Interconnected Dimensions: Issei's New Journey

Lucas, a 21-year-old boy, dies in an accident and is reincarnated in the body of Issei Hyoudou at the age of 8, before the events of High School DxD. In addition to inheriting Issei's life, he discovers that he has a unique ability: the ability to travel to parallel worlds in a mana accident, where he can explore realities in other universes - each one filled with new challenges, dangers and allies. As he tries to understand what is happening, Lucas realizes that his power is not only a blessing, but also a key to an even greater destiny, the balance of the worlds.
