This story is not going to be for everyone, but I'm a little twisted and I enjoyed it. In it we follow a teenage boy Makoto who summons a demon named J, who grants him one wish. "I want to eat you". Once the deal is finished, the demon takes Makoto to hell and things get even weirder.
I will say, even though there is blood it's not as gross as you might think. The artist is extremely talented, they worked on Monster Hunter for Capcom before this manga. If you want to read something strange twisted but endearing, try MADK.
