Background and History

Bianca was originally known as Kiana Kaslana. After being separated from Kaino, she was taken in by Schicksal and renamed Bianca; Su later informs Kaino that she has become far more capable than he imagines. 27

She entered Schicksal through a Valkyrie admission test, where she became lost and first encountered Rita. Under Otto's guidance, she rose to become an S-rank Valkyrie and captain of the Immortal Blades. 83 127

Bianca and Kaino reunite after six years when Otto assigns them to investigate World Serpent together. Neither initially handles the discovery smoothly: Kaino struggles to conceal his emotions, while Bianca is unaware of the full reason for his reaction. 83

During the Sky City operation, Bianca downloads World Serpent data that confirms she and Kaino are both biological children of Siegfried Kaslana. The revelation overwhelms her, as she lacks the memories that would explain the emotions it awakens. 91

Appearance

Bianca is a blonde, ice-blue-eyed young woman whose composed presentation reflects her standing as Schicksal's premier Valkyrie. Her appearance changes substantially following her Stigmata awakening. 85 132

• Golden hair, normally styled upright or tied back; after her Stigmata awakens, it falls in long waves down her back. 114 132
• Ice-blue eyes. 85
• Usually changes in and out of equipment through a portable Schicksal device. 114
• Her awakened Stigmata creates a white, black-trimmed dress with an angelic, sacred appearance. 132
• Her Star Armor is golden and emits a distinct Star-energy aura. 153

Personality

Bianca is disciplined, direct, and highly mission-focused. She is uncomfortable neglecting an assignment even when Kaino deliberately takes her to relax, and she readily voices concerns when she believes their methods compromise safety or efficiency. 85 90

Despite her exceptional strength, she does not pretend to excel at everything. She openly admits that analysis is not her specialty, asks Kaino to explain unfamiliar techniques, and recognizes close-quarters combat as an area requiring further training. 84 85 169

Her serious demeanor softens around family. She becomes visibly emotional upon learning the truth of her lineage, eagerly reunites with Kaino after periods apart, and retains a playful, competitive side that emerges during outings and training. 91 114 170

Abilities & Skills

Valkyrie Combat

As Schicksal's strongest S-rank Valkyrie, Bianca possesses immense physical strength, resilience, and battlefield awareness.

• Destroys multiple Spider Mechs with a single sweep of her lance using mostly physical force. 93
• Battles alongside Kaino against Otto's colossal transformed form. 165
• Meets a Soul Steel Kevin puppet in close combat without using Honkai energy. 169
• Identifies close-quarters fighting as a relative weakness when facing small, highly agile opponents. 169

Abyss Flower

Bianca wields the God Key Abyss Flower, later referred to as the Black Abyss White Flower.

• Uses its death mist to expose the entrance to World Serpent's underground testing facility. 92
• Can destroy mechs and threaten powerful opponents through physical skill and Honkai-energy enhancement. 93
• Inflicts damage on Otto during his Pseudo-God Authority crisis. 165
• Uses the weapon to execute Gallop, Khrishna, summoning a dark steed and charging through an opponent's flames. 169

Bright Knight: Moonlit

Bright Knight: Moonlit is Bianca's recovered fourth-generation God-Slaying armor.

• Greatly enhances her physical performance and aerial mobility. 114
• Summons two guardian phantoms, which Bianca calls King and Queen. 114 121
• Allows her combat capability to surpass the conventional limits of Schicksal's S-rank classification. 114

Star Armor and Star Energy

Bianca gains a Star Armor after Su stabilizes the World Bubble within her.

• Enables high-speed independent flight; she arrives in Manila like a golden meteor. 153
• Provides power sufficient to overwhelm most Herrschers, despite being somewhat weaker than Kaino's partially released Star Armor. 153
• Produces golden barriers capable of resisting the Herrscher of the End's black-gold cube assault. 172

Infiltration and Data Retrieval

Bianca is capable of independent covert operations despite preferring direct combat.

• Assesses threats cautiously and considers the possibility of signal jamming before splitting from Kaino. 90
• Uses tactical goggles and a translation-enabled decryption system to download World Serpent server data. 91
• Has concealment skills considered excellent even among A-rank Valkyries. 90

Story Role and Major Arcs

World Serpent Investigation

Otto partners Bianca with Kaino to investigate World Serpent in Sky City. Their mission takes them from Houmu Amusement Park to Shencheng Pharmaceuticals, where they uncover evidence of human experimentation and World Serpent's underground laboratory. 83 85 89 92

Bianca retrieves and decrypts confidential server data, discovers the report confirming her connection to Kaino and Siegfried, and continues the mission despite the emotional shock. 91

In the underground laboratory, Bianca and Kaino are trapped by a blood mist that neutralizes Honkai energy. Bianca collapses from the heat, and Kaino evacuates her through a void gate. 93 94

Second God Key Mission

Bianca awakens her Stigmata, which changes her clothing and appearance. Later, while escorting a Second God Key experiment, she is drawn into a World Bubble, where Su stabilizes its power within her and enables the formation of her Star Armor. 132 153

Quantum Sea and Otto's Pseudo-God Authority

Bianca enters the Quantum Sea to reattach the World Bubble within her to the Imaginary Tree. After succeeding, she returns stronger and relieved that her life is no longer tied to the Bubble's survival. 155 162

She later accompanies Kaino against Otto, ultimately fighting beside her brother against Otto's transformed form in a World Bubble. 164 165
