- "No matter what happens I want to stay positive, I thought, but I caved to depression after this time’s incident after all. Oh yeah, being that 3 people were killed, I think there are people who are more depressed. Have you already interviewed them?"
- ―Chikano Rina's Testimony[src]
Chikano Rina (近野莉菜?), nicknamed Chikariina (チカリーナ?), is a member of AKB48's Team B. She is one of the primary characters in AKB48 Murder Mystery series. She is based on and was portrayed by Chikano Rina.
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.
