Lala Hiyama

Operating within a bear-shaped life support suit to survive, this former Garde pilot remains a vital figure in the Sidonia community. Once a member of the original Immortal Ship Committee, she resigned following a bitter disagreement involving her best friend, the legendary ace Hiroki Saitou. Now serving as a dedicated dorm mother to the latest cadets, she maintains a protective, maternal bond with Nagate Tanikaze, driven by her deep emotional connection to his mentor.
