- Description from novelbuddy

A man reincarnates in the body of a boy who suffered a tragedy, only to realize that he is in the world of My Hero Academia. What's even stranger is that his quirk seems to have the abilities of Nen and Haki.

Another important piece of information!!!Please, do not read this story if you are unable to distinguish between an Ecchi light novel and religious events or statements related to various sacred scriptures.If that’s not the case for you and you post crap in the comments, I’ll just delete it (this is a fanfic, not a place for religious debates or discussions related to the divine word).Honestly, I didn’t want to include this in the synopsis (it makes me seem like I hate faith when I actually have religious friends), but a VERY intelligent reader managed to persuade me to explain to people the difference between an Ecchi light novel and the precious writings of human history
