Lambda is a Dark Elf with platinum hair, a sharp golden eye, the other eye closed, beautifully plump lips, with a tall stature and refined muscles from years of military training.

A former military officer in the Velgalta Empire, she's a strict instructor and harsh towards trainees, given her background and to ensure they are up to whatever tasks soon follow. As a member of Shadow Garden, she's obedient towards her superiors. Even though she is feared by the Numbers, she acknowledges hard work.
