Arc 1The Lieutenant’s Resolve
Miyako Amamiya joined the Thirteenth Division, mastered his Shikai, and became its lieutenant while investigating the Quincy power that had preserved his soul. After Rukia lost her powers in Karakura Town, Miyako joined the mission to find her, unaware that Aizen had approved it to draw out Kisuke Urahara.
- Miyako enrolled at Shin'ō Academy, joined the Thirteenth Division, and began training to awaken his Zanpakuto while helping Rukia confront her grief over Kaien Shiba.
- Miyako trained with Ryūken Ishida, learned Quincy techniques, awakened his Shikai, and defeated Sentarō Kotsubaki to become the Thirteenth Division lieutenant.
- Miyako accompanied Rukia to the Shiba family, where Kūkaku and Ganju accepted her apology for Kaien’s death, and later helped Rukia rebuild her friendships with Renji.
- Miyako challenged the 11th Division after its members mocked the Thirteenth Division, defeating Renji and Ikkaku before refusing to fight Kenpachi Zaraki.
- Rukia went to Karakura Town, transferred her Soul Reaper powers to Ichigo, and helped him defeat Grand Fisher after Ichigo faced the Hollow that had killed his mother.
- Miyako persuaded Ukitake and Byakuya to let him investigate Rukia’s disappearance alongside the Sixth Division’s arrest mission, then entered the World of the Living with Byakuya and Renji.
- Aizen told Gin Ichimaru that he had approved Miyako’s investigation to draw Kisuke Urahara into the matter and distract him from Soul Society.
