Description
Erin serves as secretary to the Althea Royal Guard commanders Alexandrov Grigorovich and Jail Murdoch. She has long hair typically tied in a braid, wears glasses, and dresses professionally. Her background reveals she is a childhood friend of Robert Du Vanvich. Both witnessed their parents killed by a Ballot Holder, including Robert's father, a Royal Guard soldier who failed to protect them. At the funeral, Alexandrov asked about their aspirations; Erin declared her desire for revenge and to become a soldier. Consequently, Alexandrov assigned Avsette Vremya to recruit her. As she matured, Erin's focus shifted from revenge to dedication in her secretarial role, and she developed romantic feelings for Alexandrov.

During the Special Service Arc, Erin coordinates access to Alexandrov and later delivers Jail's uniform per Alexandrov's orders after their duel. Following a coup framing Alexandrov for murder, she remains at the Royal Guard base under Robert's command but ultimately betrays him. She allies with Sakai Tokikaze and the Abyss to restore Alexandrov as Supreme Commander. During the Abyss invasion of Althea, she assists Tokikaze and cares for Abyss children. Captured by the White Special Service with the children, she is forced to cease communications to hide Gespenst Zerlegen's abilities. Later, under their orders, she reactivates communication, inadvertently exposing Nikola and Schmelman Bach's cruelty. Horrified by Schmelman's order to execute the children, she terminates the connection. Rescued by Jail Murdoch, she informs him of Gespenst Zerlegen's true identity as the seventh Baron.

In the Last War Arc, after Licht regains his Ballot Replica, Erin contacts him via her ability to confirm the Abyss children's rescue and attempts to locate Alexandrov. When Jail faces defeat against Robert, Alexandrov intervenes with Erin's assistance. After Alexandrov transfers his Ballot to Jail, Erin uses her ability to broadcast their fight against Robert globally. Post-Robert's defeat, she witnesses Alexandrov's surprise at Robert's conviction to "become like the wind." Three months later, she monitors the final battle between the Royal Guard and Special Service from a mountain with Alexandrov, relaying battlefield updates, including Jail's solo combat.

In the epilogue, set three years after the war, Erin appears alongside Jail and the revived Charles. Charles displays jealousy over her attractiveness, prompting Erin to remark that neither has a chance with Alexandrov, as Firenda "plundered" his heart before her death.
