Hmm. Here's a teaser for my KnB and KHR Crossover fic! It's basically Kuroko x OC, but the OC just happened to be his sort-of-sister. See what I mean in the upcoming chapters. It's not really incest, they won't be blood related, but that's the gist. It may get dark sooner or later, and sorry for Momoi x Kuroko fans out there, there won't be much of that here. And the characters may be OOC.

We get to see some Father!Tsuna here, though he won't be paired with any of the canon characters. This is mainly romance, since I don't have much knowledge of basketball, and I may screw the timeline a bit, but just a bit.

I hope you like it, or if not, please tell me what you think!


PROLOGUE:

January 31, 20XX

Vongola Mansion, Palermo, Sicily

Tsunayoshi Sawada, Tenth Boss of the Vongola, stood off to one side of the ballroom hall, looking at his only daughter. Said daughter was wearing a lavish looking long, silver gown which complemented her own silver hair while making her small, round, brown eyes stand out. On her hand was a glass of champagne, which, he noticed with narrowed eyes, was trembling slightly. She was surrounded by five or more good-looking men in suits, scouring for her favor, and she fended them off skillfully, as she smiled with practiced ease, looking very much like a weary princess waiting for her prince to sweep her off her feet and take her away.

Tsuna's heart went out to her. Saying a quick goodbye to the group of people surrounding him, the brown-haired Mafia Boss glided down the floor to come and save his daughter. He knew very well he wasn't the prince she was waiting for, but they both knew there was no prince crashing this party tonight.

Or anytime soon.

Holding out one gloved hand to his beloved daughter, he asked her for a dance.

The lady smiled and reached out with a hand of her own, smiling a smile way too dim for a birthday girl.

Twirling around the dance floor in their fancy gowns and suits, the daughter said to her father: "Dad, will you grant my wish now?"

The sad smile was all the answer she got.


Tokyo

In a huge bachelor style apartment, the entirety of Seirin's Basketball Club sat around a huge table laden with food: meat dishes and hamburgers from the closest fast food at the side, a huge pot of soup, some noodles, and a plain circular vanilla cake with seventeen tiny candles at the center. Laughter resounded as jokes were said and then they were singing "Happy Birthday, Kuroko" loudly and comically, swaying from side to side with huge grins on their faces.

Among them, a certain blue-eyed and blue-haired teen sat with a soft smile on his face - a rare expression - clutching a tiny half-white, half-black dog in a Seirin jersey, while sipping on a big cup of strawberry milkshake.

Times like this made his heart ache, for some reason, but he kept the resurfacing memories of home tucked in a far corner of his mind, choosing to simply enjoy the moment, because he knew that whatever his past maybe, he truly belonged here. A certain silver-haired princess may disagree, but he wasn't a prince, and anyway, she was on the other side of the world.
