Arc 1The Tsunayashiro Conspiracy
Shiraishi fled the Stealth Force, found refuge in Rukongai, and became entangled in Kūkaku’s investigation into Kaien’s death and the Hollowfication Experiment. After killing Takehiko Tsunayashiro and defeating Nnoitra, he left Kūkaku to search beneath the barracks and went to help Soi Fon.
- Shiraishi fought off Soi Fon after the Central 46 ordered his execution, then escaped and found shelter with the Shiba Clan, where he witnessed Kaien’s funeral and the loss of his body.
- Shiraishi left Kūkaku’s home and traveled to West District Ten, where he killed Kenji and his companions before accepting Kawakami Saburō’s offer to hunt Hollows for pay.
- Shiraishi met Retsu Unohana and Isane while hunting a Gillian, then agreed to gather herbs with them as Aizen sent Nnoitra and Tesla to Soul Society.
- Shiraishi reunited with Kūkaku in the forest, learned her suspicions about Takehiko Tsunayashiro and Kaien’s body, and agreed to investigate the compound in exchange for help finding Dragon Lantern Fungus.
- Shiraishi infiltrated Takehiko’s compound, overheard his conversation with Soi Fon, and killed Takehiko before escaping as a Menos Grande interrupted Soi Fon’s pursuit.
- Nnoitra attacked Soi Fon and nearly killed her, but Shiraishi rescued her before confronting Nnoitra and defeating him with Steel Tempest.
- Kūkaku arrived and asked whether Nnoitra had been Takehiko’s test subject, and Shiraishi told her to search beneath the barracks before leaving to attend to Soi Fon.
