This machine is the basis for all B-class HMs and was created with a focus on reducing the cost of A-class HMs. It uses many A-class parts and has the closest performance to the A-class among the B-types. It was also deployed to the Poseidal Army's Royal Guard. It is equipped with a saber and power launcher. The mobile frame is M-size. It was designed by Valved Kawaranga and was then modified by Poseidal to complete the machine. It is available in orange (standard machine), dark blue (Royal Guard Division machine), and blue (Chai Char's machine in episode 15 and Gabret Gabree's machine in episode 27).
