Ah, so this is adaptation of a novel after all. I bet yuNS will go for it if they get their hands on some material. Or not, Konosuba duty seems to be transferred to CGT...
Meh, boring. Might as well just read Konosuba, because this is really just the same thing so far - a tsukkomi show with characters which aren't quite right in the head and just little regards to the world and story it is set in.
I think the beginning to this one is kinda weak compared to how Konosuba opens, but as long as the character interactions are fun, I'm fine with it. Although maybe the novel does a better job of it and its just the manga adaptation is a little jilted and not paced as well.
