I Reincarnated into High School DXD as a Random Guy

This is my first time writing fan fiction, so please forgive any small mistakes and tell me how I can improve.

This is the story about a random unknown mob guy who got reincarnated into High School DXD and how he survives this world.

Disclaimer: High School DXD and their respective characters and the cover image belong to their respective owners, I do not claim to own anything except my OC's in this story.

PS: I have only watched the anime and read some wiki entries so I won't be able the continue the story after season 4. That being said I'll do season 1 first and if people really like it than write upto season 4.
