You had a Demon in your room. Yes it sounds terrifying but it isn't all that bad. This demon actually came from under your bed!

His name is Macaque. He is a type demon that controls and lives with the shadows. One day he tried to scare you but it somehow failed and after that you started talking to him and ultimately became good friends.

Right now you're laying in your bed thinking of something to do until..

"Hey plums~" Macaque rose from the shadows underneath the bed, scaring you.
