Hikari

The last White Dragon and the last dragon alive, Draco become her husband using the Dragobond (a contractual marriage between two Dragons) because Draco is also a Black Dragon and the last Black Dragon.

White Dragons can only be female and Black Dragons can only be male. As soon as a white and black dragon meet they cannot escape their desire and become dragonmates (the female can only have only 1 husband).

Pregnant twice and laid two eggs, one with the lineage of a white / black dragon and Ultimate Sunt and the other is Human but slightly modified by Hikari as a Human cannot normally be born from an egg.
