• Three days after the battle, the Demon Slayer Corps holds a celebratory feast, giving its members a chance to enjoy their victory together.
• The following day, Yoya announces the Corps will increase patrols and disband once they confirm no demons remain. Members may then choose their own futures, with the Ubuyashiki family offering support.
• Tetsuya and Izuna say their goodbyes to people they know, then travel to Mount Sagiri, a place tied to their earliest memories in this world.

Plot points and events

• Tetsuya takes Izuna, Madara, and Hashirama through a time-space gate to a distant timeline, where they plan to recruit that world’s Kaguya and hunt Ōtsutsuki Qi.
• Because Tetsuya previously prevented Kaguya from being sealed, this world never developed Ninshu. Instead, Hagoromo and Hamura improved farming and production, earning reputations as sages.
• Hagoromo and Hamura greet Tetsuya as their teacher for the help he gave them. He is uncomfortable with the title and asks them to call him “sir.”
• Hagoromo introduces his children, Indra and Asura. Madara and Hashirama recognize them as their own future reincarnations, prompting Madara to warn Hagoromo not to favor either child.
• Tetsuya redirects the conversation and invites this timeline’s Kaguya to join the Ōtsutsuki hunt. After hearing that the group has already defeated and refined an Ōtsutsuki into a pill, she agrees. The team sets out for the Star Sea to find Ōtsutsuki Qi.

Character developments and interactions

• Tetsuya sees that his earlier intervention has reshaped the timeline and continues building a network of Ōtsutsuki-hunting teams across multiple Shinobi Worlds.
• Hagoromo and Hamura are older and respected for helping improve ordinary people’s lives. Their gratitude toward Tetsuya is sincere, though his reaction to their formality is comic.
• Madara reacts protectively—and threateningly—to seeing young Indra, whose pride and appearance remind him of himself. He cautions Hagoromo against favoritism, though Hashirama helps defuse the tension.
• Hashirama is amused by meeting the children who will become his and Madara’s reincarnations and acts as peacemaker.
• Kaguya moves from surprise to enthusiastic agreement once she learns the hunt has already succeeded elsewhere.

Significant themes

• Fate and reincarnation: Madara wonders whether the cycle linking Indra and Asura to himself and Hashirama can be changed; Tetsuya suggests that this altered world may already have changed its course.
• The consequences of intervention: Without Kaguya’s sealing or Ninshu, this world develops along a markedly different path.
• Cooperation and progress: Practical knowledge improves society, while the expanding hunt turns former enemies into allies against the Ōtsutsuki.

Key plot points and events

• Guided by Jigen’s star map, Tetsuya’s group quickly reaches the planet where Ōtsutsuki Qi is cultivating a God Tree, a thousand years before their earlier visit.
• Jigen joins the mission, and both Kaguyas—one from each timeline—insist on fighting alongside him. After learning what Qi can do, the three plan to confront him while Tetsuya’s group guards against escape or surprises.
• The group finds Qi beside a God Tree bearing an unripe fruit. Its quality is already better than the fruit grown in the Shinobi World, explaining why Qi has stayed so long.
• The two Kaguyas ambush Qi and pull him into Amenominaka Space, where Jigen is waiting. They kill him.
• While the fight is underway, Tetsuya’s group debates what to do with the fruit. Hashirama objects to waiting for it to ripen because the planet is suffering. Tetsuya agrees to refine it immediately rather than prolong the world’s damage.
• Tetsuya begins making pills from the fruit; when Jigen brings back Qi’s corpse, Tetsuya adds it to the furnace. With Qi dead and the God Tree removed, the planet’s fate changes, and it rewards Tetsuya with a surge of natural energy.

Character developments and interactions

• Jigen has recovered much of his strength and volunteers to fight, showing eagerness to test himself. His former identity, Isshiki, prompts a brief exchange with the ancient Kaguya.
• The two Kaguyas both choose to fight and work together to take Qi by surprise. Their interaction also reveals jealousy: the Kaguya from Tetsuya’s timeline resents that he brought the other Kaguya along but had not invited her on an earlier hunt.
• Hashirama urges the group to consider the planet’s suffering rather than simply maximize the fruit’s value. He and Tetsuya discover that their Senjutsu lets them hear the planet’s distress.
• Madara and Izuna accept Hashirama’s reasoning and help protect Tetsuya while he refines the materials.
• Tetsuya leads the operation, balances the group’s competing priorities, and chooses to save the planet rather than wait for a potentially richer harvest.

Significant themes

• Compassion over exploitation: The group refuses to treat the planet solely as a source of power.
• Nature’s voice and reciprocity: Senjutsu connects Tetsuya and Hashirama to the planet’s suffering, and the planet responds to their help with natural energy.
• Cooperation across timelines: Both Kaguyas and Jigen join forces against Qi, despite personal tensions.
• The consequences of changing the past: Removing Qi and the God Tree gives the planet a chance to survive and alters its future.

Key plot points and events

• Tetsuya refines pills from Shiki’s corpse and the God Tree Fruit. His unconventional method puzzles Jigen and Madara, who assume the differences come from the fruit’s ripeness.
• Tetsuya distributes the Golden Pills to the group, including both Kaguyas, but keeps none for himself. He promises that future hunts will bring more rewards.
• Izuna suggests revisiting a planet they had once found drained by a God Tree. In the past, the planet is still alive, with a God Tree and an Ōtsutsuki guarding it.
• The two Kaguyas defeat the unknown Ōtsutsuki together, and the group turns the spoils into more Golden Pills. Jigen is surprised by how quickly the second hunt is completed.
• Tetsuya gives the timeline’s Kaguya a Star Map and asks her to scout other Ōtsutsuki locations. Concerned about facing groups alone, she requests a way to contact him; Tetsuya gives her a cross-world phone.
• Tetsuya and the others leave to hunt in another world. He plans to use wish orders to find new worlds, fulfill requests, hunt Ōtsutsuki, and distribute the resulting pills to allies and future recruits.

Character developments and interactions

• Tetsuya remains focused on building a sustainable hunting operation. He is confident in his pill-making, generous with rewards, and willing to turn Kaguya into a scout—though she recognizes the arrangement benefits him.
• Kaguya and her alternate self eagerly accept the pills and demonstrate their increased strength by defeating an Ōtsutsuki together. The local Kaguya accepts the scouting role because the rewards are valuable, but sensibly asks for backup and communication.
• Jigen moves from confusion about Tetsuya’s refining technique to enthusiasm about the rapid hunt, while Tetsuya cautions him not to expect every mission to be so easy.
• Madara and Jigen try to explain away Tetsuya’s unfamiliar method, while the Kaguyas openly marvel at the pills’ appeal.

Significant themes

• Resourcefulness and unconventional methods: Tetsuya treats pill refinement as creative rather than formula-bound.
• Cooperation through shared rewards: The group’s loyalty and strength grow as spoils are distributed among participants.
• Expansion and organization: Hunting evolves from isolated expeditions into a coordinated, cross-world system involving scouting, communication, recruits, and future missions.
• Pragmatism beneath comedy: The characters joke about efficient hunts and Shiki becoming a repeat target, but their strategy depends on careful preparation and knowing when a target may be more dangerous.
