Arc 7Aizen’s New Ally
Wang Xun split off a Hollow clone, uncovered Aizen’s experiments with Urahara, and chose to infiltrate Aizen’s circle while pursuing greater power. As Aizen drew him into the Hōgyoku research, Rangiku recovered and prepared to become a Soul Reaper, while Central 46 moved to block Wang Xun’s Kidō training.
- Wang Xun brought Rangiku Matsumoto to Retsu Unohana, who found that part of Rangiku’s soul had been taken, then tested Soul Splitting and created a Hollow clone that entered Hueco Mundo.
- Wang Xun visited Kūkaku and Nanao, then treated villagers in Rukongai whose failed Hollowfication experiments had been arranged by Aizen, who used Kyōka Suigetsu to test him and exposed him to Hōgyoku fragments.
- Wang Xun met Kisuke Urahara, identified Sōsuke Aizen as the force behind the experiments, demonstrated his controlled Hollowfication, and allied with Urahara before deciding to infiltrate Aizen’s circle.
- Wang Xun confronted Aizen during a mission, agreed with his objections to Soul Society’s system, and showed him his Hollowfication in exchange for a chance to learn the truth behind the power.
- Aizen kept Wang Xun close for his unusual abilities, while Wang Xun worked with Aizen and Kaname Tōsen on Hōgyoku experiments and rapidly learned advanced Kidō, including Raikōhō and a redesigned Reiatsu guidance technique.
- Yamada warned Wang Xun that the Tsunayashiro Clan had been asking about him, while Rangiku recovered, chose to become a Soul Reaper, and was set to enter Shin'ō Academy after healing.
- Wang Xun mastered casting two Kidō spells simultaneously with Tessai Tsukabishi, but Central 46 ordered Tessai to remove him from the Kidō Corps, and Wang Xun suspected Tsunayashiro Tokinada was behind the move before Aizen asked about his trouble.
