It features character and mecha designs by Shigeto Koyama, 3DCG animation by Sanzigen, and music by Hiroyuki Sawano.

Meanwhile, Freeze Force manages to track down and recapture all of the Burnish population except for Lio, whom his companions send into a nearby volcano.

Enraged by the mistreatment of his people, Lio unleashes his hatred and transforms into a giant flaming dragon that burns down the city with the intent of confronting Kray.

The flames melt the ice, revealing a laboratory run by a holographic projection of Deus Prometh, a scientist whom Kray killed.

He explains that the Burnish can communicate with the Promare, a race of interdimensional flame beings who came to reside in Earth's core after a dimensional rift opened shortly before the Great World Blaze.

The surging magma is a side effect of subjecting the Promare to pain, and Kray's experiments on the Burnish using incomplete, stolen technology are accelerating its growth.

Using a drill Prometh designed, Galo reaches the ship's core in time and defeats Kray using Lio's flame.

Nakashima and Trigger are credited for the original work, with Shigeto Koyama providing the character and mechanical designs, Sanzigen animating the 3DCG sequences and Hiroyuki Sawano composing the music.
