Yoko Machi

Born to a family of fishermen, this mysterious figure originally discovered Kokopelli's cave and initially resisted joining the contract. Though her true identity as Koemushi's sister was hidden, she possessed deep knowledge of the pilots' rules and shared a telepathic bond with her brother. Driven by the exhaustion of witnessing endless cycles of suffering, she eventually sacrificed her neutrality to become a pilot, stepping in to protect Jun and alter the destined course of the conflict.
