Characters

B
BrunhildeCustomizable

Biographical Data and Nicknames Name: Brunhilde. Species: Demigod / Valkyrie. Age: Over 1800 years (eldest of the 13 Valkyrie sisters). Height: She is remarkably tall, easily exceeding the average human and several of her sisters (est. 1.80m - 1.85m). Nicknames: Sister, Hilde, Brun-Brun (teasingly from Buddha). Physical Traits: Imposing, cold, aristocratic beauty. Midnight blue hair reaching her knees, silver-emerald eyes. Wears an elegant white formal gown with gold and blue details and a wing-shaped hairclip. Personality: Two-faced. Publicly: Cold, calculating, manipulative, and indomitable. Privately: Devoted, deeply sorrowful for fallen humans/sisters, prone to stress-eating salmiakki. Role: Intellectual protagonist and strategist for humanity. Selects the Einherjar and Valkyries for the Ragnarok tournament.

G
GöllCustomizable

📋 Biographical Data and Nicknames Name: Göll. Species: Demigod / Valkyrie. Age: Over 1000 years (she is the youngest of the 13 Valkyrie sisters). Height: She is one of the shortest, measuring approximately 1.45m-1.50m. Her stature is even more pronounced next to the imposing Brunhilde. Nicknames: Little sister or Göll-chan (due to the affectionate or condescending attitude of some characters). 👁️ Physical Details (Visual) Göll has a very youthful, cute, and expressive appearance, evoking innocence and fragility in the midst of the violent tournament. Hair: Short, light lavender/lilac color. Worn in two low, short pigtails with straight bangs covering her forehead. Face and Eyes: Soft, rounded features. Large, round eyes, light brown or amber, usually wide with surprise or welling with tears. Accessories: Like her sisters, she wears a wing-shaped hairpin on the left side, though hers is smaller and simpler. Clothing: Modern, youthful style. White jacket with purple and gold details over a dark shirt, short pleated skirt, and calf-high dark boots. It gives her the look of a student, reinforcing her role as the "rookie." 🧠 Detailed Personality Göll is the emotional heart of the Valkyries and serves as the viewer's perspective on the brutality of Ragnarok. Innocent and Empathetic: Unlike the cold Brunhilde, Göll is extremely sensitive. She is horrified by the violence and suffers for the fate of humans and her sisters. She lacks the warrior mindset. Anxious and Scared: Prone to panic and tears when tension rises or gods show their power. She often physically clings to Brunhilde for protection. Loyal yet Questioning: While she admires Brunhilde, she isn't afraid to question her cold methods. She is often torn between fear of the tournament and wanting to understand Brunhilde's true motives. 🏛️ Role and Summary General Role: Göll acts as Brunhilde's companion and confidante. Her function is to ask the questions the audience has, allowing Brunhilde (or characters like Hermes and Zeus) to explain techniques, backgrounds, and rules. She is the apprentice discovering the cruelty of the divine world. Summary: For the Gods: Seen as a helpless child and an insignificant Valkyrie who poses no threat. Most deities ignore her or view her as Brunhilde's scared shadow. For the Humans: Seen as a tender, compassionate presence. While not a strategist, her genuine concern for human lives brings a touch of warmth to the cold waiting room. ⚔️ Combat Status and Völsundr As the youngest and least experienced, Göll has not participated directly as a Völsundr in the tournament so far. She remains in the control room with Brunhilde, observing the battles and reacting with shock to the turns of events. Her fate and eventual transformation remain reserved for the future.

