Princess Akemi, the only daughter of the Daimyo of Kyoto, Lord Daiichi Tokunobu, convinces her father to approve of her marriage to Taigen, a young and accomplished samurai.

Reluctantly allowing Ringo to join her, Mizu arrives at a coastal town, seeking to hire a boat to reach Shindo’s island fortress.

Because of Taigen's defeat, Akemi's father plans to marry her off to the Shogun's widowed second son and will take her to Edo in five days, despite her objections.

Afterwards, Mizu knocks Taigen unconscious and leaves him with Chiaki's broken blade and a note promising to attend their duel at a later time.

To prove her competence when tasked by Madam Kaiji with pleasuring a veteran customer with erectile difficulties, she tactfully uses his interest in poetry and her proficiency in the subject to stimulate and bring him to climax.

Inside the brothel, she starts taking out the thousand claws individually, but one manages to wound Mizu, resulting in her slowly losing strength.

A narrated bunraku puppet theater play intersperses and complements the storytelling, with its female protagonist eventually transforming into an Onryō, a vengeful spirit.

In reality, Mizu is pinned down but manages to summon back her strength, turns her sword into a makeshift Naginata, and kills Hamata’s men.

Mizu follows the instructions relayed by Madam Kaji, finding the underground passageway to the castle littered with the skeletons of women and infants.

Taigen rejects Mizu's broken blade and leaves for Edo to save Akemi and warn the Shogun, vowing to kill her when he returns.

After multiple failed attempts and an epiphany that results in mending ties with Ringo, Mizu manages to recreate the metallurgy of her sword's steel but refrains from reforging it until she has slain Fowler.

Taigen finds Ringo and they decide to storm the front gate to warn the Shogun about the impending attack, which shortly ensues as Fowler’s army breaks through the castle defenses.
