Yomotsu appears before the fleeing Yuki, Yuno and Tsubaki with four hypnotised cult members dressed like him. Yomotsu explains that his Righteous Diary led him to infiltrate the Sacred Eye cult and that he intends to blow himself and Tsubaki up using Uryu's bomb. Having learned from Keigo that Yomotsu is blind, Yuno manages to find and kill him. Tsubaki then has her followers capture Yuki and Yuno, revealing her plan was to kill them, Keigo and Yomotsu all along. Due to her traumatic past as a ritual rape victim, Tsubaki wishes to attain Deus' power in order to remake the world. Yuno manages to kill the guards holding her, cut off Tsubaki's hand and hand Yuki her diary before collapsing from exhaustion. Using both diaries, Yuki manages to avoid detection, until Tsubaki tries to lure him out by announcing that her followers will rape and kill Yuno. Realising Yuno's devotion to him, Yuki gathers his courage and manages to reach Yuno on time, but Tsubaki gloats that as long as he's in sight of her followers, his actions will be predicted in her diary. Yuki throws a small ball he found earlier up in the air, causing all of Tsubaki's followers to look at it and rendering her diary useless. Yuki then throws a dart at Tsubaki's diary, and since she is missing a hand, she is unable to deflect the shot. With her diary pierced, Tsubaki vanishes and Yuki and Yuno escape. Meanwhile, Uryu, who was released by Yomotsu, gets captured by Keigo, but he eventually lets her go in return for her contact information.
