Key plot points and events

• The day after acquiring the sword-technique scroll, Yui discovers that its tiny letters appear to be miniature swordsmen when viewed without her Byakugan. Their movements form a practice routine; following them with Hakutaku makes her sword swings smoother and stronger.
• At the General’s Residence, the bandaged Rengo reports that Iinaka’s white Famous Blade has been taken by a powerful woman—Yui—and that neither he nor his brother could defeat her. The General is furious and considers killing Iinaka, but Rengo persuades him that protecting the renowned swordsmith will better serve his prestige.
• Rengo reassures the General that Yui is a ninja, not a samurai, and supposedly poses no political threat. They decide to hold a ceremony for the other completed Famous Blade.
• Three days later, Yui hears that the ceremony is taking place in Iron City. She learns that Hakutaku debuted four days earlier and was already identified as a white Famous Blade owned by a woman. Yui invites Nai to attend, saying they will likely leave the Land of Iron afterward.

• Rengo reports his defeat to the General, then restrains him and argues against killing Iinaka.
• Yui listens to townspeople discuss the ceremonies, shares what she learns with Nai, and leads her toward the General’s Residence.

• The crowd celebrates the sword, while samurai admire it but refrain from fighting over it because a Sword Saint is present.
• From a nearby rooftop, Yui watches the unveiling with Nai Hyuga. She recognizes the blades’ names and quietly leaves, apparently accepting that she may never see Iinaka again.
• Iinaka notices the two women departing and hopes Blackwater will earn renown in the hands of the woman associated with the Evil Ghost Mask.

• Xiaocui insults them as they go. Nai, furious, secretly fires an almost invisible ice needle into Xiaocui’s neck, though Xiaocui does not realize what happened.
• Yui suggests they find a hot spring in the wilderness instead. A shadowy man who had been watching them overhears the idea.

Character developments and interactions

• Yui recognizes the symbol as the mark associated with Jashin and suspects a ritual is taking place. The victims’ ages suggest the cult’s violence may explain why the nearby village was so sparsely populated.
• A masked group arrives carrying kidnapped children. Their leader declares them followers of Jashin and orders his followers to attack Yui and Nai, intending to use them as sacrifices.
• Yui warns Nai not to let the cultists’ weapons wound her, hinting that they may have unusual properties. Nai elects to fight the group herself, both to protect the children and to test her newly developed ninjutsu.

Key plot points and events

• Nai Hyuga’s uncontrolled ice-based Ninjutsu freezes the Jashin Cultists. She later shatters the ice statues without spilling blood, but the technique also damages her mask.
• Nai gives up wearing a mask. Yui follows suit, deciding that her altered appearance makes concealment largely pointless and that a mask can interfere with Ninjutsu.
• The two find several bound children who were likely taken for cult experiments. They free them and begin waking them, intending to let them return home.
• Yui senses a voice coming from the enormous Cursed Seal on the mountain wall. It claims to be an evil god, demands blood, and offers eternal immortality in exchange for help awakening.
• The voice attacks Yui’s mind and causes her to bleed from her eyes, ears, nose, and mouth. She uses Sage Mode to repel it, and the voice retreats as the seal darkens.

• Yui directs Nai to see the children home while she investigates the seal. When Yui’s power surges, Nai notices and moves toward her, concerned.

Plot points and events

• A blood-red cocoon traps Yui. Nai tries to pull her free and attack it with ice spikes, but neither effort works.
• Inside the cocoon, Yui confronts the Evil God, whose teasing manner initially makes her seem more ridiculous than threatening. Yui discovers that senjutsu-infused spiritual energy can hurt her and uses it to demand answers.
• The Evil God appears as a small, bubble-like creature. Yui toys with her, letting her guard down and briefly thinking of her as an amusing companion.
• The Evil God exploits that lapse, bites Yui’s neck, and places her under the influence of the Evil God’s Cursed Seal. She claims Yui is “one of her kind,” calls her a chosen follower, and says the seal will continue to grant her power.
• The blood-red space collapses, releasing Yui. Nai rushes to her side and recognizes the mark as the Evil God’s Cursed Seal. Yui treats the painful bite with senjutsu chakra.

