Kaguya Houraisan - Lunatic Princess (4) +1

Once princess of the Lunarians, she was exiled to Earth after having used the Hourai Elixir to make herself immortal. She grew to love life on Earth, so when the Lunarians sought to bring her back from exile centuries later, she hid the true Moon from the Earth. Bears a strong but fairly pointless grudge toward equally immortal Fujiwara no Mokou, and for some reason, always needs to be saved by Eirin.
