An NPC in [i][[Arknights]][/i] introduced during the Guiding Ahead event. She is the adoptive elder sister of [[Exusiai (Arknights)|]] and a former squadmate of [[Mostima (Arknights)|]] and [[Fiammetta (Arknights)|]]. Like all Sankta, she has an angel motif.

Due to an incident in the past, she is confined to a [[wheelchair]]. [spoiler]This is the same incident that caused Mostima's "fall"; their superior officer attacked her while being controlled by Mostima's staff. Mostima shot him to protect Lemuen, but as she deliberately broke one of the Sankta's commandments she was transformed into her current fallen state.[/spoiler]

She has [[long hair|long,]] [[pink hair]] and [[pink eyes]], a simple white, circular [[halo]], and white [[energy wings]] that strongly resemble her sister's. She carries a small [[character doll]] of Exusiai and a [[sniper rifle]].
