Mint Blancmanche

ミント・ブラマンシュ

An intelligent blue-haired girl who loves cosplay, particularly wearing full body costumes but will never, ever be seen by her friends while wearing them (unless it's work-related). Her family is wealthy and she sometimes comes off snobbish (and has a cruel streak), but she normally has a sincere, distinguished politeness in her voice when in conversations with others. She, along with the rest of her family and the family pet, has a pair of white rabbit ear-like appendages just above her normal ears that twitch, rise or droop depending on her feelings.
