Rogues To protect humanity and turn the tide of war against the Draktors, the united world government built armored bipedal machines called Rogues, which are designed to be mass-produced and are used as cannon fodder for their more advanced successors. Some time later, development on a series of next-generation Rogues aboard the Shelter Ixia was finished and later dubbed Megaton-Class Rogues, which are more powerful and durable due to being made from Megatonium, a type of metal said to be stronger than previously discovered metal. ;Musashi :The titular mecha of the series, who is named after
Miyamoto Musashi and primarily piloted by Yamato, with Teru and Ryugo also occasionally operating it before they receive the Sparkman and the Gaudia. Musashi is the "jack-of-all-traits" among Megaton-Class Rogues and wields twin swords, also possessing the ability to shoot a beam from the Diffusion Cannon in its torso. Unlike most Rogues, the Musashi has three components: the Upper Torso, the Arms and the Lower Torso, which must be assembled together on higher altitudes through the
Sky Build (スカイビルド,
Sukaibirudo) formation. ;Arthur :A mecha named after
King Arthur and primarily piloted by Reiji. It wields a sword and excels at close-quarters combat, and its centaur-like lower body gives it greater mobility and agility than other Megaton-Class Rogues. ;Maximus :A mecha named after the
Pontifex maximus and primarily piloted by Jun, with Momoka as co-pilot. It excels at ranged combat, as it can use the missile pods in its body to fire homing missiles. ;Sparkman :A mecha inspired by
Thomas Edison and primarily piloted by Teru. It constantly generates electricity, which it can use to augment the power of its weapon or attacks. ;Gaudia :A mecha inspired by
the Spartan army and primarily piloted by Ryugo. It is the physically strongest of the Megaton-Class Rogues, with its large body giving it both high offense and defense. ;Musashi-O :A mecha based on a copy of the Musashi's blueprints, built in Solon by Victor. It was originally piloted by Masamune before he leaves to infiltrate Ixia, after which it is primarily piloted by Victor. It is equipped with a rear deifter vernier, giving it superior maneuverability compared to the Musashi. ;Fire Loader :A mecha inspired by retro American cars with a fire paint job. Primarily piloted by Masamune. It is developed by Takumi based on the combat data from the Draktor mecha Balrog, and is customized for higher movement flexibility, attack variations, and heat resistance to accommodate Masamune's piloting style. ;Brahms Soldier :A mecha with a medieval soldier motif. Equipped with extra propulsion engines and designed for increased cold resistance. Primarily piloted by Shizuka. ;Mad Bison :A mecha with an post-apocalyptic wasteland vehicle motif. Designed for high offensive output in exchange for minimal defenses. In the game, one is assembled with parts salvaged by the townspeople of Solon. This particular one is nicknamed "Tetsuo-bot" and is primarily piloted by Tetsuo. ;Dark Knight :A Draktor mecha piloted by Grieffas and several other Draktor officers. Equipped with a force field-generating mechanism to greatly reduce incoming damage. In the game, parts of an abandoned Dark Knight are salvaged by Victor and used to assemble a Megaton-Class Rogue that is primarily piloted by Arshem.
Pilots ; : :A hot-blooded boy with a short temper but a strong sense of justice. His family was killed during the Draktor invasion, which he has recently been experiencing flashbacks of, and he becomes Musashi's pilot to take revenge on the Draktors. However, after meeting Arshem, he begins to reconsider his attitude towards the Draktors. ; : :A delinquent who leads a gang that frequently gets into street fights, he is actually kind and compassionate to others, especially children and the elderly. Despite being a Seikoku Academy student, he forgoes the standard uniform in favor of an outfit reminiscent of
Showa era biker gang members. Lives in a nursery called Sunflower Garden, of which his mother Minae is the director. Recruited at the same time as Yamato, he initially serves as a co-pilot of Musashi, and is later assigned his personal Rogue, the Gaudia. :The queen of the Draktors and Arshem's mother. ; : :Crouzade Laia's daughter and princess of the Draktor, who seeks coexistence between her people and humanity. She briefly pilots the Musashi-O during her time in Solon, and in the game, she is an optional Megaton-Class Rogue pilot unlockable via a
side quest. ; : :A loyal knight who has served Arshem since her childhood. ; : :Supreme commander of the Draktors. He pilots a Dark Knight (Vohda) Draktor mecha, which can transform into the Dark Knight Emperor (Zerk Vohda) using Mass Expander-like technology. ==Media==
