Arc 1The Tokoyo Heir
Tokoyo Misao entered the Shin'ō Academy, drew attention by claiming the legacy of the Tokoyo Clan, and formed bonds with Rukia and his classmates. During a World of the Living exercise, a Hollow attack caused heavy casualties, leaving Misao and the surviving trainees in danger as Soul Society prepared a response.
- Tokoyo Misao arrived in Rukongai, met Rangiku Matsumoto, and traveled to the academy, where he met Rukia, Renji Abarai, and Izuru Kira.
- Misao impressed his classmates by enduring Sōsuke Aizen’s overwhelming Reiatsu, then demonstrated his skill in Kidō and Zanjutsu while training alongside Rukia and the others.
- After Rukia and Misao were excluded from the Special Excellence Training Class, Isshin Shiba learned that the Kuchiki Clan had blocked Rukia’s admission, and Rukia agreed to be adopted by the clan.
- Misao claimed to be the head of the Tokoyo Clan, prompting Yamamoto, Byakuya Kuchiki, and other nobles to investigate the clan’s history while Rukia searched the Kuchiki archives.
- Misao forced his way into the World of the Living exercise, earned permission to join, and told Kisuke Urahara that he knew how Aizen had framed him and the Hollowfied captains.
- In Karakura Town, Misao reunited with Renji, Momo Hinamori, and Izuru Kira as Hollows attacked the academy trainees, killing students and injuring Shūhei Hisagi and others.
- Misao destroyed a Hollow’s mask with his self-created Hadō after it wounded Shūhei, Renji, Kanisawa, and Aoga, while Momo and Izuru treated the injured.
- Urahara warned Soul Society that over a hundred Hollows threatened the surviving trainees, and Jūshirō Ukitake sent Kaien Shiba to request a Senkaimon and support them.
