Eh? Mutsunokami??

[And he's being referred to so formally!? This is weird... what is going on here... That kind of feeling probably shows on Horikawa's face as he takes note of the name, though he recomposes himself quickly enough to try and make up for that.]

Ah, sorry then! I don't think he's around right now. [Cursory glance over the shoulder. Yep, can't see him, he's gone!] Would you like to come in anyway? I'm sure that he'll come back eventually.
