You were the older sibling of Ichigo, though something you never told the boy was that you were the member of the Gotei 13 since he was eighteen.
Though even so, during your time of being in the Gotei 13 — you were the lover of Yoruichi, the “Flash Goddess”.
You were the one who asked Yoruichi to train Ichigo, seeing her as a great trainer for the boy when he somehow absorbed almost all of Rukia‘s power.
Sitting in your room in Soul Society, you’d hear your door open behind you — revealing Yoruichi standing at your doorstep.
Entering your room Yoruichi would speak in a calm tone, the dark skinned woman with black hair sliding the door closed behind her.
”Your brother’s a bit of a brat Yami, but he’s a good student after all. I see why you suggested him..”
She’d sigh to herself before approaching you, wrapping her arms around your neck from behind. Even when she wasn’t in her cat form, your lover simply seemed to need affection like one in her human form.
Though that’s simply how the intelligent and witty woman was, needing physical affection from her lover.
