The Path To Greatness (High School DxD fanfic)

When the old true God died, he did something that no one could have expected, he knew that all worlds would enter an era of chaos, but he did not want his throne to be completely taken, nor give his enemies the chance to destroy everything, so he used his remaining energy to ensure that a human being in an extremely far away realm would receive his "present", and one day this very human would take his place as the true ruler. This human turned out to be a boy called Tendo Ryutaro, and even if he doesn't know, his potential is limitless! -------------------------------------------------------------- Alright, this is an alternate universe, Hyoudou Issei does not exist! Tendo Ryutaro took his place and will have a harem composed of no more than 3! Also, don't like Rias and her Peerage? Then just don't read, don't waste my time with pointless hate comments and reviews. I'm still trying to understand the world of Highschool DxD, so, don't expect too much I might end up creating a few original events instead of simply following canon. Also, this will be a slow-paced story, don't expect mc to be the strongest right at the beginning, in fact... he might even end up being considered the weakest, but this will change given enough time when his talent really blossom.
