Crosso and Dreamy.

Crosso first fell in love with the princess when sunlight fell on Dreamy's hair, illuminating her appearance with an even stronger light, though Dreamy... Without it, the skeleton is bright, especially her soul. Her only family member was a sister named Nightmet, and she was fine, but Nightmet eventually began to view Dreamy as her enemy when she abruptly changed her personality from light to dark and began to desire a second throne in the south of Dreamtail. Since Dreamy already rules the southern throne, the price of seizing this throne is Dreamy's life, and Nightmet apparently wasn't satisfied with the fact that she already rules the northern side of Dreamtail and is the lady and boss of her own all-female villain gang , the Bad Girls.

Crosso is the biological Empress of X-Tale, named X-Gastilda, but she doesn't take kindly to the plans of the material world, as it seeks to conquer the other AUs. Crosso has a full younger sister named X-Patricia and two younger half-sisters, created through X-Gastilda's experiments. Afterward, she took two dolls into her hands, each life-sized, like human children, given birth to at a more conscious age. Their names are X-Chara, who agrees with Crosso about her creator, and X-Frisk, who seems to be with them but at the same time obeys her creator in everything, as she gave her and X-Chara life, no matter how good or bad she was as a mother to them. After Crosso left this world, she became a hitman for Nightmet, a gang member, but later left them and Nightmet as well, as Nightmet holds the position of lady boss there. Afterward, Crosso began serving Princess Dreamy. Besides her and her family, Crosso has a best friend named Epica, who is also a skeleton and the daughter of the ruler of Epictail, a world X-Tail has an alliance with. The ruler of Epictail is named Epic-Gastilda.
