Tokuto-kun's idle animation
His appearance is that of a violet, top-heavy geometric shape with spindly limbs, large red eyes and a strange spout of red liquid trickling from a cavity in the top of his head. This may be blood or some other liquid. Tokuto seems very preoccupied with it, scampering about his room as he watches it run down his body.
Tokuto exhibits all the normal reactions to the Knife, Cat and Stoplight effects.
When interacted with, he will stand still and tilt over to the side, pouring an endless stream of the red liquid from the top of his head onto the floor. He will not stop this until Madotsuki leaves the room and comes back later.
That the fluid in Tokuto-kun's head seems to be blood is evidenced subtly. After interacting with him, using the cat effect while he is pouring will cause the flow to speed up briefly. The bubbling rhythm sounds very similar to a beating heart, and also speeds up with the flow.
Tokuto's RoomEditTokuto's room is a strange place. It has a chair that Madotsuki can sit on and a poster on the wall depicting some strange image with unreadable text, interpreted in the fan art to the left.
The most prominent feature in the room would probably be the large pool of red liquid in the floor, which seems to be an accumulation of the same substance that Tokuto-kun produces from the cavity on his head. It has a seemingly lumpy or bubbly texture.
What this room is supposed to be or resemble - if anything at all - is very ambiguous.
One interpretation of the poster believes it shows a picture of an egg being fertilized by sperm, which would help to support some theories regarding Madotsuki's association with pregnancy. The red liquid ties into the idea of menstruation, suggesting themes of miscarriage or infertility.
