That is some crazy upper body strength and balance she's exhibiting.
I'd like to imagine Nagatoro trained exclusively for the improbable event that some ski bunny floozy tried to hit on Paisen.
That's a line I'd expect from Shikimori, not Nagatoro. She keeps that up and she won't really have any room for her regular antics. Don't think you can really take a tsun act seriously after she comes onto him with some chad moves. What's next? An earnest kabedon?
