The user first turns around as a thin stream of water surrounds them. The stream then gathers up and the user swishes their arm as a jet of water goes to the opponent. The opponent is stopped since the user is in their way. The user then motions their arm near the opponent's face and swishes their arm, turning the jet of water into a diagonal slash and causes the opponent to fall down.
- This hissatsu is most likely based off the usage of a Jackknife.
