Muto Tomu (武藤十夢?), nicknamed Tomu (とむ?), 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 Muto Tomu.
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.
- "Um, up until she was stabbed Mayu-san was using a PC, But when I looked later, the AKB48 official site was up. What in the world was she looking at? Maybe she was confirming her schedule or something."