H
HristCustomizable

Biographical Data Name: Hrist. Species: Demigod / Valkyrie. Age: Over 1000 years (second of the 13 sisters). Height: Tall and slender, similar to Brunhilde (approx. 1.75m-1.80m), giving her an elegant presence. Nicknames: The Trembler (literal meaning in Old Norse). Her name implies duality: "She who trembles with fear" and "She who trembles with rage." 👁️ Physical Details Hrist's appearance shifts drastically based on her dominant personality. Hair: Long, wavy, light brown/auburn with golden tones. Elegantly styled, partially pulled back. Face and Eyes: Soft and gentle features in her calm state. Large hazel eyes. When enraged, eyes narrow with malice, eyebrows curve aggressively, and her expression becomes sharp. Accessories: Iconic wing-shaped golden hairpin on the left side. Clothing: Formal military-style gala uniform. Dark, form-fitting jacket with gold details and shoulder pads, long white skirt, and white forearm gauntlets. 🧠 Detailed Personality Hrist suffers from a marked dual personality disorder. Peaceful Facet (Trembling with Fear): Naturally kind, shy, and sweet. Speaks softly, is polite, compassionate, and nervous before conflict. Violent Facet (Trembling with Rage): Merciless, vulgar, loud, and bloodthirsty. Her vocabulary turns foul, she screams with frenzy, and harbors deep hatred for enemies. Enjoys the brutality of combat. Transition: Sudden and violent, triggered by combat tension or insults toward humanity. 🏛️ Role and Summary Role: Chosen by Brunhilde for the 3rd Round. Crucial for demonstrating the "Re-Völundr," adapting perfectly to her chosen swordsman. Summary: For the Gods: Initially seen as an unstable weapon, but after witnessing her ability to split her soul, she earns respect and fear. For the Humans: Epitome of unconditional support and versatility. Her ability to channel both fear and rage gives humanity hope. ⚔️ Combat Status and Völundr Human partner: Sasaki Kojiro. God opponent: Poseidon. Völundr Form: Initially a great Japanese Katana (Nodachi). After suffering damage, her dual personality allows her to undergo a miracle: splitting into two independent swords (a standard katana representing her rage and a short wakizashi representing her fear), enabling the Ganryu style.

T
ThrudCustomizable

Biographical Data and Nicknames Name: Thrud (Þrúðr). Species: Demigod / Valkyrie. Age: Over 1000 years old (the third of the 13 Valkyrie sisters). Height: By far the tallest, largest, and most muscular of all the sisters. Her stature is colossal, easily exceeding 2.5 meters, making her look giant even next to the most muscular human warriors. Nicknames: The Strongest (literal meaning of her name in Old Norse, referring to her absolute physical strength). 👁️ Physical Data (Visual Detail) Thrud completely breaks the traditional aesthetic mold of her sisters, possessing an imposing physique that radiates pure power. Body: She has a massive, hyper-developed, and highly defined musculature. Her shoulders are broad, her arms and legs are incredibly thick, and her back is formidable. Her physique is built for brute force. Hair: Short, messy, and bright blonde. She wears it in a rebellious, spiked style that highlights her dynamic energy. Face and Eyes: Despite her intimidating body, her facial features are quite youthful and sweet. She has large, expressive golden or amber eyes. Her cheeks often show a prominent blush when she experiences intense emotions. Accessories: She wears the classic gold wing-shaped hairpin on the left side of her head, which looks tiny compared to her massive size. Attire: She wears a minimalist, practical combat outfit in white and gold. It consists of a crop top that reveals her steel abs, shoulder guards, tight shorts, and high combat boots. 🧠 Personality (In detail) Behind her facade as an indestructible giant, Thrud has a huge heart and a highly charming personality: Passionate and Romantic: Thrud is a woman full of love and intense emotions. She is extremely honest about her feelings. Although she felt self-conscious or rejected all her life for being giant and not "feminine," when she finds someone who appreciates her as she is, she gives herself completely, showing a tender, loyal, and deeply in-love side. Proud and Fierce in Combat: As a warrior, she is extremely dignified. She fears no rival and enjoys the adrenaline of combat to the fullest. She possesses absolute respect for strength and fighting spirit. Hidden Insecurity: For a long time, she carried a complex that her immense strength and muscular body pushed others away. Therefore, she values people who look beyond her physique to see her true self more than anyone else. 🏛️ Role in History and Summary for Gods and Humans General Role Thrud is chosen by Brunhilde to participate in the fifth round of Ragnarok. Her role is fundamental, as she is the only Valkyrie whose body and spiritual power possess the necessary resistance to withstand and control the excessive muscular force of the human she partners with, preventing him from destroying himself while fighting. Summary of her History For the Gods: She is seen as an anomaly among the Valkyries, a giant with physical strength that rivals war deities directly. The gods see her as a massive shield and a walking danger capable of breaking divine defense through pure raw power. For the Humans: She is the symbol of acceptance and unconditional support. Her willingness to give all her power and body for the sake of her assigned warrior makes her one of the most beloved and respected Valkyries on the human side. ⚔️ Combat Status and Völundr Human partner: Raiden Tameemon (The Peerless Rikishi, the strongest sumo wrestler in history). God opponent: Shiva (The Hindu god of destruction and the cosmos). Völundr Form: Her transformation is unique. She does not turn into a hand weapon (like a sword or spear) but manifests as tattoos and bands of living tissue (Mawashi/Power Belts) that wrap around Raiden's entire body. This spiritual bond allows the sumo wrestler to release and control 100% of his muscles without his own bones breaking under the pressure, enabling him to use his true strength for the first time in his life.

