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".
