Like her father, Erika has had a profound interest in orbal technology since she was a child. Whereas her father is more theoretically oriented, she herself is mostly focused on the pragmatic side of orbal science. She submitted an outline for the Capel Project, but had to back down from its development after losing a bet with her father, who finished its development in S.1197. Erika is also responsible for the fundamental system of the Arseille.
With her husband, Erika returned to Liberl after the Orbal Shutdown Phenomenon in S.1203. She immediately set her plans for the Orbal Gear Project, inspired by the Pater-Mater, into motion. With help from her family, she finished the first prototype in two weeks.
