In Immaterial and Missing Power Hourai was one of Alice's 2nd level spell cards. She had the exact same sprite and effect as Shanghai (the 1st level spell card of the same type), only much stronger.
(While part of Alice's portrait during conversation, being defeated.) She has blond hair. She wears a long dark purple dress with a white apron and white shoulders, and matching dark purple shoes. There is a large red bow in her hair and a smaller matching bow around her neck. Very similar to Shanghai in the game, only her eyes aren't seen and her neck is hanged by a rope.
- She so far has no known relation to either the Hourai Elixir or Kaguya Houraisan, nor even to Fujiwara no Mokou, who also has a spellcard called "Hourai Doll". It is most likely a reference to the aforementioned island paradise of Hourai, since Alice's other spell cards (such as Foggy London Dolls or Red-haired Dutch Dolls) are references to countries or cities.
- As with Shanghai, Hourai is canonically a class of doll rather than a name for one individual doll, and multiple Hourai dolls are seen during its spell card in Perfect Cherry Blossom.
