Miyu is a child who somehow ventured her way into the killing game. Looking to be no older than in middle school, her personality gets on the nerves of some of the cast. According to her, she doesn't possess an Ultimate Talent, and certainly hasn't undergone the training for one. She’s just like your average little girl… How she had gotten involved in this is beyond even those involved.

Miyu’s voice is very high and should sound slightly younger than a 13 year old girl. She is very dramatic and chirpy, constantly butting her head into the adult conversations. Her enthusiastic and playful nature should play a part in most lines. However, she is slightly reserved and quiet around people she is not slightly familiar with, but she gets comfortable fast.
