Meis serves as Lio Fotia’s trusted strategist within the radical Mad Burnish faction, balancing Gueira’s fiery impulsiveness with his own methodical composure. Their shared zeal for combat unites them, though Meis’s calculated decisions—such as orchestrating tactical surrenders to infiltrate Freeze Force prisons—solidify his role as the group’s architect of subterfuge.

Tall and lean, Meis’s appearance is defined by dark blue-purple hair obscuring one eye and a tattoo etched on his left shoulder reading “風刃” (Wind Blade). He sports a pink tank top, black pants accented by a wallet chain, and black shoes with white-tipped toes. When ignited as a Burnish, his armor morphs into an insectoid silhouette crowned by a single azure horn, complemented by bladed claws.

Before pledging loyalty to Lio, Meis and Gueira jointly commanded Mad Burnish, spearheading arson campaigns and recruiting Burnish like Thyma. During a raid on Foresight Pharmaceutical, they encounter Thyma mid-crisis, soothing her fears of uncontrolled pyrokinetic power. Lio’s intervention during a Freeze Force ambush—advocating peaceful resistance over violence—prompts Meis and Gueira to cede leadership, inspired by Lio’s vision of refuge.

In a daring gambit, Meis allows his capture alongside Lio and Gueira to breach a Freeze Force stronghold, later engineering an escape and securing transports for freed Burnish. Facing annihilation near an active volcano, he and Gueira stall advancing enemies through a self-sacrificial stand, enabling Lio’s retreat. Though imprisoned as a power source for the Parnassus initiative, Meis survives to combat Earth’s apocalyptic threat.

His unwavering fidelity to Lio manifests in life-risking gambits and absolute trust, while his bond with Gueira—forged through matching tattoos and harmonized armor hues—anchors a partnership spanning years. Together, they execute precision maneuvers, from synchronized motorcycle assaults to shielding Lio, embodying their dual role as lieutenants and guardians.
