Darth Vader x Highschool DXD

Darth Vader, a name that striked fear in the enemy, very few survive the encounter with the fearsome Dark Lord of the Sith and live to tell the tale of him. After Vader's death at the hands of his Master he found himself in a teenaged boy's body in another world that is known as Earth. How will he react to being born in a new family as well as a new chance at life? How will the 3 factions react to his abilities and his past life as a fearsome Sith Lord?

I own nothing but the character I made. Star Wars and High School DxD go to their respective creators.
