Although Yukki suspects she hides secrets, she refuses to elaborate. Later, Yuno invites Yukki to her home, where he discovers a room with three decomposed corpses. This discovery drastically alters the future for all Future Diary owners and breaks the causality continuum, exciting Deus. Terrified, Yukki returns home to find Yuno waiting outside. Meanwhile, Minene struggles to evade police despite her diary’s escape capabilities.
