A placid and soft-spoken actress who shares a boarding house with Blast and Yuri. She is older than she looks (27) and her name is often mispronounced "Myū" by Nobu. Miu wears long sleeves to hide the scars on her wrists from self-mutilation. Also, in volume 11 (the volume where she first appears), it is shown that she is a very good mahjong player (she claimed that she learnt her skills by having special training for her role in a mahjong movie as a nameless rival). She has been dating Yasu, although it is implied that their relationship was built out of convenience. (Yasu to give Nana independence and Miu because she thought Yasu was stable). She is shown to possess some jealous feelings when she sees Shion wearing the same ring Yasu had. Miu is also good friends with Hachi. When they first met on Christmas, Nana commented on how easily the two got along. Miu is also a very perceptive character, as Yasu had once commented, since she was able to predict what he was going to do. In the future, it is seen that Miu and Yasu remain together.
