Isurugi Amane♀

Hayato's adopted older sister, who was raised with him by her grandfather. When she is with Hayato, she is bright and loving (as well as being clingy). However, when he isn't around, she is all business, acting professional and cold to most. She is a master of youjutsu (the art of using spellcraft directly in combat and enhancing the body) who wields a katana in battle.
