Arc 3The Byakugan Pursuit
Yui rescued Nai from Hyuga Feng’s laboratory, killed Ikuko, and fled Konoha with Shobue after Feng died in the collapsing lab. While Yui began Sage Mode training in Shikkotsu Forest to find a way to heal Nai, Konoha branded them rogue ninja and the arc ended as Yui and Xiao You approached the forest’s exit through poisonous smoke.
- Mito Uzumaki summoned Shobue and Yui to Konoha, where Yui slipped past the guards and searched the Hyuga Compound for Nai.
- Yui discovered that Hyuga Feng and Ikuko Hyuga were keeping Nai in a crystal sphere for Feng’s Byakugan experiment, then freed Nai and killed Ikuko.
- Yui collected the scattered Byakugan and fought Feng until Shobue arrived, but Feng’s uncontrolled beam struck Yui as the laboratory collapsed and killed him.
- Hyuga Taku blamed Yui for Feng’s death and the theft of his Byakugan, while Hiruzen Sarutobi declared Yui and Nai rogue ninja and ordered their pursuit.
- Shobue took Yui and the stabilized but unconscious Nai to Shikkotsu Forest, where she explained that Sage Mode might help heal Nai’s damaged brain.
- Yui struggled to hold senjutsu chakra underwater and decided to leave Shikkotsu Forest to seek genjutsu training, while Hiruzen reassigned Baiji to a mission against Sunagakure infiltrators.
- Yui set out through the cave with Xiao You, but purple poisonous smoke drifted toward them as they neared the exit.
