As a punishment decreed by the Roman Catholic Church, she alongside all of the members of the Agnese Forces and several other subjects are taken to the Queen's Fleet of La Regina del Mare Adriatico, although she did not receive the same treatment as sisters Lucia and Angelene.

She became the helmsman of ice ship #47 during the La Regina del Mare Adriatico's mobilization along with its fleet. As the helmsman, she performed the duties of patrolling nearby areas for incoming attacks and is required to report to Bishop Biagio Busoni regularly.
