Improvise, Adapt, Evolve (Multiverse) (Now on DxD)

So basically this is just a SI, a concept, not a very good one, and I’m probably not gonna continue it, maybe if i get support enough but i just have ideas and they aren’t very good for long novel because you end up op pretty fast and that’s not good for novels but if you like the wishes o have an idea of how to improve them comment, i will read it… Harem Alert, i will probably have a harem for the MC
Ps English isn’t my main language