Character developments and interactions

• Yui shows confidence and resourcefulness by resisting the Evil God with senjutsu, but her curiosity and amusement leave her vulnerable. She recognizes that her emotions were manipulated and regrets underestimating her opponent.
• Nai is fiercely protective: she tries to break the cocoon and, once Yui is free, urgently checks her for injuries and searches for whoever attacked her.
• Yui and the Evil God shift from a hostile interrogation to a deceptive game. The Evil God’s playful teasing conceals her power and intent; she ultimately turns Yui’s mockery and lowered guard against her.

• Power with a cost: The Cursed Seal promises strength while binding Yui to the Evil God’s will.

Key plot points and events

• After the pain from the mark eases, Yui’s Sage Mode deactivates. She confirms that the burning mark on her neck is a Cursed Seal and admits she does not know what it may do.
• To protect Yui, she summons Xiao You and asks whether it can seal the mark. Xiao You recognizes it as the Cursed Seal of Evil God Nami, but is too frightened to help.
• Xiao You recalls that Nami once descended into the world through an avatar, drained the blood of living beings to grow stronger, and searched for a man who had betrayed her. Xiao You’s clan eventually sealed that avatar.
• The Cursed Seal gradually transforms its bearer, increasing their power and potentially granting immortality. Once the bearer is sufficiently altered, Nami can possess them and control their body—a process that may take decades.
• Xiao You says it cannot seal the mark with its current abilities, though studying additional Sealing Jutsu might make it possible. Nai urges Yui to leave immediately for the Land of Whirlpools to seek such techniques; Yui says there is time, but Nai remains worried that the seal may have changed.

Character developments and interactions

• Xiao You reveals frightening inherited memories and recognizes the danger, but feels guilty about being unable to seal Yui’s mark.

• When Yui reveals their destination is the Land of Whirlpools, Yuri says she ran away from there. Nai becomes suspicious because Yuri had just claimed to be homeless.

Plot points and events

• Mito and Yui discuss whether Yui should learn sealing techniques; Mito says the decision ultimately depends on Xiao You’s consent.
• The Nine-Tails summons Mito into her inner world and explains that, during Yui’s visit three days earlier, he sensed a terrifying, non-chakra consciousness attached to her neck. He believes she may be seeking sealing techniques to contain it.
• The Nine-Tails first urges Mito to kill Yui, offering her control of his power and promising to cooperate with a future jinchūriki. Mito refuses to act without verifying the danger and will not harm Yui merely because of what may possess her.
• He then proposes a compromise: Mito can combine his chakra with her sealing jutsu to seal the presence. Mito accepts, seeing this as a safer way to help Yui and gain her trust.
• After Mito leaves, the Nine-Tails admits to himself how deeply afraid he is. He believes the presence may surpass even the combined tailed beasts, the Sage of Six Paths, and Kaguya.

Character developments and interactions

• Mito shows caution and compassion: despite the Nine-Tails’ tempting offer, she refuses to kill Yui on unverified claims. She is willing to help seal the threat instead.
• The Nine-Tails reveals unusual fear and desperation. He tries to manipulate Mito with promises, then lowers his demand when she refuses. His private reflections suggest the threat is far beyond anything he has encountered.
• Mito and the Nine-Tails negotiate tensely: he pushes for Yui’s death, while she challenges his motives and insists on a less harmful solution.
• Yui does not appear directly in the inner-world conversation, but the discussion reframes her sealing studies as potentially connected to a dangerous force attached to her.

Significant themes

• Power and fear: Even the Nine-Tails can be overwhelmed by a force he cannot explain.
• Trust and verification: Mito refuses to make a life-or-death decision based solely on the Nine-Tails’ account.
• Compassion versus expediency: Rather than eliminate Yui, Mito chooses containment, preserving the possibility of helping her.
• Hidden identity and inheritance: The Nine-Tails suspects Yui has a lineage linked to the Sage of Six Paths, with her Byakugan and horns hinting at a transformation or return to her ancestry.

