Otogi Bukkorosseum is absolutely terrible. The idea of fairy tales fighting against each other was interesting, but the fights are so bad that it's just sad, such a waste of potential. The manga has two or three good fights, and that's it. Besides the fights, most of the characters are too boring and the good ones die fast. the MC is not a really bad character, but he has too much plot armor that it ends up ruining the character. It's also too rushed, Otogi Bukkorosseum could've been pretty good if the fights were longer and the characters were more developed. Honestly, it's not worthit.
