A mysterious girl with an unknown past, titled only as the Legendary Tae Yamada. She is the only one of the girls who has not fully regained consciousness, and so has remained a mindless zombie. As such, Tae is unpredictable and driven by pure instinct, doing things such as biting at the other members and launching herself at the crowd. However, she does seem to have some semblance of awareness, being able to at least understand the members to some degree and be cooperative enough to participate in the practices and performances.
