Reincarnated in DxD with system

A man got reincarnated to the world of DxD. How he'll live in Kuoh Town, where the biggest events of Highschool DxD are going to happen? Note: This is my first time writing. I'm only doing it for fun so don't expect any quick updates. Criticism is alright specifically the constructive one. I'm not planning on making my MC too OP. But he's going to be powerful, I'm going to make sure that.
