Soundwave Vibration-Enhanced Flight Feather Blade

Soundwave Vibration-Enhanced Flight Feather Blade is an Ultimate Move performed by Keigo Takami using the Fierce Wings Quirk.

Description
Taking advantage of Kyoka Jiro's Legato, Keigo flies around and hits his opponent with his katana with enough power to break even the toughest of materials.

Keigo first uses this move against All For One during the Second War. After repeatedly striking in the same place against the villain's protective helmet, he uses this move to crack it open.
