Arc 6The Silver Flash Hunt
Shiraishi and Soi Fon investigated the murders and thefts tied to Tsunayashiro Tokinada, while Aura Michibane joined the Gold Seal Unit and Aizen stole the Tsunayashiro Clan’s Fullbringer corpses. Their pursuit of Tsukikage Yagyū led them to her hideout, where Soi Fon was captured and Shiraishi activated his Bankai.
- Shiraishi and Tōshirō Hitsugaya investigated old Tenth Division cases, then joined Soi Fon at a pleasure quarter murder scene where Shiraishi traced the killer’s Reiatsu to Tsunayashiro Tokinada.
- Tokinada helped secure approval for the Gold Seal Unit, while Shiraishi watched him and Aizen began plotting to steal the Tsunayashiro Clan’s Soul King Fragment-bearing Fullbringer corpses.
- Aura Michibane won the Gold Seal Unit’s Third Seat and fought Aizen, who later impersonated Tokinada to steal the Fullbringer corpses from the clan’s secret chamber.
- After the theft, Shiraishi and Soi Fon pursued Silver Flash Tsukikage Yagyū through Rukongai and uncovered an assassination plot against Ichirō Yagyū tied to Akira Mayama.
- Soi Fon and Shiraishi found Akira Mayama dead, traced the killer’s Reiatsu to Tsukikage Yagyū, and followed her to a secret base in South District 5.
- Tsukikage Yagyū sent Kin to fight Ichirō Yagyū and imprisoned Soi Fon with a cuff that weakened her Reiatsu, while Shiraishi found her and activated his Bankai, Ignorance: Crimson Lotus Hellfire.
