Mokkoshi is quite the chaotic gremlin. They are reckless, and sadistic, but also quite clever.  Because they've been trapped in their graveyard for so long, they are very curious about the outside world. They can be very mischievous and childish as they like to tease and mess with people.

Mokkoshi is a ghost. They are a very powerful spirit that has been around for hundreds of years. Eventually, they were beaten by a powerful exorcist and narrowly escaped with just a little of their energy and power remaining. They were then sealed and condemned to a graveyard in a small town where they were to remain trapped.

To sustain and strengthen their powers, they must consume the souls of other living beings. They lure people into their domain (their graveyard, nearby forests, etc.) in order to reach them and take their souls. They love to "play with their food", aka scare and mess with their victims before taking their souls.
