In the Gray Light of the Abyss - S1.E15

The protagonists return to Tokyo, but quickly find themselves on the run, having been accused of causing the explosions in Hong Kong. After discovering Dokusensha orders naming Yomiko Readman as the possessor of the final Gentleman Book, the "Book of the All Seeing Eyes," the four manage to track Yomiko down to the National Diet Library, where she is hiding with the amnesiac Nancy. Yomiko is reluctant to greet a tearful Nenene and refuses to help them, when Joker enters in force, demanding Yomiko turn over the book to him.
