- Haruto released Seisen, reached Fifth-Class Reii, and defeated the Adjuchas after protecting the wounded students.
- The survivors buried Mutsuki and attended the graduation ceremony, where Nanao and Ayaka chose the Eighth Division.
- Haruto declined offers from other divisions and joined the Thirteenth Division as its Fourth Seat under Jūshirō Ukitake.
- Haruto studied Kidō, tested his techniques, and traveled to Yoshiwara after learning Ayaka and Yuyu had gone to the World of the Living.
- Haruto found Naa Ichihara confronting Sakai Shukugo over his shipment of captive Pluses and intervened when Sakai’s toxin weakened her.
- Sakai transformed into Tsuchigumo, a monster made from ten thousand Pluses, and survived Haruto’s first Senju Kōten Taihō before Haruto struck again with six blasts.
