Furrata's Demon

Hello, my name is Isamu Furrata. You know I hate it when I accidentaly summon a demon. This may sound like something you see in some horrible manga synopsis. You may expect some fantasy fighting, monster bonding and some crap but nope. I just want to live an average life. I don't want some Shonen J**p or Shonen S***ay crap. It's just some random demon that I accidentaly summoned trying to get my attention.

Yeah, no.
