[He sure is just Some Guy™ to Ochako, but she knows better than to just assume that. Most people that wash up here have some kind of potential of some sort - a talent, or a skill, something that makes them special in their own way. Even if it's just being good at a sport or something. And those gun skills...yeah. He's not telling the whole truth, but she doesn't feel like he's a bad guy, just protecting himself, probably. That's to be expected in a strange, new world. Ochako was the same, more or less - you never know who you can trust.]

Ehehe, well, I've been here a while, go out a lot for shopping and stuff, and just haven't seen anyone like you before. And it's about that time where new people show up, too. [She bows, or...erm. A-As best she can, with that big stuffy still in her hands.] But it's very nice to meet you. Eriks-san, I'm Uraraka Ochako.

Did you get told about this place already? If I remember, there's usually locals to welcome newcomers, but not all the time.
