Arc 2Hibiki’s Rebellion and the Quincy Hunt
Ailin defeated Hibiki Hoshino’s rebellion, rose to captain of the Sixth Division, and learned that his spiritual pressure was harming Haruko Kuchiki. He joined Yoruichi and Ukitake on a mission to hunt Quincies, where the Soul Reapers attacked a village and killed its leaders.
- Haruko Kuchiki promised to testify for Ailin, while Hibiki Hoshino ordered Muramasa to infiltrate the Kuchiki Clan and kill Sōjun Kuchiki.
- After Sōjun was found dead, Urahara Kisuke traced the murder to Hibiki, and Central 46 cleared Ailin while sentencing Hibiki to exile.
- Hibiki escaped judgment, controlled other Shinigami’s Zanpakuto, and led a rebellion until Ailin defeated him with his Bankai and brought back his corpse.
- Ailin studied Kidō, resigned as Second Division Vice-Captain, became engaged to Haruko, and succeeded Ginrei Kuchiki as captain of the Sixth Division.
- Yoruichi asked Ailin to join her investigation of the Quincies, while Ginrei realized Ailin’s spiritual pressure was worsening Haruko’s health.
- Ailin accompanied Yoruichi, Ukitake, and Urahara to the Human World, where they used Hollows to expose a Quincy village and prepared an attack.
- The Quincies fought to protect the villagers, but Yoruichi, Urahara, and Ukitake killed Kurosaki Takuya, Katagiri Shuta, and Ishida Junichi, leaving the remaining Quincies unable to resist.
