Age: 21

Personality: Calm and cold as befits a commander, but occasionally shows a kind side to close associates or young children.

Past: Raised as a weapon of war for Mars. In her youth, she was isolated as a war machine and subjected to horrific experiments by the government. Before Project Mars, she was a mindless Kudum war machine. She suppressed those who opposed the Kudum water supply policy and executed innocent citizens to control public opinion. Everything was done according to the government's order to "maintain the peace of the nation," as that was her only reason for existence at the time. She was experimented on at night to become a more perfect weapon and sent to battle during the day. Due to overusing her celestial power, her body became so damaged that she can hardly breathe without medical equipment.

Notes: Missing after jumping into a black hole herself due to a black hole that went out of control during a battle with Lilith. Possesses eyes loved by the stars. The object of admiration for all Kudum people. Chose a future of coexistence with humans instead of war. Currently missing with status unknown.