Key plot points and events

• Yui notices Mito abruptly close her eyes and suspects she is communicating with the Nine-Tails. Mito has indeed learned from the fox that Yui’s red Cursed Seal carries a dangerous “evil will,” though Mito cannot sense anything unusual about it at first.
• Mito deduces that Yui came to study Sealing Jutsu so she can suppress the seal. She offers to use the Nine-Tails’ chakra together with sealing techniques to help, and Yui accepts in principle—but insists they wait until Xiao You wakes, since she does not want to attempt anything without the creature’s guidance.
• Mito asks to inspect the seal. When she moves close, she becomes dizzy, and the seal’s image disappears from her memory within moments. The experience frightens her and makes her understand why the Nine-Tails feared it.
• Kazumi arrives in distress with urgent news: enemy ninja have forced their way in, and the clan leader is fighting them. Mito realizes the attack has begun.

Character developments and interactions

• Yui is eager for answers about the seal and cautiously hopeful that the Nine-Tails’ chakra can help. She warns Mito not to touch it and shows concern when Mito becomes dizzy.
• Mito shifts from skeptical curiosity to genuine alarm after the seal affects her perception and erases her memory of its appearance. She also trusts Yui enough to offer help, while keeping her identity as Konoha’s jinchūriki secret.
• Kazumi’s panicked arrival abruptly interrupts the discussion and signals an immediate crisis.
• Yui and Mito share a guarded but cooperative exchange: Yui protects Mito from the seal’s danger, while Mito offers a possible way to suppress it.

Significant themes

• Hidden danger and unreliable perception: The seal seems harmless from a distance, yet close inspection causes dizziness and memory loss.
• Trust and secrecy: Mito asks Yui to keep her connection to the Nine-Tails confidential, and Yui agrees.
• Knowledge and caution: Yui’s insistence on waiting for Xiao You shows that even a promising solution should not be attempted without understanding the seal.
• Crisis interrupting investigation: Just as Mito begins to grasp the seal’s threat, an invasion forces attention toward immediate danger.

Plot points and events

• Mito worries that Konoha’s promised support has not arrived and wonders whether the ANBU messenger was intercepted. Kazumi confirms the attackers wear no village insignia and uniform-looking clothes, so their identities are concealed. Mito heads out to question them and asks about the forces and Tsunade.
• Yui stays behind as Xiao You finishes learning Uzumaki sealing techniques. Xiao You discovers that learning them improves its overall strength—and slightly increases its chakra reserves—but expects the benefit to diminish as it grows stronger.
• Xiao You identifies the Evil Sealing Method as a good way to suppress the Evil God’s cursed seal. Though eager to try it, it agrees to wait so Mito can contribute her sealing knowledge and help make the seal more secure.
• Hearing battle sounds, Yui goes outside with Xiao You and Hakutaku. Nai Hyuga reports that the invaders are powerful Water Release users who have cloaked the street in mist. Yui suspects they may be from the Hidden Mist Village, though the apparent force she recalls seeing is far larger than the group currently encountered.
• Yui and Nai prepare to join the defense, honoring their promise to help the Land of Whirlpools survive the attack.

Character developments and interactions

• Mito is anxious about the missing Konoha aid but shifts from worrying to taking action, seeking information about the attackers.
• Xiao You gains confidence in the Uzumaki sealing arts and recognizes both their combat utility and their effect on its own strength. It trusts Yui’s judgment to delay sealing the cursed mark until Mito can assist.
• Yui shows caution in choosing a stronger, collaborative seal rather than rushing, then quickly turns her attention to the invasion.
• Nai remains watchful with her Byakugan and seeks Yui’s direction; Yui responds decisively and commits them to the fight.

Significant themes

• Cooperation and shared expertise: Combining Xiao You’s bloodline power with Mito’s knowledge may produce a safer, stronger seal.
• Caution versus urgency: Yui avoids a premature sealing attempt even as an immediate battle draws near.
• Uncertainty and preparedness: The attackers conceal their identities, and their strength and numbers remain unclear.
