What happens when an experienced transmigrator gets reborn in the world of My Hero Academia ? (Slow paced and has an entire volume preceding the cannon, so you are warned beforehand.) . (Read at least the first 8 chapters before giving a judgment) "NOTE: This is my first fanfic (or first literary work for that matter) so there can be many mistakes (which will improve practice makes perfect after all) as such I request anyone willing to review or comment to refrain from abusive statements (cause I am going to just remove them) but any constructive criticism and feedback are always welcomed."
