Exactly what you'd expect from a typical normie author—jumping on the manga bandwagon late in her career because it’s trendy and raking in big money now. It’s funny how so many Japanese folks who used to look down on manga are suddenly all about it, trying to cash in on the hype now that it’s blowing up.

I agree with everything said here. The author has the art done but the story...HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAAHAHAHAHAHAHAHHAHA!!!! Even the tits and thicc are boring.

It's a pretty good shounen, not too original or thought provoking, but it's entertaining.

Pros: The characters are wacky and likable, the art is very good, although the mangaka really wants us to know that he has a favorite female body type, and it's surprisingly funny, sometimes unintentionally.

Cons: The plot is pretty shallow and generic. The villains are the worst, they have no nuance. It's a choice between the side that wants to genocide an entire race, and the side that doesn't want to be genocided. The mangaka completely lacks the writing talent to make this a complicated choice, but boy is he trying his darndest. I burst out laughing when

a villain who just mass murdered hundreds of innocent people, including children, then desecrated their corpses, got killed, and his subordinate goes "Oh no, his daughter was just born!" Lmao

Yes, this race of people have a decent chance of going berserk and indiscriminately attacking people when put under extremely stressful, intense conditions. The solution? Let's hunt them down like wild dogs, torture, murder, and conduct inhumane experiments on them, guaranteeing they go berserk. The conflict becomes even more one-sided when you learn that the oni have already formed an organization to defend, isolate, and police themselves, making the momotaru organization even more hypocritical and redundant, erasing the necessary in "necessary evil".

Another shounen manga cliché, not bad but no good either. Read it if you have nothing to do..!
But I have to admit the artstyle is very cool!

...then maybe you'll like this manga.
Guy has quiet life, turns out he has demonic bloodline, enemy faction shows up, guy gets his ass kicked, father dies to the enemy faction, guy goes berserk, wrecks building, guy gets swooped up by friendly faction, guy gets to go to magical school. An this is the first three chapter, so not much of a spoiler.

I couldn't take more than two chapters. The MC is bland compared to Ao no Exorcist, the story is rushed compared to Ao no Exorcist, it has no heart compared to Ao no Exorcist, even the fact that things are so similar, yet so off, compared to Ao no Exorcist is such a turnoff.
Ao no Exorcist works, because Rin is a likeable guy, a goofball on better days, kicks asses on worse days, pretty humble inbetween. That is established in the first chapter, you can get a read on the kid.

Here Shiki, our MC is loud, obnoxious, and he has no depth. His relationship with his dad is shallow, he likes and collects guns, and that's all you'll have to know about him. This is the guy I have to care about? Where is the hook? Why should I care about this concept that was done way better in the past?
