The concept here isn't that bad, the art's decent enough (though it's obvious that he's done a stint in H), there's some interesting ideas... but finishing out the first volume, I'm tossing it out because the sense of humor is just kind of unpleasant.
There's a recurring gag (if you can call it that) involving the goblins of this world, which basically look like tiny humanoid bunnies (that is to say, quite cute), 3-25cm tall, able to speak, roughly half as intelligent as humans, being repeatedly killed off because they're the pests of the world. In addition to random killings (was there really a need to add a mother and child gob begging by the wagon, followed by a splat effect, in a random panel?), the bonus chapter is all about them dying in pathetic ways. "Mama was smart. She stayed out of the city, out of the forest, away from people, on top of a cold barren mountain even when the other gobs made fun of her and we almost starved. So why did her head just explode?" Because, the protagonist was demonstrating his abilities and fired it off into a mountain, and this is evidently humor.
