Hiro Tanaka was your average otaku, who loved Reading Manga to watching anime but when God tried to save him but it backfired and he still died and as an apology, he gave Hiro a System. "Well, young Hiro as an apology for killing you I decided to let you be reborn in any world Including Anime, Movies, Books, etc. Oh yeah you can also customize a system that you want to have so good luck" * I don't own any character besides Oc* Cover Photo isn't mine if you don't like it text me.
