Serious version
This demon is a Shuten boy who was once the king of ghosts who led all demons. During the fight with Minamoto Yorimitsu, the soul escaped from its shell. Although the body was lost, the soul was not injured. When the main body is destroyed, the explosive power opens the door of time and space. After the demon is sucked in, in order to resist the pressure of time and space, it consumes the power of the soul. When it is transported to a plane, the soul reaches the god level and cultivates the godhead.
