaling had accumulated thirty cups, while Al-chan had accumulated twenty.

Bai Yue discovered that Algol and Lady Kaling had wagered extracted material from their scabbards in a Gift Game and demanded an equal exchange from the Holy Sword’s material. As the group traveled to Underwood, he revealed that Azdahaka was sealed in the North Area, alarming Black Rabbit.

• Bai Yue woke and caught Algol and Lady Kaling trying to take the parchment recording their wager, then demanded an equal amount of material from their scabbards in exchange for the Holy Sword’s extract.
• Bai Yue and Black Rabbit arrived with their companions at Underwood, where the Dragon Horned Griffin Lion was hosting the South Area Harvest Festival.
• Black Rabbit learned from Bai Yue that Azdahaka was sealed in the North Area and that the Ouroboros Alliance intended to break the seal.
• Bai Yue hugged the frightened Black Rabbit in the carriage and teased her about objecting to the scabbard-material transaction near No Name’s children.

Leticia and Sarah discovered that the Giant race’s attack was meant to distract them while the Ouroboros Alliance tried to find Leticia’s sealed sister, Lamia Declayre, who bore a curse rivaling hundreds of millions of Demon Gods. As the attack spread, Asuka sent Deen to fight the giants outside Underwood while a masked female knight battled those inside the city.

• Sharat Dorek warned the Community leaders to stay alert during the Harvest Festival, and Leticia later asked Sarah and Lamia to accompany her outside Underwood.
• Leticia and Sarah prepared to leave, but the Giant race attacked the city, and Lamia feared they were trying to break her mother’s seal.
• Leticia explained that her sister Lamia Declayre bore a terrible curse and that the enemy might locate the seal using blood taken from Lamia.
• Leticia realized the Giant race were meant to hold them back and saw that other attackers had joined the assault.
• Asuka rode Deen outside the city to fight the giants there while a masked female knight dealt with the giants inside Underwood.
• Deen punched a giant, sending it crashing into several others.

Black Rabbit and Bai Yue redirected a magically created flood toward the invading giants, with Black Rabbit adding lightning to devastate their forces. The attack left the giants and monsters crushed in a crater of boiling water as Aisha watched in horror.

• Asuka ordered Deen to stop holding back, and he charged into the giants, crushing their heads with powerful blows.
• Kasukabe Yao held back against an attacking Griffin, and she and Aisha then faced bombardment from a six-headed giant.
• Yao and Aisha saw a colossal flood rushing toward the underground city, while Asuka and Izayoi intercepted some of the incoming rocks.
• Bai Yue arrived with Black Rabbit, stopped the flood from striking them, and had Black Rabbit electrify the monsters hidden inside it.
• Bai Yue shaped the flood into a water dragon and directed it over the city toward the giants, while Black Rabbit added a lightning dragon to the attack.
• The combined water and lightning crashed into the enemy camp, crushing and electrocuting the giants as Aisha vomited at the sight.

Bai Yue and the others learned that enemies planned to awaken Leticia’s sealed sister, whose uncontrolled Divinity could exceed the omnipotent realm. They set out for the sealing site with Vellazz Ignifatus, while strange fog and a possible Cthulhu connection remained ahead.

• Asuka berated Black Rabbit over the disgusting aftermath of the fight, and Bai Yue handed Black Rabbit a replacement for her wet clothing.
• Leticia told Bai Yue that the attackers intended to awaken her sister and unleash her immense, uncontrollable power.
• Vellazz Ignifatus appeared and repeatedly hit people with her hammer before Aisha restrained her and explained her weapon-throwing fetish.
• Bai Yue asked Vellazz Ignifatus whether the person who sent her had come along, and he suspected Yao’s father had sent her to help them reach the sealing site.
• Bai Yue’s group traveled by carriage toward the sealing site, and Kasukabe Yao accused him of comparing the women’s figures.

Bai Yue and his companions traveled through a strange, mind-affecting fog toward the source of its spiritual presence. After Kasukabe Yao realized what had been happening between Bai Yue and Leticia during the jolting ride, the carriage stopped before something moving in the fog.

• Bai Yue and the others set out by carriage, while Aisha, Leticia's niece, and Yao joined the journey hoping to help or see their fathers.
• Yao and Vera dislocated Bai Yue's arms after he teased Yao, and Vera questioned why he had not reacted to her hammer blow.
• The carriage entered gray spiritual fog that seeped through its barrier, but Bai Yue recognized its mind-affecting spiritual fluctuation as similar to the evil Cthulhu he had encountered before.
• As the carriage jolted through the fog, Yao noticed Leticia's discomfort and used her perception to realize that Bai Yue had been secretly purifying his Holy Sword and transferring what it produced.
• The carriage screeched to a halt, and the group saw something stirring in the fog ahead.

Yao and the others faced Ghatanothoa, whose petrifying gaze and rapid regeneration resisted their attacks. As their abilities seemed to grow weaker, Bai Yue told them the enemy was not weakening their powers, leaving the group to discover the cause themselves.

