Shin no regashī
True Legacy (真のレガシー Shin no regashī) is a Rumble Magic Spell.
The user Launches punches that literally cracks the air itself and sends devastating shock waves through the air in the direction it is facing. These shock waves are able to pass through and damage almost any substance, literally tearing it apart. If the shock waves are directed into the ground, the result is a devastating earthquake capable of generating huge tsunamis.
