Arc 1Academy Prodigy
Kyōsuke Kuchiki entered Shin'ō Academy, displayed extraordinary Kidō and combat abilities, and helped Gin Ichimaru pursue revenge against Sōsuke Aizen. After Kyōsuke defeated an Adjuchas and dozens of Gillians during a Hollow attack, the captains recognized his strength, and he reached graduation with his choice of division still ahead.
- Kyōsuke Kuchiki enrolled at Shin'ō Academy, where his Third-Class Rei'i stunned the observers and earned him a place in Special Class 1 alongside Gin Ichimaru.
- Kyōsuke demonstrated powerful, unfamiliar Kidō and awakened Dijiang's Shikai, while declining Sōsuke Aizen's invitation to join the Fifth Division and agreeing to help Gin gather information on Aizen.
- Kyōsuke won the seated officer competition with his golden barriers and Tenfold Thunder Path, taking First Seat as Gin took Second Seat.
- During Konsō training in Karakura Town, Kyōsuke killed a Gillian and protected the trainees as more Gillians and an Adjuchas emerged from black rifts.
- Kyōsuke battled the Adjuchas and its Gillian reinforcements, then killed them with a twofold Kidō attack as Gin led the surviving trainees to safety.
- Kyōsuke destroyed the Adjuchas's remains before Sōsuke Aizen could study them, and Kisuke Urahara later concluded that Kyōsuke had defeated dozens of Gillians and possessed Captain-level strength.
- The captains discussed recruiting Kyōsuke, while Kyōsuke earned top marks, advised Gin to target the Fifth Division's fraudulent Third Seat, and planned to build his own force.
- Byakuya Kuchiki assured Kyōsuke that the Kuchiki Clan would support his division choice, and Kyōsuke arrived at graduation where Sōsuke Aizen congratulated him and Shinji Hirako recognized him.
