Even before she was born, Kurosawa Dia was destined for greatness.
A few months into the queen's pregnancy, a small, star-shaped mark appeared on her collarbone. The mark that has imprinted itself in the minds of the denizens of Wonderland, a symbol of future royalty. A sign that, one day, she will rule as queen.
Her birth was similarly eventful. She, of course, is unable to remember anything from that time, only gaining knowledge from what she heard from other people. As her mother gave birth, dozens of citizens waited outside of the hospital, with many times more watching from home. After all, the birth of royalty is serious business.
When her first cries rang through the air, people rejoiced; there were no complications. But they weren't done quite yet. She would then be bathed in ritual water, and the used water would be boiled over a fire. Smoke billowed from the pot, and in the air, it formed a diamond long enough for people to see before vanishing completely. The diamond-the official sigil of the Rabbit Kingdom-is a sign that she will become a princess, and after that, a queen of the Rabbit Kingdom, just like her mother.
She enjoyed the first few years of her life, she really did. She came from a family of royalty, so she lived in luxury. People knew who she was, and had high expectations for her that she wished to surpass. She was enrolled in the best school there is and had many friends, all of whom admired her. She was groomed to become queen from a very young age, practicing proper manners and how to speak to other people.
She's reminded of her status every time she looks in a mirror. On her chest, right above her heart, is a diamond-shaped mark, just like the one her parents had.
As she grew older, she witnessed the birth of another future royalty for the Rabbit Kingdom, named Watanabe You. Unlike her, she came from a family of merchants, and not even one of the more well-off ones. People begin to speak in hushed whispers as they try to make sense of two future royalties in such a short time. She didn't give the rumors much thought, especially the idea that this Watanabe girl would attempt to usurp her; she'd like to see her try.
People went into even more of a frenzy when her mother became pregnant again, and the mark appeared once again. People wondered if the kingdom would be split up, or whether or not there would be multiple queens ruling at the same time. As they'd soon find out, all of these guesses were unnecessary.
She was one of the people standing outside of the hospital for her sister's birth, waiting with bated breath. When she heard her cries piercing through the air, she breathes a sigh of relief. Once again, the birth was without complication.
Things went south quickly, however, when the ritualistic bathing took place. The smoke begins rising to the air and forming a distinct shape. But unlike what she or anyone else predicted, it did not form a diamond. A heavy silence settles on the crowd as the smoke forms a pair of wings, instead. Dia can only stare in abject horror as the realization hits her.
Unlike her or her parents, her sister was not destined to lead the Rabbit Kingdom. In a cruel twist of fate, her sister was a future Fairy Royalty.
