A technique that physically restrains an opponent, as if the opponent had been tied in invisible steel ropes. It debilitates the victim for a short period of time, which allows the user to either strike again, or take the target into custody. This is a D-rank ninjutsu where the intensity will vary greatly according to the user's level of skill. The technique can also be cast on every target at once, depending on the user's skill, and won't fail a shinobi during their missions.
Fūka can execute this technique by simply looking into her victim's eyes, showing how much precision in chakra control she must have and giving her the metaphorical connection to Medusa.
