This is the mobile weapon piloted by Blood Skywind. It is one of two developed for the "Bukihaken-ryu" fighting style, a giant humanoid weapon. It has no fixed armaments, and attacks are limited to the upper body, with melee combat carried out using its "fists" and "elbows."

It is powered by electricity and the pilot's "bio-energy." However, electricity alone is only enough to activate it; to fight, the "bio-energy" must be converted into power. Special training is required to derive this "bio-energy."
