He discovered the existence of the Underground Empire Tube, a once peaceful kingdom that has turned into a malignant force under the mysterious Zeba, who desires to conquer the surface.

Each becomes specialized in a style of martial arts, and Sugata teaches them the ways of the mystical Aura Power (オーラパワー, Ōra Pawa).

Its primary weapon is the Photo Electron Riser (光電子ライザー, Kōdenshi Raizā) sword, and it destroys monsters with its finisher, the Final Aura Burst (ファイナルオーラバースト, Fainaru Ōra Bāsuto).

Its other weapons are the Five Shield (ファイブシールド, Faibu Shīrudo), Gyro Cutter (ジャイロカッター, Jairo Kattā), and Great Gun (グレートガン, Gurēto Gan).

The five components of it are: Land Galaxy (ランドギャラクシー, Rando Gyarakushī): A large tractor trailer for the Maskmen, piloted by the entire group.

The Land Galaxy was built as part of a competition to determine the mecha to be used by the Maskmen but was considered too unstable to control when it seemingly killed its creator.

After managing to escape Hell's Wind by mastering the Crescent Screw, Kiros attacks the Maskmen, requesting Ial in exchange for aiding Tube.
