Devil in DXD

I was a Normal Guy living a normal life. One day that changed when I woke to a New Body, in a Different Room and a Different World. Author Note: Its just a try so dont expect much. It will be a harem but no 18+ Chapters. I will Update minimum of 1 Chapters and Max of 2 chapters a week. Somewhat of Gary Stu and somewhat realistic. I honestly dont have much expectation for this story. I'm open to trying new Ideas but will see how it goes. It wont have perfect Grammer and such but at least wont be mixing he/her. Constructive Criticism is welcome, other I'll Ignore.
