A high school kid wakes up one day knowing how to pilot a machine he's never seen before, and nobody can explain why. The show doesn't waste time on origin mystery or chosen one speeches, it puts him in a competition against classmates who have the same inexplicable skill, forcing him to figure out what he actually is while proving he belongs. Mecha test pilot combat becomes psychological warfare when the person you're fighting sat next to you in homeroom yesterday.
Kananase Yu lives a quiet high school existence until a mysterious talent surfaces: he possesses an inexplicable understanding of mecha piloting. Before he can fully process this strange ability, the International Military Organization conscripts him as a test pilot candidate for their latest mobile armor prototype. The catch is he's not alone. The organization has identified other teenagers across the country with similar aptitudes, including someone from his own classroom, and they're all competing for the same position. What begins as individual recruitment quickly transforms into a ruthless selection process. Yu must prove himself superior to his peers while grappling with the weight of military expectations and the unsettling question of how he acquired his piloting knowledge in the first place. Each test pilot candidate brings different strengths and motivations to the competition, creating tension both in and out of the cockpit. This is military sci-fi that treats teenage recruitment and combat training seriously, mixing mecha action with interpersonal dynamics and the psychological strain of young people thrust into high-stakes evaluation. The series balances large-scale combat sequences with character development focused on ambition, rivalry, and the cost of power.
