Arc 1The Butterfly Mansion
Kiyohiko earned the trust of Tanjiro and the other candidates by saving them, then survived the Hashira’s judgment and was placed under Shinobu’s supervision. At the Butterfly Mansion, his concern for Shinobu’s poisoned body unsettled her, while their teasing and growing closeness continued.
- Kiyohiko rejected the Hand Demon’s offer and left to find Tanjiro, then met Zenitsu and healed several injured candidates by taking their wounds onto himself.
- Kiyohiko protected Tanjiro from the Hand Demon, helped him defeat it, and then struggled against his hunger after saving two more candidates.
- Tanjiro, Zenitsu, and the candidates Kiyohiko had healed defended him from the Ubuyashiki twins, and Kagaya ordered that he be taken to Shinobu rather than harmed.
- Shinobu questioned and tested Kiyohiko before Kagaya judged that he had proved himself by resisting Sanemi’s Marechi blood and assigned Shinobu to supervise him.
- At the Butterfly Mansion, Kiyohiko promised to kill demons for Shinobu, met Aoi, and began training with Shinobu in the dark dojo.
- Kiyohiko healed Shinobu’s cut palm by taking the wound, revealed that her poison damaged his regenerative cells, and asked why she risked her health carrying so much poison.
- Aoi told Kiyohiko that Shinobu changed after Kanae died and used poison to fight as the Insect Hashira, while Shinobu wondered whether Kiyohiko cared about her and Kanao noticed her reactions to him.
- Kiyohiko found Shinobu on the roof, teased her about her pickles and Wisteria, and began a ghost story about a kindhearted demon and a mean woman.
