She's part of the original Immortal Ship Committee, former Gardes pilot, and best friend to former ace pilot Hiroki Saitou. She left the committee after Hiroki had a fall out with them. Lala is now the "dorm mother" to Sidonia's cadets. Due to her bond with Hiroki, she took personal interest in looking after Nagate Tanikaze.
