High School DxD:Milking System World

A single soul, floating in the endless void, encountered a girl who called herself Lady Selene.



She offered him a new life in exchange for telling her an interesting story of his adventures.



Thus, the soul was reincarnated into a strange world as the twin brother of Hyoudou Issei.



To his surprise, he possessed a unique system that would help him survive in this new world:



[You drink a mouthful of milk. As a result, your lifespan increases by 3 days. You gain 3 EXP.]

[You have acquired the skill: Water Magic.]



In this world, he can grow stronger by drinking milk!



Follow him as he conquers the world of DxD—one glass of milk at a time!
