Izumo Momo is a tall girl of around 15–16 years of age, and has long pink hair and red eyes. She is rather clumsy, but is shown to have super strength, once breaking a katana with two fingers accidentally. She is a nurse, the helper of Narutaki Soutaro. She is the more responsible one, although she is a bit of an idiot. She summons the medical weapons in their medical book, Kaitai Shinsho, but usually summons the Tsukikumo (Moon Cloud).
