[Part of him is surprised they even showed up at all. He had to wait two weeks for Akamaru, though summoning had never been an option.

Kiba registers the barking with an unsurprised stare—though the barking may or may not be much of a hinderance to the understanding of the ensuing conversation—however, some of the resigned disappointment still registers in the stiff, emerging frown, even if the results are better than Kiba expected. The real test is whether or not they still bark in face-to-face interactions. Kakashi seems to understand them fine, but Luceti treats animals by its own set of random rules. Meanwhile, Akamaru's muzzle snakes into closer view of the camera. Someone, at least, feels excited.]

Probably power limitations. ...And if you're actually managing to summon them from Konoha. [Versus gods-know-where. He's not going to even hazard a guess.] Both. They're also talking dog, by the way. Might just be how it looks and sounds while we're communicating with these, but you're gonna want to get that confirmed by someone else face-to-face just in case.
