What does one consider to be a monster? A horrible bloodsucking vampire? Frankenstein's creation? Shuichi Kagaya has a secret. Other than having great grades and being skilled at sports, he isn’t what one would call normal. In fact, Shuichi cannot even be considered human.

One fateful morning, he woke up as a monster. With brute strength, an abnormally strong sense of smell, big fluffy paws, and the depression and self-hate that comes after losing one's humanity, his life was suddenly flipped upside down. Claire Aoki, the girl he had decided to save, now holds his secret over his head. Claire is a sadistic and utterly twisted girl, with no sense of empathy toward the lives of others. Before meeting Shuichi, she was in the search of monsters, hoping to find her monster sister. Despite becoming a monster, Shuichi naively continues to hold onto his human morals, but how long can one last in this insufferable way of living?

I see a lot of people being mad about the ambiance, the pantyshots, the "hentaiborder", Claire's weird character etc...
But in the end, the manga is all about that uneasy feeling. You can either accept it and love it, or hate it. You can't rate a manga based on your preferences only. The art is great the synopsis is good (a little cliché i'll give you that) and the writing sometimes gets out of control but it's weird. Most masterpieces are weird. The mainstream ones sure are familyfriendly, but evangelion, made in abyss, ergo proxy etc... it's their aura that made them so good.

A very eh story with an interesting idea. That fails on multiple levels of some of the most basic stuff.

Monster designs tend to be creative and interesting.
First couple chapters are fairly interesting.
Some decent comedy.

~~ BAD~~
Characters don't act like regular people.

In the short span of 12 chapters this manga got my hopes up and died in my eyes, both at the hands of its fanservice. Where I once believed there isn’t a way this can flop, I am left to wonder what I liked in the first place.

Thinking back, it was probably the tension, the ambitious idea, the body horror, the nice reversal of gender tropes and shounen tropes: Gleipnir is structured as shounen, but it’s darker and more cynical, focused on the street brawl “by what means we have” philosophy. I was on board with the raunchy, sketchy art. I even enjoyed the weird ...
