Sophie serves as a dedicated subordinate to Beevee Liscar, a former elite Seven Knight from the Unification War. She wields knives effectively in close combat and excels as a highly skilled sniper. Her appearance features short blond hair and olive eyes, typically clad in a green or three-quarter length coat during operations.

Her actions consistently advance Beevee Liscar's objectives. She participated in high-stakes missions, including the artificial fairies transaction with Wolfran Row. During the ambush on a train transporting a Fairy Weapon, she initiated the attack by standing on the tracks and shooting the driver. In the ensuing fight, she engaged Dorothea agent Marlya Noel, nearly defeating her before intervention by another Dorothea agent, Oz Mare, halted her.

Sophie later accompanied Beevee during an assault on a convoy led by Ray Dawn. When Beevee fought Ray Dawn and then Nein Auler, he ordered Sophie to surrender her fairy weapon to Nein Auler to ensure a fair duel. Following Beevee's death in this confrontation, Sophie approached his body and closed his eyes. She then aimed her weapon at Nein Auler. Dorothea's Third Unit, led by Lily Heineman, arrived and opened fire. Sophie attempted to return fire but was shot and died at the scene.

Throughout these events, Sophie exhibits unwavering loyalty to Beevee Liscar, including expressing willingness to die for him. Her combat roles consistently involve both precision sniping and direct engagement.
