An: Kainda is Kah-inn-dah and Xeraphina is Sarah-fee-nah
Kainda and Kanda twins by birth. Prince and princess, princess and prince. The two were always together. Where one was the other was also. Kainda being the older twin was destined to rule their Kingdom as the Queen, and Kanda, the younger twin stood by her and supported her throughout the way of her training to become Queen.
Kanda was just a plan B to their mother, he was treated like a disgrace to the great and powerful Yuu clan. Their mother abused Kanda for being the second born, for being a boy. He was starved, beaten by whip, dragged by his hair, thrown down stairs, verbal abuse and mental abuse followed. He don't care about what people thought or said about him because of his mother, he only cared for his sister's option. Because of the way he grew up he was cold and heartless to, but sisters Kainda and Yukira( Yukira is a full ten years younger than the twins).
In the merkingdom the merpeople were separated by gender, mermaids mated other mermaids and mermen mated other merman. The merkingdom's castle was one of the only places you could find both genders of merpeople. It wasn't a law separating the merpeople, it was nature. Mermaids could only mate another mermaid and only reproduce a mermaid, and the same for mermen. And being so they natural separated themselves from each other. Also the only merman to mate a mermaid has to have royal blood, and reproduce both genders.
Under the sea, on the ocean`s floor in the kingdom of the merpeople. Allen, Lavi, Lenalee and Xeraphina play. Xeraphina and Lenalee were playing with Xera's dolls, while the twins, Lavi and Allen, played tag. Lavi was the older twin and Allen the younger twin, Xeraphina is a few meryears younger than the twins, and Lenalee was supposed to be Xeraphina's maid like her older brother Komui was to the twins, but she's more like her bestfriend than maid. Not that Lenalee complains or anything.
