Power Progression

Background / History

Vivian and Greg Sass first formally met at eight years old during a gathering arranged by their parents. Close ties between House Sass and the royal family encouraged the match; the children played together, learned court etiquette, and eventually became engaged 89 175.

Their relationship deteriorated as Greg’s home became entangled with the Demon King Cult and he responded to fear and disappointing magical aptitude with self-destructive behavior. Vivian repeatedly tried to help, but he rejected her concern. At fifteen, he drunkenly humiliated her before other young nobles, after which she asked the king to dissolve their engagement 175.

At the Academy, Vivian built her reputation through exceptional discipline rather than royal privilege alone. She was the only first-year student in the preceding decade to earn top marks in every year-end subject and win election as a Student Council officer. Her ice magic subsequently earned her the position of Second-Year Top Student 83.

Original-Game Fate

• Narrative role: A female villain, neither a romanceable heroine nor a major supporting ally 61.
• Cause of decline: Increasing pressure from Lilith’s superior magical talent eventually leads to a breakdown, followed by temptation or coercion into joining the Demon King Cult 61.
• Transformation: Fuses with Demon blood to obtain power and becomes an enemy of the protagonists 61.
• Fixed ending: Turns to darkness and dies in every original-game storyline, regardless of players’ attempts to save her through affection or hidden events 61.
• Lilith’s route: Victoria and Lilith defeat her; Vivian delivers her dying confession in Lilith’s arms 61.
• Sisterly conflict: Her opposition to Lilith’s friendship with the common-born Victoria is a major original-game flashpoint. Unaware of Victoria’s identity as the hero, Vivian suspects ulterior motives and seeks to protect royal reputation 113.
• Possible outside manipulation: Greg later suspects that Melina used the Fallen Mother’s authority to influence Vivian in the original story. This remains his hypothesis, not a confirmed account 404.

Appearance

• Hair: Waist-length, lake-blue or ice-blue hair, usually arranged in a carefully maintained high ponytail 60 83.
• Eyes and complexion: Ice-blue eyes, extremely pale skin, and delicate features repeatedly compared to ice and snow 60 83.
• Bearing: Tall, straight posture and precise royal etiquette; her usual expression is cool and reserved 60 83.
• Academy uniform: Superior fabric and tailoring, a short dark-blue cape, and a silver Student Council President’s badge at her collar 60.
• Combat clothing: Dark-blue short mage’s robe over a black high-necked top, fitted trousers, and knee-high leather boots 433.

Personality

Vivian is exacting, self-disciplined, and strongly duty-oriented. Her schedule is planned to the minute; she reportedly begins meditation and physical training at four each morning. Her meticulous notes receive private praise from professors, while her stern presence makes fellow Student Council members careful about their conduct 83 101.

Her administration is impartial: nobles and commoners alike are judged by Academy regulations and their actions. She has challenged well-connected professors and refuses to let her broken engagement justify Greg’s public humiliation or bullying 83 106. This fairness coexists with traditional aristocratic assumptions, particularly her original-game suspicion of Victoria’s friendship with Lilith 113.

Beneath her composure, Vivian is deeply sensitive to being surpassed or abandoned. Lilith’s rapid progress makes her question the limits of effort, while Greg’s sudden strength leaves her afraid that he deliberately ruined his own prospects to escape their engagement. Her fear is not merely wounded pride: she cannot bear the possibility that her existence suppressed someone else’s potential 83 167.

Romantic experience is initially unfamiliar to her after a life centered on study and training. She earnestly follows advice about giving “rewards” and accepts that she has some tsundere traits. However, she also misapplies that idea to Greg, interpreting his denials of affection as evidence of hidden love 177 193 241 287 288.

Her renewed relationship with Greg gradually makes her warmer and more secure. She stops expecting exclusivity but wants a lasting place in his heart. Later, she becomes openly affectionate in private and accepts Lilith’s superior talent, though jealousy over Greg remains 287 355 421 446.

Abilities & Skills

Ice Magic

Vivian specializes in precise battlefield control and concentrated attacks against vulnerable points 181.

