Both are comedy works by Arakawa Hiromu, and both tend to play around with pre-existing concepts and notions.
The main characters of both of these manga have to fight against different creatures with original and cool powers. Both manga include a lot of similar humour and artwork because they are short stories created by the same mangaka. If you like one if these manga you are very likely to enjoy the other one as well. And if you like short manga with a lot of humour and some fighting then you should give these manga a try.
