Background

Before arriving in the Star Rail universe, Kiana was a highly skilled miHoYo-game player. After completing a survey asking which world and character she wished to enter, she chose Honkai: Star Rail and Kiana Kaslana; she was subsequently transported into the role. 1

She awakened on Herta Space Station and spent roughly a month under Asta’s care while Herta examined her anomalous abilities. Herta classified Kiana’s power as a “Word of Law,” though she more bluntly called it an uncontrollable Jinx. 1

Kiana later joined the Astral Express as a Nameless. Her journeys repeatedly pull her into alternate worlds, dreams, memories, and identities connected to the Honkai, the Imaginary Tree, and people from her past. 336 384

Appearance

Kiana is a petite, white-haired girl with blue eyes. Her appearance changes frequently through her Jinx and Herrscher powers, ranging from childlike forms and disguises to forms modeled after other individuals. 277 127 177

• Her Herrscher of Finality form has golden, emotionless eyes, a golden halo, and purple-and-gold ceremonial attire. 172
• Her Herrscher of Thunder form carries a long saber, manifests lightning, and bears horns and red eye shadow. 122 126
• As Yae Sakura, she has retractable fox ears and gains abilities associated with that form. 177
• Her transformations can be stable enough to deceive observers, including when she imitates Herta, Yae Sakura, or the Xianzhou Marshal Hua. 23 262 274

Personality

Kiana is casual, humorous, and highly mischievous. She enjoys pranks, deliberately absurd lies, and provoking friends such as Silver Wolf, Bronya, Mei, and March 7th. 81 111 123 264

Despite her recklessness, she consistently protects people in danger. She fights Voidrangers to defend Herta Space Station’s researchers, prioritizes Mei over a confrontation with Welt’s clone, and supports allies from a distance when a direct battle would endanger them. 2 83 74

She can also be calculating when necessary. Kiana recognizes distractions in battle, manipulates Guinaifen into guiding her through Dreamtide Reef, and stages her own capture during the Inazuma conflict. 83 155 192

Kiana is uncomfortable with intense romantic attention and fears being trapped in romantic entanglements, a fear exploited by the Underworld Messengers’ illusion. 72

Abilities & Skills

Word of Law / Jinx

• Possesses multiple Herrscher cores. 241 247

Equipment
