Background / History

Otto Apocalypse identified extraordinary potential in Kiana's bloodline: the Kaslana family's physical constitution, Schariac holy blood, and exceptional latent ability. Unable to fully decipher the Kaslana bloodline, he began the secret K-Series cloning project. After 422 failures, K-423 awakened carrying Sirin's consciousness and became the new Herrscher of the Void. 1347

Kiana later lived with Siegfried, who gave her the name Kiana Kaslana. When the Herrscher of the Void awakened, she attacked Siegfried and severed one of his arms. 1361

At St. Freya Girls' School, Kiana was notorious for failing five subjects and ranked poorly in academics despite her combat potential. She became close to Raiden Mei and Bronya, eventually appearing alongside them in Chaldea's first Spiritron Transfer operation. 580

Appearance

Kiana is a white-haired girl whose usual appearance is youthful and expressive, often with her hair in signature braids. After regaining control of her body from the Herrscher of the Void, one of her eyes becomes gold while the other remains blue; Fu Hua later helps her conceal this heterochromia except when using Herrscher power. 1076 1100 1101

• Snow-white hair; originally worn in braids. 1076
• Normally sky-blue eyes; one eye turns gold when her Void power surfaces. 1100 1101
• Often wears battle-damaged third-generation White Comet Valkyrie armor. 1101
• A later mature form features a white combat outfit, high ponytail, and crimson greatsword. 1139
• Her complete Herrscher of the Void form retains blue eyes marked by cross-shaped pupils. 1160

Personality

Early on, Kiana is cheerful, excitable, playful, and intensely proud of appearing in the Light Screen footage. She loves games, skips explanations in favor of action, and is frequently mocked by Bronya for her poor academics and simplistic reasoning. 580 581

She is openly infatuated with Mei, often clinging to her, praising her cooking, and treating even past-life revelations as evidence that she is destined to win Mei's heart. 580 1057

Kiana's encounter with the Herrscher of the Void changes her profoundly. Believing herself responsible for the Great Honkai Eruption and Murata Himeko's death, she becomes withdrawn, self-loathing, and suicidal before accepting Fu Hua's help. 1100 Her later maturity is rooted in responsibility rather than coldness: she investigates threats independently, protects civilians anonymously, and accepts the burden of Herrscher power without allowing it to define her. 1101 1141

Abilities & Skills

Valkyrie Combat

Kiana is an exceptional close-quarters fighter despite her weak classroom performance. Fu Hua trains her through dream-based Shenzhou combat methods and willpower exercises. 1100 1322

• Reaches S-rank Valkyrie-level practical combat ability. 1101
• Rapidly adapts to an opponent's style during combat. 1322
• Uses Fu Hua's techniques and guidance to locate enemies hidden by illusions. 1322
• Can fight effectively even while wearing damaged mass-produced armor. 1101

Authority of the Void

Kiana inherits the Herrscher of the Void's authority and gradually learns to wield it without surrendering control to its consciousness. 1101 1160

• Performs short-range spatial movement and passes through physical barriers. 1101 1160
• Uses space manipulation for mobility, infiltration, and combat repositioning. 1101 1160
• Initially treats the authority as support rather than a primary fighting style. 1101
• Her early spatial movement is far weaker than the original Herrscher of the Void's. 1101
• After defeating Sirin's hostile consciousness, she can use the authority without her eyes turning gold. 1368

Multi-Core Herrscher Powers

Kiana carries multiple Herrscher cores and Gems, giving her access to more than one authority at severe physical cost. 1158 1160

• Uses the Gem of Conquest to manipulate electromagnetic force and purple lightning. 1160
• Uses the Gem of Haste's flames in battle against the Herrscher of Domination. 1368
• Fuses five cores to become the Herrscher of Flamescion. 1370
• Her body deteriorates under the strain of multiple Herrscher powers; she eventually loses the ability to feel pain, allowing injuries to worsen unnoticed. 1158 1171

Mental Resilience

Kiana repeatedly fights within consciousness spaces against the Herrscher of the Void, the Thousand Herrschers, and despair induced by human malice. 1358 1362

• Resists attempts to turn her into a puppet of the Herrscher of Domination. 1369
• Draws strength from memories of those who helped and trusted her. 1362
• Defeats the Herrscher of the Void's consciousness and accepts her connection to Sirin. 1347 1368

Relationships

• Raiden Mei — Kiana's closest companion and the person she openly pursues. Kiana saved Mei from suicide after her first Herrscher awakening, becoming Mei's salvation; their bond endures separation, conflict, and Mei's eventual return of the Gem of Conquest. 1056 1174 1389
• Bronya — Friend and frequent bickering partner. Bronya calls Kiana an idiot or paramecium, but repeatedly fights beside her and enables Kiana's Flamescion transformation. 580 1057 1370
• Fu Hua — Mentor, guide, and trusted ally. Fu Hua stops Kiana's suicide attempt, trains her to resist the Herrscher of the Void, and later guides her against the Herrscher of Sentience. 1100 1322
• Murata Himeko — Teacher and enduring source of strength. Himeko's sacrifice devastates Kiana, but her encouragement helps Kiana reclaim herself and overcome the Herrscher of the Void. 1100 1160 1362
• Durandal / Bianka — Sister figure and fellow Valkyrie. Kiana is described as a clone derived from Durandal's genes and Sirin's, and the two later stand together against Otto. 1384 1389

• Rita Rossweisse — Temporary ally during the Sky Dome City operation. Though Rita initially intends to use Kiana as bait, they cooperate against Divine City Pharmaceuticals and World Serpent. 1148 1154
• Raven / Natasha Shiora — Enemy whose hatred of Kiana stems from the Herrscher of the Void destroying Raven's island during a Honkai disaster. 1155 1176
• Kevin Kaslana — An overwhelming threat Kiana calls “Ancestor Kevin.” She refuses to flee Sky Dome City despite learning of his power. 1153 1154
• Siegfried — The man who gave Kiana her name and lived with her before the Herrscher of the Void's awakening injured him. 1361
