[ normally young, nineteen-something men should know a lot about cities. but when he was a young boy, yamato no kami yasusada never got taken to the city (i mean, they tried, they really tried, but he kind of fell off a wagon and that was the end of that riveting saga). therefore his relative inexperience, coupled with the fact that he's wearing clothing that could pass for something out of a period drama should probably clue oikawa on how little he probably knows about what's happening around them.

still, he tilts his head politely at the person who's plopped down next to him. young, but human, so as a sword forged to protect these very people, he should show due respect, even though his blue eyes are calculating-- sudden movements draws and keep his attention. he's prudent by nature, if not wary. however, his otherwise pleasant expression falls a little as he tries to fully understand the context behind the other young man's words. ]

Ah... Tokyo. If I recall, that's the new name they chose for Edo. [ after all, okita died just on the cusp of change. he'd remember this much. yamato blinks, surprised. ] I hadn't known that Tokyo now has metal snake carriages like this one. Are they truly so commonplace?

[ he's from ye olde japan ok, trains were not really Things back in ye olde japan. cut this grandpa some slack pls. ]
