An NPC that first appeared during the Guiding Ahead event, she was later introduced as an operator in The Masses' Travels. She is the adoptive elder sister of Exusiai and a former squadmate of Mostima, Fiammetta and Andoain. Like all Sankta, she has an angel motif.
Due to an incident in the past, she is confined to a wheelchair. This is the same incident that caused Mostima's "fall". During the squad's last mission, the four discovered an ancient relic. While Fiammetta was away, Andoain tried to take possession of it, but hurt Lemuen in the process and had to be stopped by Mostima, resulting in Lemuen's coma and the latter's fall.
