This is.... well.... some sort of erotic ecchi horror fantasy thriller thing.

We have a mystery, we have a mysterious powers, we have a cult, mentioned in the official description, we have ecchi/perverted elements (it is not on hentai level) and even lovecraft references.

But.

This is poorly done. The male from the main duo is being a total idiot, to the degree where it is irredeemable. Looking at the story as a whole, it is a mish mash with elements that feel forced, namely crazy antagonists, the whole cheap excuse for erotic/ecchi elements, and so on. Then there's matter of characters not being really believable. It could've been much better. The problem is not with the art, as the art is decent, it is with story writing and characters.

3/10 Story

4/10 Enjoyment
3/10 Overall.

All things considered I can't recommend it, even if you are really bored. The art is okay, but that's the only thing about this work. Then again, there are worse mangas out there.
