Shintarou Jagasaki is an average neighborhood police officer who hates his job and ordinary life. Though he acts goofy around others and plans to marry his girlfriend in the near future, Shintarou secretly fantasizes about shooting those who annoy him with a gun—much like his hero, the town's eggplant mascot, does.

The daily monotony Shintarou hates so much is interrupted when he witnesses a gruesome murder committed by a man with the face of a monster. When the creature kills his partner, Shintarou's mind is filled with the ways he has wasted his whole life. But as he accepts his impending death, he unwillingly fires a deadly projectile from the top of his fingers at the attacker.

With his arm now permanently coated in a mysterious material, Shintarou is told by a spectating owl that the now dead monster was once human. He was affected by a "Mad Xenopus," a frog-like creature that takes control of its host and changes its physical body. Shintarou initially ignores the creatures' existence. However, after one of them takes control of his soon-to-be wife, he decides to fight and eradicate the former humans to survive.

TL;DR - Edgelords rejoice, this manga a Head-empty Horror-fest, Sci-fi Shoot-em-up, Fan-service Fever dream from start to climax! er.. i mean Finish.

Jagaaaaaan is weird, and it's hard to tell whether it's trying to be a dark story similar to Ajin or Chainsaw Man, or whether it's trying to be something else. I think this is the how the authors felt as well, as there are many indications early on for setting up plots and characters that just never seem to go anywhere or fizzle out a bit (or a lot). There is still plenty to enjoy here.

The opening chapters do a great job of establishing ...

tl;dr: A manga that starts off great and pretty unique but that slowly abandons most of what made it great for something much more generic.

This manga is about Shintarou Jagasaki, a low-level police officer that is incredibly tired of the mundane and pointless life he seems to be living and sees no way out of. His ordinary life is shattered when a bunch of mysterious frogs drop from the sky and start going inside people, turning them into fractured humans. When they become overemotional, fractured humans gain superhuman powers centered around their innermost desires. For most fractured humans, this results in a complete loss of ...

Just pathetic. Imagine if you mixed a good premise with inspiration from Parasite and Gantz and simply ruined it because you are terrible at writing narratives and characters, and yet you leave your sick fetishes so visible in the story that it makes anyone embarrassed to read it. I read all those 163 chapters thinking they could still have a decent ending, but no. Just disappointing and a waste of time. I could still say the art style is good, but it feels lazy in the pacing of the series. Also, there's a character in the beginning of the story that makes everything worse, and ...
