This Aura Battle Ship was developed at Ouroporos Castle in the Kingdom of Na. Its captain is Kawasse Gu, and it reigns as the flagship of the Kingdom of Na.

It appears to use not only technology from the Kingdom of Na, but also shot weapon technology leaked from the Kingdom of A.

Compared to other Aura Battle Ships, it features a vertical structure that takes three-dimensional combat into consideration, and its appearance is more like an "elegant flying castle" than a battleship or flying fortress. The hull is equipped with a large number of weapons, allowing it to attack in all directions.

However, aside from its three-dimensional combat ability, its performance is lower than other Aura Battle Ships. On top of that, the bridge's shape makes it very noticeable, and it is destroyed many times in the original work.
