Although I originally wanted this to be one chapter, I decided to do more.
Of course, it will have a lot of Ichi/Ruki in it, but Byakuya/Hisana will be the main focus.
It will also go to Rukia's view of things at times.
"Forgive me, brother. But Lady Yoruichi is here to see you on urgent business." Yoruichi? Nothing was ever business with Yoruichi. "Thank you, Rukia. You are dismissed." Rukia bowed and quickly exited. She really was becoming a proper lady- because of my training.
Interrupting my thoughts, Yoruichi came in without knocking, her arms crossed tightly over her chest. "Byakuya," she growled, "It's about Rukia." This immediately caught my attention. "Rukia? Has she been... misbehaving?" She snorted, rolling her catlike yellow eyes. "Hardly. She's an angel."
"Well- please address the matter." To my annoyance, she sat on the arm of my chair, much to my discomfort. She smiled at me, leaning closer. "Yoruichi."
"Oh fine!" She stood up, bearing her teeth much like a cat would. "I talked to the elders today. Byakuya... you, ahem, aren't going to remarry. Of course. But, um, a heir is needed. One with high spiritual pressure, so the clan can continue to lead, powerfully. And Rukia is the only remaining..."
She trailed off, seeing my expression.
I was mortified.
Rukia. My younger sister.
Despite popular belief, Rukia is the most important thing in the world to me now.
'I don't want any man... touching her. She is so young and just like her sister, beautiful, no man is worthy.'
A wave of panic swept through me. No. I would not allow Rukia to be touched.
"It has been ordered, Byakuya."
Well. That changed everything.
"High Spirtal pressure, Yoruichi? Well, Rukia's power is enough that she needs a very... intense suiter. A lieutenant, I suppose? Renji will suffice."
Yoruichi sighed heavily. "No, Byakuya. There is only one man who they believe will provide a child strong enough."
"Whom?"
"...Ichigo Kurosaki."
