Shin Yamana, a disciplined combat specialist in Jenock's Third Platoon at Kamui Daimon Comprehensive Academy, piloted the LBX DC Aerial during War Time missions. His operational philosophy centered on unwavering obedience to orders, prioritizing hierarchical duty over personal deliberation. During Operation Seize Tandem Harbor, Shin’s DC Aerial sustained catastrophic damage from Ezeldarm’s assault while shielding comrade Rikuya Tougou. Ignoring Haruki Izumo’s urgent directive to deploy an Escape Stance and evade annihilation, he chose instead to intercept the attack, resulting in his LBX’s LOST status and subsequent academy expulsion. Shin openly affirmed his lack of regret, asserting his actions aligned with his duty-bound interpretation of platoon protocols. Post-expulsion, his final engagement occurred during a clash between Arata Sena and Rikuya, where he reaffirmed acceptance of his consequences as a necessary outcome of service. The DC Aerial operated on a Brawler-type armor frame at proficiency level 50, supplemented by secondary Knight, Strider, and Wild frames at diminished capacities. Unlocking Shin in affiliated media required story mode completion, with his LBX’s destruction underscoring narrative stakes tied to wartime allegiance.
