One Big Happy Family
Disclaimer: I don't own Bleach.
WARNING: Just for the record, some "questionable" content considering the general idea of this whole thing, a "family": pseudo-incest (they're not really related, any of them, they just think they are), some alluding to sexual situations. Ichigo and Uryuu are 16 years old, while Rukia looks 16 but is obviously much, much older. The same applies to Renji.
Rukia loved her family.
She had started out alone, in a large white room. Strange people in white coats chattered anxiously around her. She remembered being frightened and angry, and fighting with them, reaching for something—Rukia didn't remember what, but it wasn't there—and she had called out for someone.
And then her "Papa" came in. There was a flash of light, and she was happy.
"You shouldn't have tried to run down the stairs, Rukia," "Papa" had admonished, ruffling her hair and smiling kindly down at her.
Rukia smiled back. "I'll be more careful. Who are you?"
"I'm your Papa. I'm here to keep you safe."
That was all that mattered. So long as she was with Papa and her "Uncles", everything was fine.
