[WELL at some point this particular wakizashi will wander on over. Horikawa definitely hesitates for a few moments before deciding to address the man outside, but all in all, when he does his tone is good-natured with helpful intent. So he trots on over to look up at him and do just that.]

Are you looking for somebody? [There's a short pause, but apparently he had something specific in mind.] Er, well, I know that we run the dojo, but I don't remember anybody outside of Mikazuki-san getting hurt, really. Do you need help finding the right apartment?

[He's jumping conclusions about that basket of fruit and get-well gifts, but at least his concern seems genuine? Let him help.]
