Sea God's Descent

Union Magic: Sea God's Descent (合体魔法『海神の下ろし』) is a song- and butoh-based Union Magic spell.

Description
While underwater, the dancer swims overhead of the target, and the singer enhances the dancer's swords and movements. The dancer is then propelled down with tremendous force, knocking back and injuring the target. The resulting shock wave can be used to handle multiple targets.
