Original armslave from Full Metal Panic! Obsidian, piloted by Raizo Muramasa. After the attack in Merida Island Muramasa finally decided to start using a lambda driver mounted as. For that purpouse he obtained two prototypes of the belial for experimenting powerful but unstable lambda drivers, then he customized one with his Jet Armor and a pair of horns. Using always a katana as his main weapon. The LD was really unstable and required so much attention driving him to the limits of sanity. The other prototype was stole from Glen Kuwabara, but Raizo was happy to able to experience a last legendary showdown against a worthy opponent.
