- "It’s still not clear to me whether Detective Maeda’s deductions are really detached from the culprit. Because one of the members is the culprit. But I don’t think the culprit is within the 13th generation. We’re always together, so I would know."
- ―Aigasa Moe's Testimonial[src]
Aigasa Moe (相笠萌?), nicknamed Moechan (もえちゃん?), 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 Aigasa Moe.
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.
After Sashiko found Rena's body, the members were called out to the hall right away. Moechan, along with Kaoru and Naana, was assigned by Mariko to report the incident with the staff on the other island, only to find out that the bridge had been destroyed.
