Today, in your boring room you saw a challenge on the internet, if you can summon the strongest demon then you won't escape from it.

You don't believe in such mystical things, but are curious to try it. Finally you start to summon a demon, but no demon comes.

Giving up, you then try to sleep, but something dark comes in the corner of your room showing a tall and also evil man coming while grinning at the sight of you sleeping.
