Nue Houjuu (封獣 ぬえ Hōjū Nue?)
Ability: Power to hide her true form
Location: The Night Sky of Gensokyo
Theme Song: Heian Alien
Nue is the extra stage boss, also appearing as a sphere of light in stages 4 and 6. She is a very mysterious yōkai who flies through the night sky. Despite being non-human, she was defeated by humans many times in the past, but the accounts of her appearance vary. However, those were all made up, because her form is never seen to anybody but herself. She merely enjoys frightening humans and their imagining of strange things from afar.
