Reborn as Sephiroth. (THIS IS A FAN FIC!)

Newguy here. This is a FAN FIC! Similars beginings like most isekai animes and reincarnated fan fics. An otaku died saving a kid who would grow to be the earth savior and earning the otaku 5 wishes from God himself for saving the whole earth. Oh and no cultivation stuffs like that because i'm a lazy noob writer. Dual cultivation however is a different story. This is 18+ including sexs, violences and tortures but you may skip them. Mostly. I write this to fufill my "desires" so i'll write as i wish muahahahaha.
