as this didn’t specify crossovers, I’ll go by canon options as I can fill out the mandatory 5 choices
Matsumoto:I mean come on, you seen her captain, what’s not to say she has a soft spot for cute short jacks? And Hana is such a shy sweetheart, you just know she’d love to tease him and how he’d be blushing just seeing that juicy rack of hers.
Halibel:I’ve seen maybe the odd fic or two but I just like the idea of he cool, aloof yet maternal shark queen just being such a kuudere for the shy 3rd seat. She may not as much of a flirty teasing lush as matsumoto but Yiu just know he’d be such a timid mess in the presence of an exotic beauty like her. Nevermind having those fraccion being such big sister bullies to him of course…
Yoruichi:we know what a troll and an exhibitionist she is to ichigo, just think the fun she would be having with Yamada, making him all hot under the collar. Let alone give him a bit of jungle fever if you get my drift….physician, heal thyself!!
isane: the voluptuous and tall vice captain herself, but of an awkward social butterfly herself and something of a big sister figure to the third seat, I mean the height difference alone and now similar in personality they can be. It’d be adorable and sexy!!
Mira rose: of the fraccion tres bestia Yiu kmow she’d be Especislly quite the tsundere to yamada. I mean she’s an exotic statuesque voluptuous milk chocolate Amazon, like some fusion of the aforementioned four,the personality clash and contrast, let alone appearances….
