"Get your eyes checked." Lying comes easily to the demon, as naturally as breathing does for humans. And his human form is going to be feeling it once he gets away from here. He needs to get away from here; he could make the fight louder and messier, but at what cost? He'd attract all the worst sorts of attention to himself if he kept this up for much longer...

...and there is the matter of that wound, that too. The bow that had gotten stuck in the ground vanishes, and Hajime uses her getting stuck as an opening to try to get away and out of there, as much as it pisses him off.
