Yapan Exodus
Gainer is the headstrong main protagonist of the series. He lived his days as a high school truant and online gaming champion before meeting Gain Bijou, an Exodus specialist under the captivity of the Siberian Railway forces. Gainer initially opposes the Yapan Exodus, but through a series of coincidences and his connections with Gain and Sara, he suddenly finds himself soldiering for their cause. He pilots the long-haired Overman dubbed "King Gainer" after his online gaming handle. Despite being considered a "general purpose" Overman, King Gainer is frequently noted to be far faster and more powerful than an Overman of its class should be. This is eventually revealed to be because King Gainer is actually part of the same class of Overman as the legendary Overdevil, which makes it capable of using the Overfreeze and Overheat Overskills.
Sara Kodama is a diligent high school student and member of the Gauli Squad, a rebel soldier faction which supports the Yapan Exodus. Her work ethic is matched only by her heart, which she devotes mainly to Gainer. Her plan upon completion of the Yapan Exodus is to cultivate a farm. She primarily pilots a Panther-type Silhouette Machine as a scout.
A self-proclaimed 'Exodus specialist', Gain is an expert sniper and important member of the Yapan Exodus. His nickname, 'Black Southern Cross', was earned by his reputation for leaving bullet wounds in the shape of a cross within his fallen enemies. His affable demeanor outside the battlefield is pierced upon discussion of his mysterious past. He pilots the Silhouette Machine named Gottiko, which is mounted with a large railgun and has an Overman's left arm, later revealed to be one of the left arms of the legendary Early Overman Brunhilde. He later pilots the pseudo-Overman known as Emperanza, which is built from both Overman and Silhouette Machine parts, including the salvaged left arm of Brunhilde. Brunhilde's arm gives either machine limited control over gravity, typically used as a barrier against attacks.
Princess Ana is the daughter of Duke Medaiyu. Her lively nature and insatiable curiosity lead her to join the Yapan Exodus under the guise of a hostage. She owns three intelligent pet squirrels that heed her every command.
Ana's kind, brave, and loyal retainer. She has trouble keeping up with the princess at times and wishes to protect her at all costs.
A commander of the Siberian Railway forces who mistakenly arrests Gainer just before the Yapan Exodus commences because of a case of mistaken identity. When the Yapan Exodus sets off, Adette infiltrates the traveling city units in order to capture Princess Ana. Gain quickly thwarts her attempt, and with nowhere else to go, she begrudgingly starts a new life on the Exodus as a high school teacher for Gainer and Sara's class. She also moves in with Gainer to his chagrin. She is a tough and shrewd woman, but childlike in her temper and affection toward men. She eventually begins commanding a troop of Exodus soldiers fanatically devoted to her, piloting a Dorbeck-type Silhouette Machine painted in her signature red.
A fellow Gauli Squad member and classmate of Gainer and Sara. He has feelings for Sara, but never seems to show them outside random acts of jealously toward Gainer. Despite this, he remains good friends with Gainer and Sara and a helpful ally on the battlefield. He typically commands the Bachclone, the lead Silhouette Mammoth vehicle towing the city blocks, which is also typically where King Gainer is stored.
A quasi-religious figure idolized by Exodus supporters, who is a key feature at festivals as she sings and dances. Despite her apparent status as an important figurehead, she is often treated more like a pop idol and has a ditzy and easily distracted nature.
Meeya's handler and manager.
Hughes is the commander of the Gauli Squad, trained in the way of the ninja. He'll stop at nothing to support the Yapan Exodus.
Cona is the temperamental young mechanic who repairs the Silhouette machines and King Gainer. Early on, she competes with Lioubov for Gain's affection, but quickly moves on to capture the attention of Gain's former comrade.

Siberian Railroad Authority
Initially Gainer's online gaming buddy with the handle "Queen," Cynthia is actually an elite Siberian Railway soldier, raised and favored by Kizz Munt. She is almost always eating candy and treats everything, including piloting and dating, as a game to conquer because of her sheltered upbringing. Her trademark whimsy and inability to take things seriously comes with major consequences, as she ends up hurting a Gainer later in the series during a friendly piloting competition between Overmen. Cynthia's natural piloting ability is said to have come from her mother, whose name is never mentioned; her only living relative appears to be Martina Lane. The shape-shifting Dominator is her Overman of choice.
A Siberian Railway squad commander who originally pilots the time-stopping Overman Rushrod and later the stealthy Overman Blackmail. He is the first major opposition the Yapan Exodus faces. After being captured by the Yapan Exodus and escaping, he meets a young fortune-telling girl in the city blocks and they decide to Exodus together to her homeland in the south. He is only 32 years old despite looking much older.
The operations director of the Siberian Railway, a flamboyant man obsessed with maintaining the perfect "diagram," meeting any deviations to his meticulous scheduling with unchecked rage. He primarily pilots Netter-type Overmen with Overskills that affect the minds of opponents and avoids direct combat whenever possible. He also once pilots the Antlion, a quadrupedal drilling Overman.
A Siberian Railway officer who is initially Adette's direct subordinate. She is noted to become fanatically devoted to anyone in power, clinging to whoever is the highest authority at the time.
A Siberian Railway officer obsessed with gaining ranks and status. He is partnered with Enge and is denoted by his ugly face and bad posture. He is usually controlling a Silhouette Machine, but is given an Under-Golame Overman when briefly under Asuham Boone's command and once pilots the Overman Mexbrute, which can create illusions.
London IMA
A high-ranking member of the Saint Regan police force who is dispatched to help stop the Yapan Exodus. His only real objective is to capture Gain and force him to confront his sister, Karin, who has conceived and raised a child from a one-night stand with Gain. His obsession with Gain ultimately degrades into homicidal madness, culminating in him intentionally awakening the Overdevil to destroy the world. His plans are derailed after the Overdevil is defeated and Karin suddenly arrives to drag him home. He usually pilots a Golame-type Overman, which is a mass-produced London IMA model for high-ranking pilots. He also once pilots the Overman Jinba, with the ability to "steal" anything within a certain range, and steals the Dominator from Cynthia later on.
Asuham's direct subordinate, who typically pilots a Golame-type Overman.
