I've read 15 chapters and so far this seems to be a middle of the road fantasy story. A solid, above average 6.

So far the story did some basic, but much welcome world building. I got a general sense where the story is going, but nothing concrete. However, it isn't really in a hurry to get anywhere interesting. Since it is just the beginning of the story I don't want to be too judgmental.

Something I wasn't satisfied with is the characters. The MC is generic but other than that I don't particularly have any problems with him. However, his "servants" Tomoe and Mio really need some fleshing out because so far, they seem to be more defined by the MC, than having their own personality. I mean... they even get their names from him. What is this if not the ultimate power fantasy?

Maybe it is early to make an overall judgment, but my first impressions are as follows: The manga is a simplistic but entertaining read, it really requires some polish in the story and character department, and a bigger story arc that kicks the plot into motion would be nice.
