Lubrum serves as a pilot within the Red Snappers, an elite all-female squadron aligned with the NESS faction. This unit acts as recurring adversaries to TERRA team pilots, engaging them in simulated space battles where defeated combatants are teleported to safety. Lubrum is one of four sisters forming the squadron, sharing a naming theme derived from words meaning "red" in various languages. Under the command of Captain Rouge, the Red Snappers are known as skilled opponents who frequently challenge TERRA pilots, including Yamamoto Yohko. Lubrum contributes to the squadron's collective objective: securing victories for NESS in planetary control disputes through non-lethal starship combat.
