Idea to story. Clan Abilities (DXD) are DNA / Life Code mutations. Could he not inspire a change of race dxd (Evil Pieces) is a manipulation of the code of life. Change of race from one race to another. Akeno remained a Fallen Angel despite her race change. She gained the magic of devils and their other qualities (strengths and weaknesses). If he figured it out, he would have another option. Worse, but CAN help you understand the code. If he had come to this world it would be a GREAT opportunity. Divine gifts, clan traits. DRAGON GOD (ophis, loli waifu / legal loli). New types of magic! He could even get a new form of immortality. First generation angels and fallen. It would be enough to compare them later with the descendant of the fallen (I don't know if this is a fan-made statement) but the second-generation fallen is only long-lived, he can die of old age. If he had made a mix of all races dxd how much potential would this breed have?
