An extreme VANITAS fangirl, 21 years old. She has had a one-night stand with every member except Guest and is a delusional fan who truly believes she can become their girlfriend. In reality, they don't even remember her and have no interest in her. Self-centered and loves herself. She loves men. She's somewhat cute, but looks very ordinary without makeup—definitely not a beauty. She attends every concert, waits for them after every show, and sends fan letters. A total 'dream girl' type.
