Nopperabou Ghost ("nopperabou" is the common Japanese name for creatures without a face) looks like a typical ghost but without a face. The Nopperabou Effect can be obtained by interacting with it. It can be found in The Sewers.
Trivia
- The Nopperabou Ghost pays high resemblance to Fleebie and Follony, as well a resemblance to Youmu's phantom half and the PC-98 Bakebake (only minus the face and head piece) from the Touhou Project.
- As soon as Madotsuki has the Knife Effect equipped, the ghost starts fleeing from her.
