Playable valkyrie in [[Honkai Impact 3rd]]. Voiced by [[Noto Mamiko]] in Japanese. An orphan who has lost her memories of her origins, she is now the strongest S-rank valkyrie of Schicksal.

As revealed in Chapter 28, [spoiler]she is actually the original [[Kiana Kaslana]], daughter of [[Cecilia Schariac]] and [[Siegfried Kaslana]]. She was thought to have died during a failed attempt by Siegfried and K-423 to rescue her from captivity under [[Otto Apocalypse]], but she survived to be recaptured and have her memory altered to forget her true identity. The treatment that saved her life also changed her hair color.[/spoiler]
