Arc 9The Hollowfication Crisis
Yan Si uncovered the Tsunayashiro clan’s secret and gathered Soul King Fragments, while Aizen and Kyōka drove events toward Hollowfication and framed Yan Si and Urahara. The arc left Yan Si fighting the newly Hollowfied Visored in Zhonghe as Hirako watched.
- Aizen infiltrated the Research and Development Bureau disguised as Urahara, but Mayuri exposed him and led him toward a hidden passage.
- Yan Si returned to the Ninth Division, prepared a single-use Soul Jade, and encountered the aftermath of Kaien’s fight with Aaroniero during patrol.
- Aizen and Tōsen used Soul King power and Hollow energy to awaken Kyōka, who escaped his coffin and defeated Byakuya before fleeing.
- Yan Si entered the Tsunayashiro Safe House, where Tokinada revealed the nobles’ role in dismembering the Soul King and planned to replace him with Kūgo Ginjō.
- Yan Si killed Tokinada, collected Soul King Fragments, and escaped as Tokinada’s attempt to flee through a Senkaimon ended in an explosion.
- Mayuri made Consumable Soul Jades, and Kensei and Kyunnan Shiro swallowed them and became Hollowfied while Aizen, Tōsen, and Kyōka observed.
- Tōsen attacked the Visored, leaving them gravely wounded, and Urahara used the Hogyoku to stabilize them while Yan Si departed.
- Central 46 accused Yan Si of conspiring with Urahara, but Yan Si sensed the corpses and confronted Kyōka, then went to Zhonghe as the Visored awakened and attacked him.
