Arc 12The Royal Palace Gambit
Yan Si helped redirect the war to Hueco Mundo, then led a group into the Royal Palace to confront Squad Zero and pursue the Hogyoku’s power. After creating a bead from Riden’s accumulated souls, he refused to absorb it and turned toward the Soul King, still intent on his original goal.
- Yan Si examined newborn Ichigo’s immense Reishi, but stopped himself from removing the boy’s power after the Soul King warned that Hell threatened the Three Realms.
- When Yhwach invaded, Yan Si helped arrange the battle in Hueco Mundo, where Shinigami, Quincy, and Hollows fought and several captains faced the Sternritter.
- Yan Si and his allies entered the Royal Palace, where Chiziro Kenpachi fought Hikifune Kirio, Yoruichi confronted Tenjirō Kirinji, Urahara battled Senjumaru Shutara, and Yan Si killed Ōetsu Nimaiya.
- Yan Si joined Aizen’s fight against Ichibē Hyōsube and explained that he had lured Yhwach to Hueco Mundo so the Quincy king could serve as a replacement for the Soul King.
- Aizen defeated Hyōsube and went toward the Soul King, while Yan Si inscribed the names of the souls used to build Riden and fused them into a bead called Future.
- Yan Si refused Hyōsube’s demand to absorb Future, then explained his ideas about Hell and proposed a squad funeral ceremony in a Valley of Screams to conceal the Three Realms temporarily.
- Yan Si set the discussion aside and walked toward the Soul King’s Riden, declaring that his goal had never changed.
