It isn't quite a laugh, to be sure, but a snort breaks free from Ichimatsu's throat before he can stop it. It's probably falling on the side of rude, the way he scans Sans up and down like he's studying a door mouse with overgrown fangs. Is this weirdo just insulting himself, or is that legitimately what he's classifying himself as? With a grin like that, Ichimatsu can't tell... for a guy without any skin or muscles, he has a real smug look about him. It's actually sort of irritating.

Not enough for Ichimatsu to hate the guy yet, though. He seems pretty unthreatening.

"Not buying it," he says bluntly. "My brother is what you'd call a monster. A dry one. I dunno about you."
