She is one of the princess's guards. The only female in the three. She usually follows Touma's lead, but sometimes supports Haru on his plans, just so she could watch him fail and have fun. She likes video games and tonkotsu ramen. She could be in the same league as Haru when it comes to stupidity once in awhile, but most of the time, she is fairly smart and can see Touma manipulating Haru's actions.
