Youta's odd classmate whose favorite catchphrase is "this is so annoying." Aside from her listed hobbies, she also loves sleeping, and often skips classes. After learning about Touko taking on correspondence courses, she moves into the mansion, and thanks to Touko's wealth, is able to spend more money on her games.
