So basically, the people of this town are seriously mentally ill, because of a shape gone mad/viral.

you know that one mind numbingly stupid girl who always dies first in the horror movies, because of her level of stupidity or otherwise? this manga is FULL of characters like that.

It makes not much sense. I read it yesterday, and I promptly watched something else afterwards, to try and forget it.

The story went up, then down, then back to the beginning again.
nothing went right.

in summary, if you want to read something awful, and scary, and disgusting, just for kicks, then this is probably what you read.
