Toriningen is a name given to certain characters in Yume Nikki. They have a long pointed snout for a nose that some consider to be beak-like, hence their name, meaning "bird person". Normal Toriningen will not harm Madotsuki, but those with purple eyes and what appears to be a tongue or blood coming out of their mouth teleport her to an enclosed area with no escape. (Except Medamaude and waking up.) Stabbing a normal toriningen makes her go into this "odd" state. One particular odd Toriningen behind a desk will instead change your menu color randomly.
The player character in Nasu has a similar snout.
