Mayu is a student who is a huge fan of the idol group C.H.A, of which Harada is a member. She is a happy go lucky girl who is also a bit of a klutz. She came to the Viginti realm which is run by Ginti where Harada was waiting. Both were made to play a game of Twister that would decide their fates, and during the deadly stages of the game she learnt that her death was what would be called a freak accident, where while entering the bath she slipped on a bar of soap lying on the floor, hit her head and died instantly.
