The Island of Desire Kisara is in a good mood after getting the key to Shu's room. On the other hand, Shu's heart is not calm as she erodes her living area, grasping the financial situation of her company and pretending to be a "shade woman". But even more problematic is the lack of living expenses for the time being. Shu finds out that her deposit, which she had relied on, is still a long way off due to miscalculation, and decides to ask Ayano to do her secondary contract work. Thus, Shu and Kisara are in charge of guarding the 25th anniversary party of Baylon City and protecting the mayor from terrorist attacks.
