Still a very new manga, so far 17 chapters and 2 one-shots.
The story is very interesting and enjoyable even thought the story still building up to something, so far it's introducing the characters and a bit of action. I love the art style and how the demons/spirits looks so far, you can really see the dedication of the mangaka and omg I already have a new waifu (if you know you know LOL)

I give an overall 8 because even though it doesn't have that many chapters, it's really interesting plot, can't wait to see how the story develops. (i'm bad a t english xoxo)
