Fine, I'll spoil so we can start with some knowledge. A. Horvat was a young boy when Aži D broke his seal, tanks to outside help in form of an amulet made by some Mega Dude from the past that Arael vanquised eons ago. Long story short, he spirited into Andrej's backyard, weakened from his confinement and killed his parents who earned him and his younger sister a couple seconds. His sister dies in the chase by natural means, car accident. Guardian Angel, selected from the few GoTB made Angels had barely power to repel Aži, as he was rapidly getting stronger because of the amulet.

Angel spirit away the two into the DxD world and they were able to escape.

Do you need to know more or do you get why Issei can't be the hero and why Rias will experience the meaning of  the most sweetest, delicious pain, Frieza style.
