Rabbits and brothers
"Mind explaining how your Soul Slayer turned into a vegetable?" joked Byakuya.
"Was that a joke?!" said Rukia in shock.
"What do you think?" answered Byakuya.
"I think that I've walked into the weirdest dream I've ever had!" laughed Rukia.
"Think you can sleep now?" he asks. He looks down to see if she heard, only to find that she had already fallen asleep.
He picks her up and gently laid her down in his own bed, pulling the covers over her. She clutches his shirt at first, but soon relaxes. He smiles, and knows that she is sleeping peacefully at last.
He sits outside his room, his mind adrift. When he looks at the moon, he starts to think of his late wife, who also happened to be Rukia's older sister. He hears something outside and is mildly amused to see a bunny rabbit hopping along the garden. He holds back a chuckle.
"This is a first…I didn't think you actually had any brotherly love for Rukia in that cold heart of yours…" said a certain nuisance by the name of Renji.
"Why are you here?" Byakuya asks annoyed.
"I was walking by and heard Rukia laugh. Imagine my surprise to see her asleep in your lap!"
"She had a bad dream; I was merely trying to help her go back to sleep!" snorted Byakuya.
"I'm not implying anything, Captain! I'm just saying that it's unusual for you to show any affection for Rukia!"
"Renji…"
"Yes, Captain?"
"Unless you want to be the one doing all the tedious jobs the next Paperwork Day, I suggest that you stop where you are…"
"Y-y-yes, Captain Kuchiki!" said Renji nervously.
"Now what are you going to do…?" said Byakuya with a certain look in his eye.
"I'm going to leave and NEVER mention this to anyone…" said Renji quickly.
"And when are you going to do this?"
"Now! See you in the morning, Captain!" said Renji as he bolts far away from his superior.
I guess Abarai DOES have some brains under that tattooed head of his…
A certain black feline happens to overhear their conversation and silently chuckles. She leaps down from the ledge and leaves the Soul Society behind.
Byakuya stays seated for the next few hours before he goes inside to sleep himself. He gently lies next to his sister, who curls up to him in her sleep. His smile stays as he gently holds his sister and falls fast asleep himself.
When Rukia woke up, she was surprised that she was once again in her brother's arms! She stays there, and goes back to sleep for another hour.
