Reika Nanjou was once regarded as one of the most gifted pilots in the Arandoth military, driven by a conviction that warfare should never demand the ultimate sacrifice from its soldiers. She devoted herself to the development of an autonomous drone combat system, envisioning a future where machines bore the cost of battle instead of human lives. Eight years ago, however, a catastrophic malfunction during a U-Link system trial forced her to make an irreversible choice—she gave her own life to prevent a swarm of rogue units from causing widespread harm to others. Though the military buried the truth of her death, her sacrifice became the silent force shaping her younger brother's journey and leaving a profound mark on those around him.
