Sasaki

Sasaki serves dual roles as Chief Development Director and Maintenance Division Head at Toha Heavy Industries, overseeing both the operational upkeep of the Tsugumori-class Guardians and the research into next-generation units. Renowned for her exceptional technical mastery, she holds an almost obsessive standard for machine integrity—pilots who return their units damaged can expect a hands-on lesson delivered via her signature oversized wrench. As one of Sidonia's highest-ranking crew members privy to classified intelligence, Sasaki operates as the unseen pillar sustaining the ship's combat readiness and long-term survival.
