Ugmons (ブサモン, Busamon) are an unusual type of Mysterious Beings created from ugly humans.
Ugmons are formerly ugly humans, who have become monsters due to bullying, or from being turned down from the opposite sex. The feelings of jealousy or inferiority turn into hatred, covering their hearts with darkness dyed with evil.
