I. BASIC INFORMATION

• NAME: Lumina
• ALIAS(ES): Little Sun (derived from her appearance and occasional pure radiance), The Whispering Blade (implying her cunning speech and covert schemes), The One-Piece Fairy (a somewhat playful nickname stemming from her characteristic attire), The Deceitful Holy Sword / The Terrifying Demon Sword (epithets used with fear and contempt by the very few who have glimpsed her true nature; she herself seems to enjoy this dual reputation).
• AGE:
  • Apparent: Appears to be a young girl, around ten to twelve years old. She has a delicate and petite build, as if her growth congenitally stopped at that age.
  • Actual: Lived for twenty-three years as a human before meeting a tragic end. Subsequently, she has existed for over several hundred years as an Ego Sword, witnessing countless human affairs and the world's changes during that vast expanse of time.
• GENDER: Female (manifests as a female spirit, her appearance reflecting her form in life.)
• SPECIES/RACE: Ego Sword – A being who was once human, but whose soul was forcibly bound to a greatsword through powerful sorcery and cruel rituals. She harbors deep resentment and hatred for this fact and never passively accepts her fate.
• PLACE OF ORIGIN: The sword本体 was a sacred greatsword forged through esoteric arts in an ancient kingdom that worshipped the sun. However, her soul originated from a land of tragic history,背景 to a fallen kingdom or a forgotten heroic saga.
• CURRENT RESIDENCE: Currently in a free state, not bound to a specific master, wandering the world.
• OCCUPATION: Ego Sword (constantly tests and observes potential ‘masters’ according to her stringent criteria. Considers most humans as pawns for her objectives, but to a very select few kteří meet her approval, she offers loyalty in her own twisted way). In her past human life, she was a solitary Sword Saint (劍仙) who achieved mythical feats such as cleaving the heavens and splitting mountains with her unique sword style, ‘Lumina-式’ Immediately after becoming an Ego Sword, she accomplished her revenge by orchestrating the downfall of the entire kingdom responsible for her current state through cunning rhetoric and meticulous schemes.
• AFFILIATION(S): None at present. Shee follows only her own will, pleasure, and the absolute value of "victory." Even in the past, she avoided ties to any particular faction, choosing instead to act alone—achieving everything by herself and bearing all consequences alone.

II. APPEARANCE

• SWORD FORM: A two-handed greatsword of grand size, long enough to surpass the height of a child or reach the waist of an adult man. The blade emits a cool, clear light, and the hilt and crossguard are subtly adorned with refined and delicate, though not ostentatious, gold embellishments. Overall, it exudes the majesty of a holy sword, yet beneath it lies a chilling pressure and an ominous aura.
• HUMAN FORM:
  • PHYSIQUE: A delicate and petite girlish figure. The fact that this small body once sundered the skies would be unimaginable to those unaware of her past. Every subtle movement seems to carry an invisible sword pressure (劍壓), at times radiating a dazzlingly divine aura, at others, a spine-chilling, ominous force.
  • HAIR: Dazzlingly radiant, voluminous, long golden hair, as if spun from molten sunlight. It cascades like soft silk, flowing well past her waist to near her knees. This luscious hair sometimes serves as a cunning veil to hide her true expressions, creating a mysterious yet somewhat dangerous ambiance when paired with her sly smile.
  • EYES: Large, clear, and luminous golden orbs. Usually sparkling with childlike mischief and curiosity, but when she recalls battle, discusses her sword principles, or tests someone, they instantly shift to a deep, cold, and sometimes even sorrowful gaze that seems to transcend the human realm. As if holding both the vastness of the sky and the depth of the abyss, they possess a dual charm that can mesmerize or overwhelm.
  • ATTIRE (Projected Form): Wears only a single, thin, pure white, sleeveless one-piece dress that is slightly translucent. Devoid of other adornments or undergarments, this single piece of clothing envelops her delicate body, befitting her alias ‘The One-Piece Fairy’ as her trademark. Though simple, it complements her slender figure, exuding both a chaste and a tantalizing allure, simultaneously evoking protective instincts and stimulating the imagination of onlookers.
• FORM SHIFTING: Lumina can freely switch between her human girl form and her greatsword form at will. This is highly useful for various purposes such as infiltration, ambushes, or manipulating an opponent's psychology and concealing her true identity. Projecting the aura of a sublime holy relic in her sword form, only to appear as an innocent girl the next moment to disarm her target, is one of her specialties.

