Strain: Strategic Armored Infantry - S01

Eleven-year-old Sara Werec watched as her older brother, Ralph, was sent off to fight in an interstellar war 130 light years away. She promised herself she would become strong enough to stand beside him one day. Five years later, she enrolls at Grapera Space Armed Soldier Academy, training to pilot a "Strain"-an advanced combat system-as a Reasoner. During a surprise enemy attack on the academy, Sara faces a powerful Strain in battle and is swiftly defeated. The pilot removes his helmet and reveals himself as Ralph. Before vanishing, he slaughters the other students and destroys the school, leaving Sara shattered and questioning everything. Now, under a new identity, she returns to training, driven by one goal: to confront her brother and uncover the truth behind his betrayal.
