Undress, Escape
The light of the moon is shining on a guard who’s been on duty all night. In fact, the moon light is making him so warm, he’s trying to undress and escape! Somebody stop him!
Picture the guard being so warm from the moonlight that he’s trying to simultaneously undress and escape. You can’t just let him leave his post!
だつ
ぬ
None
You’re unable to stop the guard from undressing and making his escape, so you decide to start throwing some darts (だつ) at him. Perhaps that’ll make him stop.
Imagine yourself desperately throwing darts at the undressing, escaping guard, trying to make him stop. Or perhaps trying to pin his clothes to his body using the darts. Anything to stop this madness!
