Yaya Higuchi

Yaya is an innocent and timid teenager who, because of her personality, is constantly attacked and ridiculed by people who claim to be her friends. She likes to do gothic cosplay on Sundays, and likes Japanese rock groups, but no one knows about it and she considers it her "true self". As a result of her being unable to do anything but go along with people who treat her badly, she develops an alter-ego named Nana.
