From the middle to the end the manga became boring for me.

A lot of "protagonist-becomes-demon" series have a minor character whose purpose is to restrain the transformation. This one, spoiler (?), doesn't do that. It would seem that the series may have ended before the plot was fulfilled, but the ending isn't too bad, so read it anyways!

Premise: 9.5/10 Plot: 9/10 Characters: 10/10 Demons: 9.5/10 Pacing: 9.5/10 Overall rating: 9.5/10

This is a Masterpiece or it could be one... The only problem it has, is a rushed ending and some characters not having some background story and development. Since they rushed/axed it, means we probably won't have a conclusion... hope we will.
Read it, it's not your average by no means. It's original and audacious, a pretty good read especially good when your bored with mainstream manga.

I noticed that its been nearly a month since the last chapter and that the last page of the most recent chapter said,"the end"
Cliffhanger?
Abruptly ended?

This one is really really good. It's still a few volume short of full story development but it is looking interesting already. Decent "no over the top" characters with a promising plot

I'll be updating this comment as I read

A series that really surprised me. The story goes sometimes too fast but it kept me in by adding new twists and objectives into the plot as arcs progress, and chapters' constructions are really good. It's feels really fresh and different, the art style is simple but efficient (the "demons" are great), and it makes me wanna read more!

This is a pretty interesting series. and I can see this becoming the next Psyren or similar manga. The characters are well thought out without being over the top (usually), although sometimes the character development can seem unrealistic. I predict one of two outcomes for this series: it shall either become the next big sleeper hit, or be finished/axed in the 3rd volume. I hope for the first one.
