Explanation - Ado Edem

The Ether Liner who manifests the Knight Arm, Slash Emperor.
He was an Ether Liner who did not stand out much during the war with the A-rays, but suddenly rose to prominence when the Aristoteles invaded.
He used Slash Emperor to slash through “The Black Aristoteles” (Type:Jupiter) in a single blow.
Later, because the power of his Knight Arm was too great, the A-Rays, Liners, and many Ether Liners united to imprison him in the Witch Swift Umbrella, a disposal area created in the Great Rift.
…As the war with the Aristoteles approached a close, he was seen as humanity’s trump card and thrown into the conflict, and was able to destroy “The Cross” (Type:Saturn), the fortress-like Aristoteles that had been attacked uselessly for a long time. His fate afterwards is unknown.

Explanation 02: Witch Swift Umbrella

A castle built in the Great Rift.
Its name originates from its scaffolding, which looks similar to a large, upside-down, open umbrella.
The original form of the Millennium Castle Brunestud from Tsukihime. A prison resembling a castle, with many walls and layers of gates linked with thousands of chains.
Even standing up from the throne would require enough power to destroy the entire castle.
Additionally, it is said that in order to reach the throne, one must pass through 78 “magic doors” that a normal Ether Liner would be unable to destroy.
