Raichou Hiratsuka

平塚 雷蝶
The Head of the Supernatural Phenomenon Treatment Bureau as well as known by being its greatest traitor the Bureaus biggest mistake and by Ouka as quotThe Empires Terroristquot. She is the young butterfly girl codenamed: Electric Butterfly that cameos in almost every episode as a background character up until episode 13. At the moment it is unknown to what she has done but Ouka states that quoteven the death sentence wasnt enoughquot. She usually acts and talks innocently but is very cryptic and seems as everything she does has an ulterior motive even frightening Chika with her presence alone. A running gag is most of the time she is about to eat something sweet right before something happens. She is named after the feminist writer Raicho Hiratsuka. Source: Wikipedia.
