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.


"When we finally got 16 people together for Team 4, it became short of members again… In March when Renacchi joined, we finally had enough… As the captain, it’s a total shock. Maybe there was someone who had a problem with Team 4 assembling 16 people? Well, but if that’s the case, could that person be among the AKB members? It might be…!"
