Another in the "firsts" headcanon 'series'. These will be in no particular order, I'm just writing them as they come to me. :)

This particular one-shot is based off of the headcanon that the first time Kai & Miah kiss is during a fight.

Kiss

"You're such an asshole!" Miah exclaimed, throwing some kind of inanimate object at Kai's retreating back. The way he dodged it without even bothering to look was a testament to how often these kinds of arguments occurred between them.

"I figured you'd be used to it by now," he replied over his shoulder. Miah gave a frustrated sound, tugging at her hair in agitation.

"Don't make me kick your ass, Hiwatari." she growled, hands balling into fists in preparation to follow through with her threat. The fact that Kai paused at the door was yet another testament to how often brawls followed these kinds of arguments. His crimson eyes narrowed and he took a step back into the training room of the Granger dojo, shutting the door quietly behind him.

"You threatening me, Kon?"

"Damn straight." Her golden eyes burned with the need to fight, both verbally and physically. If there was one thing she knew she could count on Kai for, it was a good round of combat. It was the only thing about him that she even remotely enjoyed.

He stalked towards her, movements careful and measured; he always knew the difference between when she was picking a fight because he'd offended her and when she was seeking self-punishment. It would show in the tone of her voice; at this particular moment, she sought the latter of the two.

Self-punishment wasn't surprising to him; the Abbey left a mark on all its victims that each individual had to deal with in their own way. He was no stranger to self-flagellation, and had often found ways of doing exactly what Miah was doing now. It was something, at least, that she was doing so through him rather than getting herself killed out on the streets, like he'd often attempted.

Still, Kai mused as he came to stand a few feet away from the female, he couldn't just beat her up every time she felt like shit. Ray had already warned him that if the two kept up their unorthodox "sparring", he was going to be one very unhappy older brother. It was just as well that Ray didn't know about Miah's gluttony for discipline.

"We gonna go, or what?" Miah demanded, balancing on the balls of her feet in a ready stance. Kai deliberately tucked his hands into his pockets and regarded her as though bored.

"It'd be a waste of my time," he replied, meeting her eyes directly in a challenge. "You couldn't land a punch if I swung your fist for you." He was bluffing, of course; he knew too well the strength she packed behind her right hook.

Still, the jibe gained the desired reaction as Miah launched into a stream of curses.

"You son of a b—!"

"Shut up." Kai growled, reaching out to grasp her chin, simultaneously pulling her towards him as he leaned down to meet her halfway. She had time to grab his wrist with both hands, intent to get him to release her, before freezing in shock when he captured her mouth beneath his.

The kiss was harsh, filled with pent-up anger and an unfamiliar loss of control. The fingers gripping her chin were tight against her jaw, holding her in place as he ravaged her mouth, thrusting his tongue against hers in a whole new kind of battle she was at a loss on how to win. She felt his growl reverberate against her lips when she didn't respond and the sudden pain spreading over her bottom lip told her Kai wasn't up for playing games. Before she had a chance to return the favor, however, he pulled away and released her.

"It seems I've finally found a way to silence that smartass mouth of yours." He smirked, tucking his hands back into his pockets. Miah stared at him, too stunned to reply.

"Just remember," the Phoenix wielder warned as he turned to leave. "Next time you want to pick a fight with me, it might not end the way you imagined. See you around, Kon." And with that, he left her alone in the training room, staring wide-eyed with curious fingers pressed to her lips.

Thanks for reading! Hope you enjoyed! R&R is always appreciated! :D
