Ucchii's Testimony
"Renacchi, Yuko-chan, then Mayuyu. When our chance came, it was great, but if it's our turn to be killed next, it is horrible. Our turn… Speaking of which, is there any meaning in the turn in which they were being killed?"

Manga Version

Chapter 1

All 89 members of AKB48 went to a duplex island owned by one of Akimoto Yasushi's friends for a CM Shoot. After their first day shoot was over, they went to their designated resthouse on the other island. It was assumed that she heard that Kato Rena was missing and was shocked to learn that the scream they heard was from Sashiko finding the girl's lifeless body in the dining hall.
