a little about the character:

It appears most often when he feels that the nuns have thought of something sinful, he completely clouds their minds and gives free rein to all the sins that may be (sex, murder, etc.). After a short period of time, the nuns die and immediately go to hell, and Kolya continues to wait for new prey. Each death gives him more and more strength, but if suddenly the prey refuses to commit sins, he begins to weaken and leave the person.

Most often he comes to people in the image of the holy father, but in fishnet tights on his legs.
The wings and tail have great sensitivity.
The eyes are completely white, have no iris and pupils, but this does not prevent him from seeing everything.
