Yamamoto watches her while she apologizes and waves it off, not bothered in the slightest that she'd run into him. He's a pretty big guy for his age, so he's just glad that that collision hadn't knocked her down. Then again, he hadn't been moving, so... it's all good!

"Haha! Yeah! I guess so." And he brushes the sleeve of his shirt off right on the forearm just for show because hey, the most damage she'd done is wrinkle it and maybe startle him a little. The swordsman may be able to play cool, but he's underage and still trying to digest the fact that he is very much lost and confused in a place like this. It's a lot of pressure, really and somehow... it's not so heavy when he can see someone else smiling at him. His own softens into something less dorky and he takes a step back to allow her more space. Really, it will make him more comfortable too, considering he feels bad about the fact that he's staring on top of acting goofy around a complete stranger. Who is he trying to impress? Come on.

"It could have been worse then that, right? Hehe!" She could be a man, or someone threatening, or... someone trying to have sex with him? Yamamoto isn't sure what to expect, and he tucks some of the beads around his neck down out of sight to leave only the black one exposed.
