Twist
"Take your fingers. Now, put them on your foe's heart and twist." These are the words of your martial arts master as he teaches you his final, ultimate technique: the "finger-heart twister."
ねん
ひね, ねじ
None
The last challenger to appear is… your own master, who taught you the twist technique. Turns out he's a nendoroid (ねん), so he doesn't even have a heart for you to twist. Welp, you're screwed.
