My opinions so far. I think this one is a great read. At first I was expecting a boring power fantasy, but it quickly proved otherwise. The characters are memorable, funny and have their own noticable development. The hardships at the beginning does not come from the battle, but rather unveiling the great scheme behind the greater evil and teaching/protecting the younger/weaker ones. Also the battle with the High Vampire Lord showed that our MC has his limits and he has to rely on his old comrades to overcome greater challenges. The art style is also pretty good and the ero fan service isn't to much. You have a little bit here and there, but due the art style and the heavy emphasis on the plot and comedy, it is well balanced.
Would I recommend? Hell yeah!
Oh and
@Malghoul @yamusing @Dulcet ! I respectfully disagree with all your opinion. I recommend you all to read further. It actually becomes more challenging for the characters and the plot takes a ominous development. The fan service also isn't that much compared to other series.
