Yukina receives a letter from her missing brother, saying he wants to meet her, but overshadowing all that is the much more immediate bomb threat involving the four department stores in Shanghai known as the Big Four. The assailant lets Yukina read his mind, regarding the location of the three remaining bombs. While Aoi and Kazura search the other two stores, Yukina and Natsume remain at the store where they are in to deal with the bombs. It is revealed that the assailant is one of Isao's men, Kuse, who is supposed to pick up Yukina and has the ability to teleport and telepathy.
