Ibitsu is a pretty solid horror manga with a premise that borders on cheesy but knows where the line is and doesn't dare cross it. This was my biggest concern going into this, and I was satisfied with the result. I wouldn't call this an amazing manga, but it doesn't have any critical flaws that make it annoying or boring.

Pros:
-it's got some good slasher moments, it you're into that sort of thing
-the character design of the loli in question is good
-it isn't too long, 15 chapters is a good amount for this manga. Not long enough to be drawn out, not short enough to be too condensed.

Cons:
-sometimes the characters do dumb things
-some of the side characters checked out of the manga in a way that i wasn't satisfied with
-generic horror tropes are present but honestly this didn't bother me too much

Overall it's a good manga and if you like horror stuff you will like this. It's worth a read. 7/10
