The MSJ-121 Demi Trainer was a training mobile suit manufactured by Burion for use by students at the Asticassia School of Technology. The Demi Trainer’s design was maximized for superb maneuverability and serviceability. It could be modified by anyone with basic technical knowledge, which allowed for a wide range of customizations. The Demi Trainer was equipped with wheel dash units in its heels that allowed for ground dashing maneuvers. It also implemented the Daedalus multi-tool system that used standardized blocks to allow equipment and weapon swapping. The Demi Trainer could also equip a staff antenna for use in duels where the objective was to sever the enemy’s antenna. The suit’s standard armaments included a beam gun (set to low energy output for duels), a saber stick and a shield. Optional armaments included a combat knife, Gatling gun and 4-tube missile launcher.
