Finally, in this repetitive dogfight, Archer's Vimana was in a position pursuing Berserker's F15. If he reduced the distance between them a bit more, he would be in a perfect position to attack. Aware of this, Berserker pulled further from his pursuer, pushing his craft to full throttle, then using the acceleration from his descent to perform what is known as a full vertical descent.

“Stop your useless struggle...”

Archer accelerated the Vimana while chuckling, and was once again in Berserker's tail effortlessly. In the blink of an eye, the two shot through the clouds, falling back down to the flickering lights of Fuyuki.
