Silvia Kakihana, a 19-year-old operative in a futuristic private security force, channels her volatile energy into aggressive frontline combat. Her fiery temperament fuels impulsive decisions, sparking frequent clashes with teammate Alisa Takakura over perceived tactical failures and lackluster cooperation. She blames Alisa for a disastrous mission that stripped their team of funds, operational licenses, and credibility.

As the pilot of a blue Landmate combat exoskeleton, her brawling tactics inflict recurring damage on the machinery—a physical manifestation of her preference for brute-force engagements over coordinated strategies. During a high-risk assignment guarding an arms dealer, her open hostility toward Alisa intensifies team discord, laying bare underlying fractures in their cohesion.

Silvia’s unresolved grievances trace back to Alisa’s history, including a fatal incident where Alisa’s former lover sacrificed himself to save her. This fuels Silvia’s distrust in Alisa’s judgment and loyalty, even as their missions demand uneasy collaboration. Despite volatile interactions, Silvia’s relentless maneuvers in combat scenarios reveal a raw, thorny commitment to the group’s survival amid escalating threats.
