Toshinori places a great deal of power into his fist and then throws a right punch with enough force that the wind pressure sends anything made of liquid flying away. It is first used to save Izuku Midoriya from the Sludge Villain.
Toshinori also used this move in his weakened form to punish Izuku for saving Katsuki Bakugo; in this instance, the move had the same effect as a normal straight-forward punch and simply knocked Izuku to the ground.
Izuku would later use this move against Tomura Shigaraki to fight him during the Paranormal Liberation War.
