There isn't a lot to review since this is a simple one shot, in summary it is about a boy summoning a demon.

Personally, I truly enjoyed the art style, I love how detailed it is. This detailed art style makes the atmosphere intense during the short chapter and makes the reader want to know more about it.

I actually think the idea they had to create this was really good and it makes me sad that they didn't continue with it and ended up as a simple one shot instead.

This had a lot much more potential and it could have been a really good manga.
