Ch. 431Gin
Ichimaru Gin joined Aizen in another world, where Aizen explained that local power could let Gin use his abilities and introduced him to Kyoka Suigetsu in her manifested form. As Aizen, Gin, and White Zetsu traveled back toward Konoha, Gin learned about the war, and Zetsu questioned Aizen’s plan to disguise himself before Madara.
- Gin realized he could not sense spiritual pressure, and Aizen told him the world's native power could support his Zanpakuto and Kido.
- Gin discovered that the woman beside Aizen was Kyoka Suigetsu, then held back from provoking her as she departed.
- Aizen left the valley with Gin and met White Zetsu, telling him to prepare to return to Konoha.
- On the journey, Zetsu told Gin about the Rock Ninja invasion, while Gin suspected Aizen had influenced events.
- Zetsu asked Aizen why he intended to disguise himself before Madara despite his strength.
