High School DxD: The Illusion of Oppai

The heroes we praise are sometimes forced to set aside their dreams so we can achieve ours. This is the lightest form of sacrifice. Born on the wrong side of a Supernatural Civil War, Issei Hyoudou is cast away from his own world and into the emptiness of the Dimensional Gap. What dangers await the boy from another world as his life flies past him without remorse?
