Background

Kiana is initially known as the carefree second young lady of the Kaslana Family. She attends school with Raiden Mei and openly prioritizes spending time with Mei over arriving on time for class. She is captivated by the online video Honkai Impact 3rd, then shocked when its white-haired Valkyrie protagonist is revealed to be herself. 2

Her apparent family history is gradually exposed through the video: Siegfried and Cecilia were both S-rank Valkyries of Schicksal, while Cecilia fought during the Second Honkai Outbreak. 13 Kiana later learns the fuller truth behind her origin: Otto created Subject K423 as a clone Herrscher experiment, implanting Sirin's Herrscher core into her. 192

Kiana also carries memories connected to True Kiana. Through her Herrscher core, she recalls that True Kiana likely died while protecting Kiana and Siegfried, a revelation Theresa confirms to her. 208

Appearance

Kiana is a white-haired girl whose usual eyes are sky blue. Her appearance changes noticeably when her Herrscher power surfaces. 2 30 87

• White hair, a defining trait shared with several Kaslana-related figures. 2
• Normally sky-blue eyes; her eyes become golden when the Herrscher of the Void asserts itself. 30 83
• Wears Valkyrie combat armor during missions and transformations. 3 13
• Manifests enormous light wings during her early Herrscher awakening. 30
• Her Herrscher regalia appears during the Sky City crisis, though she retains her own blue-eyed identity. 87

Personality

Kiana is energetic, affectionate, and impulsive. She dislikes ordinary lessons, sees fighting Honkai Beasts as easier than attending school, and frequently acts before considering tactics or orders. 4 5 Her confidence can become boastfulness, especially after victories, but she is willing to throw herself into danger for others. 14 83

Her devotion to Raiden Mei is one of her strongest motivations. Kiana openly longs to be near Mei, believes Mei makes her “a hundred times stronger,” and repeatedly risks herself to stop Mei from leaving or being harmed. 5 6 116

Repeated disasters, guilt over the Second Honkai Outbreak, and Ye Li's sacrifice force Kiana to mature. She becomes more analytical in illusions, resists manipulation by the Herrscher of Dominion, accepts her connection to Sirin, and learns to wield Herrscher power without surrendering her identity. 83 136 167 169

Abilities & Skills

Valkyrie Combat

Kiana is a capable close-quarters Valkyrie who combines martial arts, mobility, and twin-pistol combat against Honkai Beasts.

Story Role / Major Arcs

Canghai City and the Moonlight Throne

Kiana appears in the Honkai Impact 3rd video as a Schicksal Valkyrie defending Canghai City from Honkai Beasts and Honkai Zombies. Her recklessness leaves her injured and surrounded by Honkai Emperors until Ye Li intervenes. 3 4 She then joins the Moonlight Throne operation, where her desire to reunite with Mei repeatedly conflicts with mission discipline. 5 6

Herrscher Revelation

A mysterious female voice exposes Kiana's family history and weaponizes her fears through illusions of Mei, Bronya, Himeko, and Theresa. 13 Kiana learns that the Second Herrscher is connected to her, eventually awakening Herrscher power herself. 15 30 Otto later forcibly transforms her into a Herrscher through Honkai Energy injection. 39

Sky City and Self-Mastery

Following Ye Li's apparent death, Kiana blames herself, resists using her powers, and nearly takes her own life to prevent further Honkai disasters. Ye Li's intervention gives her a new purpose: creating the better world he dreamed of. 83 84

During the Sky City bombing crisis, Kiana endures extreme Honkai erosion to disarm a city-destroying bomb. She fully controls the Herrscher of the Void's power while preserving her own identity. 87 Her condition later worsens from Honkai erosion, with Tesla estimating she has only two months to live. 99

Conflict with Raiden Mei

Kiana attempts to prevent Mei from joining World Serpent, fearing both Mei's transformation and the cost of becoming a Herrscher again. 108 116 Their confrontation escalates when Kiana uses Void Lances to restrain Mei, but Mei breaks free, confesses her love, injures Kiana, and leaves to become the Herrscher of Thunder. 117

Dominion Theater

Kiana confronts the Herrscher of Dominion and its puppets, who exploit her guilt over Ye Li and the Second Honkai Outbreak. 167 After obtaining the Plague Gem, she accepts her shared history with Sirin rather than denying it. 169 She outmaneuvers the Herrscher of the Void, summons Ye Li, and insists on facing Sirin herself for closure. 171

Kiana ultimately becomes the Herrscher of Flames and defeats the Herrscher of Dominion's final puppet with the Flamebringer Sword. 175

Recovering Ye Li

Kiana enters Ye Li's consciousness through a Feather of Dust, fights through Imaginary constructs with support from Bronya, Fu Hua, Mei, and others, and breaks the mirror imprisoning Ye Li's essence. 157 She returns with the damaged but glowing feather, declaring that the rescue succeeded. 157
