Hidden Mercenary: Highschool DxD x Male Reader

Y/N L/N. A feared human from all factions of the supernatural. Well, mostly Angels and Fallen Angels. Why? Because he despises them. For what? Killing his entire family at a young age. He was disgusted by them, but his parents left two things. Two sacred gears. More specifically, a dark sword and a gun. Y/N already knew what to do, use them to kill any fallen angel or angel that gets in his way.