• Yao recognized the approaching monster as possibly Ghatanothoa, and its appearance shocked her and the others.
• Sarah, Lamia, and others began to petrify when they looked at Ghatanothoa, while Bai Yue warned them to avoid its eyes.
• Yao identified Ghatanothoa as a being from the Cthulhu Mythos, and the group found themselves atop a volcanic crater.
• Lamia, Vera, Yao, and Leticia attacked Ghatanothoa, but it rapidly regenerated from their damage and even recovered from Vera's karmic fire.
• Yao wondered whether their abilities were being weakened, but Bai Yue said that was not the cause and left them to work out the truth.

Leticia discovered that the evil god weakened their attacks through mental interference, and that powerful emotions could help them resist it. Her explanation left several allies embarrassed or frightened, while Vera’s terror and petrification worsened.

• Leticia noticed her attacks weakened less when she recalled the Holy Sword Purification Ritual, and she told Yao to picture it while attacking.
• Yao and Lamia found that recalling the ritual made their attacks stronger and slowed their petrification.
• Leticia explained that intense emotions could overcome the fear and subconscious doubt causing their powers to falter.
• Sarah recalled an emotionally charged memory and blasted away a third of the evil god, while Aisha’s attempts instead weakened her attacks and sped up her petrification.
• Vera mistook the evil god for a perverted stalker, and Aisha pressed Leticia and Yao to explain the ritual.
• Someone offered Aisha a profound emotional shock.

Bai Yue discovered that recalling a kiss with him let Aisha attack the evil god without her power weakening, and Leticia destroyed the monster. After the group returned to the hillside, Bai Yue supplied the girls with protective, self-cleaning outfits as they prepared to face more mental threats.

• Bai Yue kissed Aisha, restoring her attack's full power, and told her to recall the feeling when fighting the evil god.
• Leticia attacked the monster with shadow spears and a dragon-shaped shadow, destroying it and ending the false scenery.
• Aisha recovered on the hillside, and Sister Vera burned a grotesque remnant that flew toward her.
• Bai Yue gave Aisha replacement underwear and made Lamia a custom outfit after scanning her, then gave Kasukabe Yao a set as well.
• Bai Yue offered protective clothes to Sarah and Vera, and Aisha demanded a set because she had to materialize while fighting.

Bai Yue and the others reached the place where Leticia’s younger sister was being held, but Maxwell’s interference blocked their way. Bai Yue provoked Maxwell by kissing Vera, causing him to appear—only for an eerie wind to crush him instantly.

• Aisha traded teasing remarks with Bai Yue as he replaced her set of items, then he carried the Blonde Vampire Princess back into the carriage.
• Leticia used a Gift Card to reveal the hidden location, but Maxwell attacked them with flames that Bai Yue erased with an eerie wind.
• Vera and Leticia tried to open a door into the area, but Maxwell repeatedly connected their doors to his own and taunted Vera.
• Bai Yue kissed Vera to provoke Maxwell, and the space before them shattered as Maxwell appeared.
• Bai Yue’s eerie wind snapped shut around Maxwell and crushed him like a tomato.

Bai Yue forced Maxwell into a direct battle by provoking him while protecting Vera, and Maxwell unleashed a devastating attack with his Steel Angels. After the blast transformed the surrounding landscape, Maxwell and Bai Yue faced each other in angelic and demonic forms, with Vera unharmed and Maxwell preparing to self-destruct.

• Maxwell identified how Bai Yue used his own essence to lure and unleash Decadent Wind, and Bai Yue confirmed his deductions.
• Maxwell summoned Steel Angels, but Bai Yue's bizarre wind erased those that attacked him.
• Bai Yue carried Vera into a carriage, causing Maxwell and the Steel Angels to turn their attacks toward it.
• Leticia gathered Aisha, Lamia, Yao, and Sarah beneath her shadow wings as Maxwell's Steel Angels and mixed fire-and-ice energy exploded, devastating the landscape.
• Sarah saw Maxwell in a white, winged form opposite Bai Yue, who had black wings and still held an unharmed Vera.
• Bai Yue asked Vera to stand aside as Maxwell, consumed by hatred, gathered surrounding heat inside himself in preparation for self-destruction.

After Maxwell’s self-destruction, Bai Yue led Vera, Aisha, Lamia, and Leticia into a grotesque realm where the Vampire castle was being consumed by a living city. Leticia was trapped in a vision of her sister, but Bai Yue freed her and destroyed the monsters as the seal broke.

• Maxwell self-destructed, but Bai Yue’s black wind swallowed the blast and its fragments; Bai Yue survived, though he became smaller and less warm.
• Vera opened a door, and the group entered a blood-soaked realm filled with bizarre corpses and living monsters.
• Leticia and Vera fought creatures crawling toward the blood-red mist, while Leticia discovered a living city devouring the Vampire castle.
• Leticia was ensnared by a vision in which her sister accused her of abandoning her and killed her, but Bai Yue shattered the illusion and caught her.
• Bai Yue destroyed the tentacles covering the castle and crushed the colossal monster, revealing that Leticia had been used to break the seal.
