Nosferatusagi

Nosferatusagi is a rabbit-based Grimm created by Cure Fluffy.

Roles in Barian Remnant
It is revealed in Code Scarlett that a Nosferatusagi (or Grimm in general?) bite can cause mutations in a person's body where the victim is fine by daylight but if they are touched by moonlight, even through a window, they turn into a Nosferatusagi until the sun rises. This had happened to the character Peter Wallace, to Scarlett and Sprocket's dismay.

Other notes

 * Nosferatusagi's name is a combination of "Nosferatu" and "usagi", the Japanese word for rabbit.
 * Nosferatusagis are based on the Were-Rabbit from the Wallace and Gromit film The Curse of the Were-Rabbit. Peter Wallace, as you might have guessed, is based on the character Wallace who transforms into a Were-Rabbit during the film.
