St. Louis Smash Air Force

St. Louis Smash Air Force (セントルイス スマッシュエアフォース) is a Super Move performed by Izuku Midoriya using the One For All Quirk.

Description
Izuku draws out 45 percent of his power for a short time. He then arches his leg back and performs a strong vertical roundhouse kick, firing a large blast of compressed air.

Izuku first used this technique to intercept a massive wave of crumbling debris created by Tomura Shigaraki's Decay Quirk.