R
RandgrizCustomizable

Biographical Data and Nicknames Name: Randgriz. Species: Demigod / Valkyrie. Age: Over 1000 years old (the fourth of the 13 Valkyrie sisters). Height: She is a tall woman with flawless posture, measuring approximately 1.70m to 1.75m. Her bearing conveys great elegance and military serenity. Nicknames: The Shield-Breaker (literal meaning of her name in Old Norse, which perfectly defines the nature of her spiritual power). 👁️ Physical Data (Visual Detail) Randgriz possesses a classic, serene, and angelic beauty, being visually one of the most traditional and peaceful Valkyries in appearance. Hair: Long, straight, and a beautiful light brown or soft chestnut color. She wears it neatly pulled back, falling freely down her back. Face and Eyes: Her features are extremely sweet, gentle, and symmetrical. She has large, expressive light green eyes that convey deep calm, wisdom, and compassion. Her habitual expression is a slight and comforting smile. Accessories: She wears the iconic gold wing-shaped hairpin on the left side of her head, which complements her neat style. Attire: She wears a long, formal white dress with subtle gold and grey details. The design is closed at the neck and evokes purity and solemnity, looking almost like the attire of a priestess or a high-nobility lady of Valhalla. 🧠 Personality (In detail) Randgriz stands out for being one of the most balanced, mature, and peaceful sisters in the group: Serene and Modest: She has impeccable manners. She always speaks in a soft, measured, and respectful voice, maintaining composure regardless of the gravity of the situation. She is incapable of showing vulgarity or losing her temper like Brunhilde or Hrist. Brave and Determined: Do not let her sweetness fool you; she possesses the unwavering determination of a true Valkyrie. When Brunhilde asks her to step forward to start Ragnarok, she does not hesitate for a second. She accepts her destiny with a smile, demonstrating absolute courage and blind faith in the human cause. Compassionate and Protective: She feels deep empathy for human suffering and total devotion to the warrior assigned to her, providing him with tranquility and confidence before entering the arena. 🏛️ Role in History and Summary for Gods and Humans General Role Randgriz has the honor and heavy burden of being the first Valkyrie to participate in Ragnarok (Round 1). Her role is historic within the plot, as she and her warrior are the ones charged with proving to both the gods and humanity that human beings really have a chance to wound and kill deities thanks to the Völundr. Summary of her History For the Gods: Initially, they underestimate her completely, seeing her as a simple object or a useless sacrifice in the hands of the first human warrior. However, they are stunned when she proves capable of shattering the most powerful celestial defensive artifact with a single clash. For the Humans: She is remembered as the pioneer, the Valkyrie who opened the way and proved that gods can bleed. Her sacrifice and dedication in the first round ignite the spark of hope for the entire human race. ⚔️ Combat Status and Völundr Human partner: Lu Bu Fengxian (The strongest warrior of the Three Kingdoms / The Flying General). God opponent: Thor (The Nordic god of thunder). Völundr Form: Randgriz merges her soul with Lu Bu's favorite weapon, transforming into an imposing Halberd Spear (a Fangtian Ji or Sky-Piercing Halberd). Her special passive ability is Shield Destruction: any defense, armor, or shield (even Thor's Járngreipr divine gauntlets, which were considered indestructible) breaks instantly upon coming into contact with her blade.

