Huh!? Yuuka, you can use ninjutsu!?

I most certainly can not.

But I wanted to see iiiit! Yuuka's ninjutsu!

Hey now, I said I can't use it!

Just this once!

Just this once, okaaaaay!?

Your thigh-sandwiching jutsu is amazing, Yuuka!!!!

They did lots of black magic afterwards. probably a pun on ninjutsu -> youjutsu (black magic), which literally means "bewitching/attracting art"

Oooh...!
