Absolute Sky

Died due to an explosion, and then reincarnated into the world of tensura alongside 4 heroes of legend. he will learn that not all reincarnators start strong. [OC x harem, fluff. some trolling. NO gamer system. Multiversal travel] NOT a pokemon harem. - means that not every female will join his harem. and harem wont be huge, not sure about the limit, but definitely not more than 7 MC will not rape and no NTR.
