The Chosen One (High School DxD x Avatar Issei)

Water. Earth. Fire. Air. These are the four elements that make up life as we know it. Throughout the years, several people across the world have been able to manipulate these elements. These people are known as Benders. Normally, Benders can only use one of the four elements. But, there is one individual who can use all the elements. The Avatar.

Now, a new Avatar has been reincarnated. And his name is Issei Hyoudou.
