[Tsuzemi]

"Kasai's sister, pretty much the opposite of him. Mizu crippled her wings when saving Kasai from a 'dangerous accident', causing her to be unable to fly. She then removed his memories of the accident with her psychic abilities. Mostly staying at home, Mizu enjoys a peaceful life, whilst Kasai takes the adventure for her. Mizu and Kasai are connected by an 'unknown bond'. "

Hope I didn't edit the wings too much >.<