• Ring of Frost: Freezes the ground into slippery ice, disrupting charges and slowing groups of enemies. An opponent can avoid the main affected area 181.
• Ice Wall: Blocks attacks and divides the battlefield. One demonstrated wall is half a meter thick and two meters tall; sustained fire attacks require continued mana investment to preserve it 181 210.
• Ice Shield: Provides rapid protection against breath attacks and fire spells. Its durability varies with the opponent: the Frost Giant Lizard breaks through it, whereas Juno’s restricted-match attacks leave it intact 182 283.
• Rapid-Fire Ice Spears: Fires multiple arm-thick projectiles at weak points such as eyes and mouths, combining piercing damage with freezing effects 181.
• Ice Crystal Spike Formation: Produces a fan of destructive spikes. Its Converge application gathers them into a spiraling ice drill 181 182.
• Ice Crystal Spear: Condenses mana into a powerful thrown weapon; she uses it against the Throat of Longing and to pierce a Frost Giant Lizard’s exposed throat 186 443.
• Ice weapons and restraints: Can create longswords, a two-handed sword, and a ring of ice that immobilizes an opponent’s feet 190 191 283.
• Environmental manipulation: Condenses airborne moisture into attacking crystals, freezes Greg’s water blade into explosive ice fragments, and clears a passage through a burning building 209 317.

Combat Tactics and Coordination

• Serves as the main frontline controller during her monster-horde battle with Greg, alternating barriers, slowing effects, and targeted attacks while he supplies potions and supporting fire 181.
• Coordinates with Greg without verbal instructions, including their combined water-and-ice counterattack against flanking cultists 317.
• Defeats Juno in a restricted sparring match; neither participant uses her full strength 283.
• Studies the Frost Giant Lizard in the Library after nearly dying to one. In their later encounter, she draws its bite into a stone pillar, freezes its teeth there, and strikes the exposed, unscaled throat 443 444.

Limitations

• Ice resistance: Her ordinary attacks initially do little against the Frost Giant Lizard’s scales. In their first encounter, Greg reduces its resistance before her converged spike attack lands; the passage attributes its death to an instant-death check rather than her ice magic alone 182.
• Mana expenditure: Maintaining extensive defenses against phantoms causes visible exhaustion. Her successful solo lizard attack consumes all her remaining magic power 323 443.
• Physical vulnerability: She has some ice resistance but an ordinary human body. Distraction leaves her exposed to a Piercing Beetle ambush, and the Throat of Longing overwhelms her defenses and inflicts serious internal injuries 179 182 190.

Academic and Domestic Skills

• Produces highly organized notes with detailed annotations and obscure references 83.
• Handles substantial Student Council paperwork and mediates disputes over work assignments 101 339.
• Lives independently and manages her own daily needs. Her cooking includes precise, practiced knife work 436.

Equipment / Items

• Student Council President’s badge — Silver badge worn at her collar 60.
• Ice-patterned notebook — Leather notebook embossed with ice-crystal patterns, normally filled with meticulous lecture notes 167.
• Sword — Used to wake Greg during her visit to his Dungeon camp; its properties are not specified 89.
• Dark-blue apron and wooden hairpin — Worn while preparing dinner at the underground camp 436.

Relationships

• Greg Sass — Childhood companion and former fiancé, later her romantic partner and Dungeon companion. Their renewed bond helps her escape her original-game fate; they keep their intimacy discreet because exposure could cause him trouble 175 289 355 446.
• Lilith Kahn — Younger paternal half-sister. Vivian’s protective strictness and insecurity over Lilith’s talent initially strain their bond. She later seeks reconciliation and asks Lilith for advice on efficient mana use, while remaining wary of her feelings for Greg 60 83 386 440 446.
• Yelina — Student Council colleague who respects Vivian’s effort and supports her relationship with Greg. Later trusts Greg to handle his relationships with both Vivian and Victoria 101 118 418.
• Victoria — Fellow combatant and romantic rival. Vivian is uncomfortable with her closeness to Greg, but later accepts her participation in camp construction and cooks alongside her 203 418 436.
• Juno — Sparring partner whose interest in taking Greg to the Ember-Eyed Tower provokes Vivian’s jealousy. Her teasing also tests Vivian’s patience 283 287 394.
• Ellie — Challenges Vivian over abandoning Greg after their engagement ended. Vivian explains that she kept trying until she could no longer justify it to herself and now wants to remain beside him 243.
• Sylvia — Another woman close to Greg; privately resents Vivian for having been with him first and confronts her with a hostile look at camp 430.
• Olivia — Academy Head whose orders bring Vivian to Greg’s camp to address his skipped classes. Vivian later supports Olivia’s Dungeon training-camp plan as an opportunity to grow stronger 89 90 404.
• Melina — A potential threat identified by Greg. Melina’s own observations suggest that Vivian’s former emotional vulnerability no longer matches her intelligence 239 404.
