(World Building # .5)
Musing on settings#1
My hero academia is a kind of catch all world/setting ,since you can bring in basically any character/person and it can work with quirks, it will still need workshopping but what doesn't. It is similar in nature to Highschool DxD in flexibility (heh) , but where MHA is more individual based with their quirks, H DxD 's strong point is it's variable power system and hundreds or thousands of potential races and other dimensions orbiting their earth, while everyone or at least the most powerful factions decided to keep the human world intact so they can keep enjoying/preying on/or having them sustain their gods power. H DxD setting is that all myths legends or folktales are probably true somewhere ,even though it mostly focuses on the Bible's factions(angels,devils,fallen angels), then the Norse, and then Japanese YoKai.
