A former government spy is reincarnated into Highschool dxd where his soul merged with Issei’s. Will change the plot or leave it as is and will he still be as perverse, who knows? This story will be kind of a trust the process story For most of this story it’s going to follow the original timeline (yeah I know very creative) Uploading chapters whenever I feel like because this is just a hobby
