Izuku, Son of Hades

The world Izuku was born to was not always this way. Many used to be born without quirks, and the Gods ruled earth from the shadows. But, all things must come to an end, because quirks quickly became known to have a side affect, which was that the women born with quirks could only have girls. As the number of quirks grew the number of men quickly fell, and at long last, only about 5% of earth was male. By that time, Gods had made a name for themselves, seeing as how quirks not only affected them, but also negated the female only birth rule, through some mysterious way. As some Gods became celebrities, others became hero's, to help and uphold there domains. Izuku, born to the God Hades, is the prince to claim all of Japan after his father relinquishes duty. But how will Izuku prove himself to his father, and finally earn the role "Ruler of the Underworld"?
