Despite the comments about the intro being lacking, I thought it wasn't that bad....
It wasn't so terribly nonsensical or weird, but it was a bit rough in its execution. The main character may seemed to have acted strangely (some say stupidly) in such dire situations (in the 'Orientation' intro chapters), but I thought it was understandable if you think about it. But well that's just my opinion.
In addition to the 'youkai' theme (similar to Nurarihyon no Mago, as someone mentioned below), the story seems to also focus on themes of 'fighting against those who oppress', and 'don't judge a book by it's cover'. The main character has a sad past, which is why he's so set on improving himself, change his luck, and rise over those who oppress. It's easy to misunderstand the youkai at first, but they are ultimately a mischievous bunch, and you just gotta read on to know what their real intentions were.
I gave it a 7 because although I find it to be alright, this type of manga just isn't exactly what I was looking for.
Also, can someone change the image above? It's highly misleading and not an accurate depiction of this manga imo (well, unless that's the actual manga cover...). The description is also misleading and contains spoilers (well, sort of).
All in all, I think this manga is misunderstood haha~
