International Police Force
Lightning The Argent
There is no other background information on Solaria except that she's Marina's biological sister. Her singing awakens the Gear cells within the system of the people who drank the Blackard's Vitae and causes them to mutate. Dozens of villagers die mysterious, violent deaths because of this. Later in the story, her singing awakens the dormant Megadeath class Gear Hydra that destroys the village (the people had already been evacuated.). Sol finds her but her innocence stopped him from killing her; instead, he gave her his limiter. After the incident, she comes under the protection of the International Police Force.
- Solaria is the only Command Type Gear who has never intentionally killed anybody in any timeline unlike Justice , Dizzy and Valentine .
- Her background gives a slight possibility that she's the Maiden of the Grove .
