[He's so grateful that there's no impact on his head or other body parts for this violation of privacy. Since it's not like he wants to see her unmentionables. Though perhaps it'd be more believable if he would quit staring, huh...]

This place, man... Something is seriously fucked up with it! [A chirruping noise is what eventually gets him to tear his eyes away from Hiyori's lower half as he whirls around, following the direction his ears swivel in.

They're not alone anymore - a pair of yellow eyes peers out at them from the edge of the darkness, wide and unblinking. He slowly edges towards her, trying to nudge her with an elbow.]

...psst. Hey, Hiyori! Look over there.
