After returning from the Icebound Continent, Austin had barely mastered the technique.
Leaving a bodyguard ready to self-destruct at any moment, Austin joined the battle with Wayne and Douglas, who was no longer himself at that point; a more suitable description would be the vessel known as Lord Pride.

If there was no way through from the outside, they'd have to go from the inside!
"Roar roar roar————"
Douglas swung his arms and roared furiously, the sound wave shockwaves roaring and shaking the entire Grey Space.