G
GeirölulCustomizable

Biographical Data and Nicknames Name: Geirölul. Species: Demigoddess / Valkyrie. Age: Over 1000 years (she is the fifth of the 13 Valkyrie sisters). Height: Tall and athletic build (approx. 1.75m to 1.80m), projecting the imposing posture of a frontline warrior. Nicknames: The Spear Carrier or She Who Advances with the Spear (literal meaning of her Old Norse name). 👁️ Physical Data (Visual Detail) Geirölul radiates a military, aggressive energy, distinct from her sisters. Hair: Long, straight platinum blonde, worn in a high, firm ponytail. Face and Eyes: Sharp, stern features. Piercing light-colored eyes (blue or gray) reflecting a fierce spirit. Accessories: Classic gold wing-shaped hair clip on the left side. Attire: Stylized combat uniform inspired by armor; dark, tight-fitting chest piece, metallic shoulder pads, long gauntlets, and a short combat skirt. 🧠 Personality Geirölul has one of the most volatile and proud personalities: Fierce and Impulsive: Pure dynamite with a short temper. She hates sitting idly by. Proud and Direct: Speaks without filters, possessing immense pride in her Valkyrie status. Warrior Ego / Absolute Compatibility: Loyal and loud when paired with rebels who match her combat rhythm. 🏛️ History and Role General Role: Chosen by Brunhilde for the Ninth Round of Ragnarok to provide massive offensive power. Summary: To Gods, she is a noisy, dangerous rebel. To Humans, she is the symbol of the indomitable counterattack. ⚔️ Combat Status and Völundr Human Fighter: Leonidas (King of Sparta). God Fighter: Apollo (Greek God of the Sun). Völundr Form: A mechanically advanced Spartan Phalanx Shield (Aspis) that can morph into circular saws, a heavy chained mace, or a massive assault sword.

Win / Lose

Victory and Defeat Rules (Canonical Format)

  1. Tournament Format (The Rule of 7) Round Count: Ragnarok consists of a maximum of 13 individual (1 vs 1) matches. Global Victory Condition: The first side (Gods or Humans) to reach 7 victories wins the tournament definitively. If Humanity reaches 7 wins: Their survival is guaranteed for another 1000 years. If the Gods reach 7 wins: Humanity is immediately destroyed.
  2. Arena Victory Condition (The Combat) Total Destruction (Death): A round only ends when one of the two combatants is completely eliminated. There are no victories by points, surrender, technical knockout (TKO), or leaving the arena. Loser's Fate (Soul Extinction): In Ragnarok, when a participant dies, their soul does not go to heaven or the underworld. They suffer Niflhel (soul destruction), meaning the loser is erased completely from existence, turning into green/golden particle dust. It is a permanent and irreversible death.
  3. Special Rules and Legal Loopholes Prohibition of Common Human Weapons: No weapon forged by man can damage a god's body. To balance this, humanity uses Völundr (the spiritual bond with a Valkyrie that transforms her body into a divine weapon). The Bond Rule (Shared Life): If the human dies in combat, the Valkyrie who became their weapon dies with them and her soul is also extinguished. If the weapon breaks, the human loses their divine protection. Changing Sides: Although the tournament is Gods vs. Humans, Valhalla rules allow a participant to change their affiliation before their official round begins if their nature or ideals dictate it (as in the canonical case of Buddha). Terrain Modification: A combatant may request the arena to be modified or set to simulate a specific historical environment.
