The FC Demon is an Effect-giving NPC found in the FC World that gives Madotsuki the Demon Effect. They have dark pink skin, narrowed black eyes, lilac hair, pink horns and lilac/black clothing that includes a checkered top.


They can be encountered in FC World B. There is a 1-in-6 chance that they will appear in the place which has its entrance surrounded by six pyramids. However, they will always appear if Madotsuki has the Demon effect equipped. They teleport Madotsuki to the FC Basement, to their side.

In the FC Demon's Room in FC Basement, the FC Demon is surrounded by Kinoko-san, who also guard their door. The Demon effect can be acquired by interacting with the FC Demon. When interacting with Madotsuki, the FC Demon makes a sound that sounds similar to a smooch. They always will turn around to look at Madotsuki when interacted with.


  • While the FC Demons themselves do not particularly resemble the japanese folklore creature Oni, the Demon effect they give out transforms Madotsuki into strongly resembling said creature.
  • While in the FC House an adventurous tune is heard, the background music in the FC Demon's room is calmer and more cheerful, and features sounds that are akin to birds chirping. In the official CD, the described track has thus been adeptly named "The Bird is outside the house and the Demon is inside the house".
