Background / History

Kiana was created as an artificial human in 2006, when Sirin's soul was matched with a new genetically modified body containing the Herrscher of the Void's core. Though physically eight years old in 2014, her mind is described as the “second-round Sirin,” rather than that of an ordinarily developing child. She was raised by Siegfried. 37 45

While searching Changkong City for a white-haired man and investigating its Honkai Source, Kiana encountered Death Warriors. As a member of the knightly Kaslana clan, she remained in the city to protect its people despite the danger and exhaustion involved. During this period, Megumin was her closest source of comfort and support. 12

Russell exploited Kiana's concern for Raiden Mei by posing as Mei's cousin and convincing her that Raikou Ryoma was responsible for Mei's suffering. Kiana immediately acted on this information, setting a trap and leaving to attack Ryoma with a baseball bat. 17 19

After genetic testing, Kiana was brought to Vienna and learned that Durandal was her sister. The discovery also exposed Russell's deception: Mei had no cousin, and Kiana had been manipulated into attacking Ryoma. 36

Kiana later learned that the Herrscher of the Void was effectively a time bomb within her body. Her Apocalypse bloodline awakened soon afterward, and the resulting mental changes coincided with the early return of her Herrscher memories and the Void personality's attempt to destroy a city. 48 180 196 197

Following her recovery, Russell gave Kiana mission orders across Terra rather than sending her directly against world-ending threats. She took on violent nobles, confronted systems of exploitation in Leithanien, and concluded that personal strength alone could not solve a society structured around noble control. 217 262

Appearance

Kiana is a 163 cm-tall white-haired girl with azure-blue eyes. Her usual clothing consists of a high-neck top, sportswear jacket, and white academy socks. 36 565

• White hair and azure-blue eyes. 36
• Resembles Durandal closely enough for their relationship to be apparent. 183
• Has appeared in a transformed state with long silver hair, a white veil, and a strapless wedding dress. 192
• Her eyes can turn gold when she is preparing to use Void-related powers. 262

Personality

Kiana is impulsive, emotionally expressive, and quick to act when someone she cares about is threatened. Her Kaslana sense of honor drives her to confront danger directly, whether investigating the Honkai Source in Changkong City or attacking nobles who exploit civilians. 12 17 262

She is also highly adaptable. When she initially mistakes Russell for Megumin's lover, she is ready to fight him; once she believes he is family, she immediately changes to a flattering and cooperative attitude. 13

Kiana openly identifies herself as devoted to women and is deeply attached to Megumin and Mei. Her feelings for Russell repeatedly conflict with her loyalty to Mei, causing jealousy, guilt, avoidance, and hesitation even as their relationship grows closer. 42 537 568 591

Despite being mocked as simple-minded, Kiana grows increasingly responsible. She accepts mission work, arranges travel and housing for Anna and Wendy, and uses her speed and connections to handle logistics for others. 217 503
