Arc 2The Bount Settlement
Jun survived a deadly expedition in Hueco Mundo, returned to Soul Society, and began investigating the Bount with Isuzu. After gathering hundreds of Bount and founding a hidden town, Jun faced the problem of how to sustain them and protect them from Soul Reapers and Hollows.
- Jun helped expose and end the conflict between the Shiba and Shihoin Clans, but the fighting cost hundreds of lives and led to the Shiba Clan losing its noble status.
- Jun mentored Kōga Tatara at Shin'ō Academy, accepted an expedition to Hueco Mundo, and led a team into the Forest of Menos under Kensei Muguruma.
- A Rhinoceros Beetle Hollow drove the expedition toward the Senkaimon, and Jun stayed behind to help the others escape before encountering Coyote Starrk and Lilynette Gingerbuck.
- Jun lived with Starrk and Lilynette in Hueco Mundo, studied Hollows, and arranged for Starrk to injure and send him back through a spatial rift.
- Yamada Taiyū and Akiyama Eiji rescued Jun, and he recovered in Soul Society while Isuzu and Aizen learned how he had survived.
- Jun and Isuzu traveled to the World of the Living, found the Bount Koinu, and learned about the suffering he had endured.
- Jun renamed Koinu Minamijima Inosuke and joined Isuzu in gathering 372 Bount, including Kariya Jin, to establish a town on Shikoku.
- Jun promised to teach the Bount and realized they needed food and protection, then discovered they could gain Spiritual Power by eating Hollows and began devising a new plan.
