Review Detail of Kenz6y1 in In MHA as Pain

the concept is nice like any other type of "reincarnated in (....) as (....) FF" but please where the fudge pain has all thoose kekkei genkai, where the fugde did he learn 8 gate, please be realistic open pain fandom to see his chakra nature and then you can start from there build your own jutsu. and the stories so far is pretty meh, just the skeleton of the narration no detail no explanation
