Training
It's only in the aftermath of Aizen's and Gin's and his own captain's betrayal, when the adrenaline of it all has worn away, that Hisagi finds his world slowly unraveling. Suddenly, he has too much time - to think, to brood, to wonder just what exactly the creeds he'd been following means. Meant. Paperwork is too tedious, but he ends up doing it anyway and letting his mind wander.
Until there's a knock at his door, and Hisagi opens it to find Yumichika standing there as though it were the fifth seat's own home. (And it's hard to resist checking that yes, he does own the potted plant sitting by his foot.) He isn't particularly sure why the fifth seat is there, but it's a welcome distraction nonetheless, and before he knows it Yumichika has taken over his usual chair.
Yumichika gives him a measuring glance before nodding, and Hisagi wonders just what kind of test he's passed. "You won't tell," and Yumichika looks inordinately satisfied. "Then," Yumichika stands up, unsheathes Fujikujaku, "shall we spar?"
It takes Hisagi a moment to process the other shinigami's request, and when he does, the only answer he can give is, "huh?"
Yumichika plows on. "Well? Hurry up."
"No."
Yumichika frowns, like a spoiled child denied his favorite toy, before pleading, "Just once?" And somehow, even though Shuuhei says "no", he finds himself standing opposite of the fifth seat anyway with his zanpakutou at the ready.
He wins (of course, and by his standards), and Yumichika merely smiles and starts changing clothes in front of him. (And later, he will flush red when he remembers, but at the moment he is merely thankful the other shinigami didn't do anything.) Perhaps Yumichika is just building his trust, for whatever reason he can't fathom, except they end up sparring near daily to the point where people begin to notice he's become very busy indeed. "Who's the girl?" Iba grins at him and the rest of the gang all start snickering when he says it's just training.
"So that's what you're calling it now, huh?"
A pause from himself, before he grumbles in annoyance. The subject is dropped, to his relief, only to re-ignite with much fervor when he accidentally wakes up in the same bed as Yumichika a week later.
He would have thought he'd learned by now that drinking in groups was never a particularly good idea. He still can't remember how he ended up in Yumichika's bed either, but more worrying to him is that it doesn't really bother him at all.
Well, until they're seen leaving together, anyway.
"That's your girl?"
"I'm a guy, Ikkaku."
"Pansy."
"Screw you."
"I masturbate frequently, thanks for your concern." (Hisagi admits to himself that he's rather lost now, and isn't particularly sorry for it.)
He tries to salvage his own pride, speaks up, "It was just training."
"For stamina, I'll bet," with a wink and a grin. "Gotcha."
Hisagi chokes at the words and decides to shut his mouth before he does any more damage.
