Zettai Reido; Absolute Zero HQ

Description
A giant mobile fortress that serves as the headquarters for the Absolute Zero Gang (Zettai Reido-Dan). It implants itself wherever they wish to set up camp and do their business as rebels, under the direct order of the gang leader, Triere. Little is known about it, but it is completely reinforced with her magical power to ensure that it remains protected from outside threats, even when she is away.

History
Once a tower that belonged to Medusa in the outskirts of the Dusk, after her death, the old tower was taken over by the Absolute Zero Gang and made as their secret headquarters. It was fixed up by Koudo under the direct instruction of Triere, the leader of the Absolute Zero Gang, and transformed from a stationary tower into a giant mobile fortress.
