Ultimate Highschool DxD

I am writing about highschool dxd. But this time the story will be different. The story goes on like in the anime and light novels. But there are major changes, a time travel in the past and change in issei's personality and strength. His true origin will be known and all the hidden secrets will be exposed. I hope you enjoy it. Thank you very much.
