“If I can identify and encapsulate a fragment of memory before it's unveiled to the world, those solitary moments of delight are my most favored and unique memories.”

“A sweet-tempered and elegant scholar. Member #81 of the Genius Society. An expert in the biological sciences.

She earned Nous' attention with her talent and terrifying perseverance, and began her research on the origin of life in a secret corner of the universe.

For that, she was invited by Herta to collaborate with Screwllum and Stephen to develop the Simulated Universe.

Secretly, she greatly enjoys traditional theater and desserts, and she is also very interested in embroidery.”

Black Swan is a 5-star Wind character on the Path of Nihility. Her kit revolves around the unique Sacrament debuff that she applies and has good synergy with other DoT effects. Her Sacrament debuff has multiple stacks and can deal DoT and other additional effects to the enemy.

Black Swan's first official appearance was in Version 1.0, in the Myriad Celestia Trailer – Fables of the Stars Part 1 video. More recently, she also appeared in the Game Awards 2023 Candidacy Video as the storyteller recapping the journey of the Trailblazer. Now, a year since her first official appearance, Black Swan is finally becoming playable in Honkai Star Rail.
