Tai Chi
She was a student of Zangan, following the way of the fist. She was also the town's best tour guide. And damn, was she pretty.
He was a SOLDIER, first class. He was a 'monster' with a cheerful grin. And he was pretty much welded to her side.
Admittedly, it wasn't his fault. It was Sephiroth, of course. He'd bookmarked Zack as her escort the second the photograph had been taken, and Tifa had moved closer to him to create a marked and pointed contrast between Spehiroth's prideful aloofness and the rest of the world.
Of course, she wanted to fight, to show off her martial prowess. It's natural that you want to use a skill you've got, just like equipping new materia to observe the effect. But he couldn't let her- firstly because Cloud was literally fifteen seconds behind him and watching like a hawk, and secondly because all her 'martial prowess' counted for squat up here. He was SOLDIER. He knew what battle was.
"So, you're in SOLDIER, right? A friend of mine went to join when I was a kid. Ever hear of Cloud Strife?" she asked.
The soldier tailing them mis-stepped briefly.
"Uh...Sure. I mean, I went through the training with the guy." Zack lied easily, noting the playful shake of Cloud's machinegun. "But we, uh, got assigned to different squads. I hear he's doing fine."
"Oh, that's great! Next time you see him, tell him I said hi, will you?" Tifa smiled, grabbing his arm with fingers used to being fists.
He nodded. With a happy clap, she released her vicegrip. But he couldn't help but feel his skin prickle warmly where her fingertips had been.
