The way this manga treats the concept of goblins as creatures is interesting and fresh, however, I think that is the extent of the good I can say about this. The rest of the series is average at best and completely nonsensical at worst. Characters seem to not know things they absolutely should when it is convenient to provide exposition. During fight scenes the art makes the movement seem static and in general, the style is quite generic. If you are okay with a generic manga that doesn't require a lot of thinking to read and you have an extremely high suspension of disbelief thismay suit your tastes. I am trying to avoid saying any specific details, however reading just the first three chapter will give you an idea of the flaws I mentioned in the writing.
