- "Um, I played piano so I just happened to know, but at all 3 of the crime scenes, the song that was playing is Mozart's Piano Sonata No. 18. It’s a little hard to think that all 3 of them put that song into their phones together, so I think it’s unquestionably a message from the killer."

Shinozaki Ayana (篠崎彩奈?), nicknamed Ayanan (あやなん?), is part of AKB48's Research Students (Team Kenkyuusei). She is one of the primary characters in AKB48 Murder Mystery series. She was based on and was portrayed by Shinozaki Ayana.
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.
