Highschool DxD: The Second Dragon

Mitsu was an orphan until he was eleven years old, living in America. He's then adopted by a Japanese family called the Hyoudous. How will events change because of this one boy? How will he and Issei take on everybody that comes at them. Pairings are Issei x Harem and OC x Harem. Violence, blood, and swearing. Enjoy
