Arc 4Kaidō and Kidō Studies
After the confrontation with Tōsen, Wang Xun deepened his ties to the Fourth Division and Kidō Corps while helping Soi Fon develop Shunkō. His rapid progress drew attention from Unohana, Tessai, and Aizen as disappearances and attacks in Rukongai continued to raise suspicions.
- Kisuke Urahara interrupted Kaname Tōsen’s clash with Wang Xun and took the unconscious Amamiya Shin into Stealth Force custody, while Wang Xun stayed with the poisoned Soi Fon and carried her to the Fourth Division for treatment.
- Kensei Muguruma apologized for Tōsen’s conduct and accepted Wang Xun’s request to prevent similar incidents, while Wang Xun helped Soi Fon discover a way to gather Reiatsu around her shoulders and back as she developed Shunkō.
- Yoruichi arranged for Wang Xun to study Kaidō with the Fourth Division, where Kiyōnosuke Yamada watched him rapidly master treatment techniques and reach the level of higher-ranking Seated Officers.
- Wang Xun visited the Kidō Corps with Urahara, absorbed insights into Dual Incantation, and formed a stable spiral of two kinds of Reiatsu, leading Tessai Tsukabishi to offer him regular study as an external trainee.
- Unohana began teaching Wang Xun personally, and he assisted her in stabilizing a critically injured Fourth Division officer before meeting Lieutenant Aizen, who later told Tōsen not to investigate Wang Xun further.
- Nanao missed Wang Xun during her studies, while Aizen and Shinji Hirako investigated an Adjuchas whose Reiatsu contained traces of Shinigami Reishi, and Aizen secretly instructed Tōsen to focus on the Hollow and the Hōgyoku.
- Unohana considered Wang Xun as a possible replacement for Yamada, but Isane Kotetsu’s invitation to transfer to the Fourth Division left his future assignment unresolved as Wang Xun continued studying in both divisions.
- After hearing reports of increased attacks and disappearances in Rukongai, Wang Xun suspected Aizen might be involved, then demonstrated a stable Dual Incantation at the Kidō Corps and accepted Tessai’s offer to teach him what came next.
