Kuroo's heard some murmurings about an issue at the inn, and it seems like it's worth looking into - especially since it sounds like it pays. They all need to be looking for ways to make money, and at the moment there aren't a lot of options for someone like him. Best to investigate all possibilities that don't blatantly sound outside his capabilities, then.

It's as he's making his way to the inn, his Rabite (which he's named Lev) lolloping along behind him, that he spots Iwaizumi. He changes course on a whim. "Hey, if it isn't Iwa-chan~."

Kuroo's like a very low-key Oikawa when it comes to irritating people. Of course he'd mimic him for a laugh. (Unlike Oikawa, though, he'll probably knock it off when requested.)
