Haisangen is a grapple-based martial arts technique utilized by I-Pin's alternate future self.
Description[]
I-Pin first positions herself on top of a target's shoulders, preferably while they're standing, before proceeding to wrap her arms and legs tightly around the opponent's upper body, locking their head as well as both of their arms in place. Once she finally has their limbs properly restrained, I-Pin ruthlessly curls her body, breaking the target's arms whilst snapping their neck as well.