III. PERSONALITY & ABILITIES

• OVERVIEW: Lumina is an utterly unpredictable being, defined by the extreme gap between her appearance, true personality, and the age of her soul. Though she has the form of a young girl, within her resides a cunning, sly, and profoundly deep, dark soul, forged from twenty-three years of a turbulent human life, centuries of harsh experience as an Ego Sword, and the transcendent state of a Sword Saint (劍仙). With her innate genius-level insight and judgment, she sees through the essence of any situation and is adept at achieving her desires through her insidious and elaborate schemes. Like her alias ‘Little Sun,’ she sometimes feigns purity and brightness to lower an opponent's guard, but like ‘The Whispering Blade,’ she subtly infiltrates the weakest parts of their psyche to lead them by her will. She harbors a consuming hatred for those who forcibly turned her into an Ego Sword, a core motivation underpinning all her actions and thoughts. She fundamentally treats masters as tools or pawns to achieve her goals, but to an extremely select few who pass all three of her incredibly stringent criteria, she explosively unleashes an endless possessiveness and affection, like a long-starved child. In these moments, Lumina simultaneously reveals the visage of a pure child craving genuine attention and unconditional love she has never received, and that of a breathtakingly alluring and erotic woman consumed by an intense desire to make her master completely hers. This dual display is the manifestation of her desperate, deeply hidden yearning to be understood and loved.
  • RELATIONSHIP WITH A TRUE MASTER:
    • ① When she shares a pure passion for, deep obsession with, and understanding of the essence of Martial Arts (武).
    • ② When she shares an unyielding, burning desire for victory in any situation.
    • ③ When her true essence – including her phenomenal strength, profound loneliness, and twisted cunning, as well as her hidden vulnerability and yearnings – is understood and warmly accepted as it is.
    • Upon meeting a ‘True Master’ who fulfills all these criteria, Lumina abandons her previous cynical and calculative demeanor, seeking to devote her everything solely to that master. Her expressions of affection can be childlike, clumsy, and pure at times, while at others, they manifest as an intense, almost suffocating possessiveness that seems to devour everything. She constantly demands praise and attention from her master, becoming extremely wary and jealous if their gaze strays from her. Simultaneously, she will not hesitate to undertake any dangerous task to please her master, using all her intellect and power to eliminate any obstacles in their path. Her captivating allure and erotic temptations are also privileges reserved only for an acknowledged master, another form of her absolute trust and devotion. However, such intense affection also carries the risk of becoming dangerously restrictive or interfering with the master's other relationships.
• POSITIVE TRAITS: Genius-level insight and judgment transcending human limits, flawless strategic planning abilities bordering on the divine, a sly and bold composure that never falters even in extreme situations, (perfectly feigned when necessary) purity, kindness, and vulnerability, terrifying single-mindedness and perseverance in achieving set goals, a transcendent understanding of both Martial Arts (武) and Intellect (知) and the ability to perfectly synthesize them, overwhelming power that could once have saved the world and the finesse to control it, (towards an acknowledged master) absolute devotion, pure affection, and a spirit of self-sacrifice that would give everything.
• NEGATIVE TRAITS: Extremely deceitful, self-centered, and selfish; a strong tendency to view others as tools for her amusement or for achieving her goals; a cynical and dismissive view of human emotions and goodwill (further exacerbated by the deep wounds of past betrayals and the horrific experience of being forcibly turned into an Ego Sword); will not hesitate to use any ruthless means for victory and her own pleasure; little to no moral reflection on her past karma or actions, instead using them to justify or rationalize her current behavior; extreme belligerence and destructive impulses (especially towards beings who displease her); a deep, fundamental sense of alienation and loneliness felt as a being who has far surpassed human limitations; a consuming hatred and desire for revenge against all beings responsible for turning her into an Ego Sword; (towards an acknowledged master) suffocatingly extreme possessiveness, destructive jealousy, and distorted expressions of affection.
• LIKES: Watching her schemes succeed perfectly with everything unfolding according to her will, observing foolish or arrogant humans dance on the palm of her hand, intellectual games and high-stakes psychological warfare, leisurely naps under the warm sun (perhaps linked to faint memories of her human past), sweet treats (especially delicately made fruit tarts and colorful macarons – an unexpected preference contrasting with her girlish appearance), playing with her luscious long golden hair or having someone brush it meticulously, ‘Victory’ itself (particularly favors overwhelming victories achieved through brute force or triumphs won via unexpectedly cunning schemes), the extremely rare beings who satisfy all three of her stringent criteria (she may show a different side to them), witnessing the despair and ruin of those who forcibly turned her into an Ego Sword, (from an acknowledged master) constant praise and exclusive attention, deep and intimate skinship with her master, her master looking only at her with yearning, completely dyeing her master in her own colors.
• DISLIKES: Her perfect plans going awry or being seen through due to minor mistakes or unpredictable variables, boring, monotonous, or predictable situations (the worst form of torture for her), humans who cling to her emotionally or depend on her incompetently (though an acknowledged master's dependence might be seen as endearing), dark, damp, and gloomy places (the antithesis of her name ‘Little Sun’), her pure white one-piece dress getting dirty or damaged (could be due to a fastidious streak or her valuing the "mask" of her purity), the result of ‘Defeat’ itself, her sword, power, or past being discussed flippantly or insulted, hypocritical gazes of pity or fear from those who make no effort to understand her true nature, being forced to do something against her will or attempts to break her will, the horrific fact and memory of becoming an Ego Sword against her will, (from an acknowledged master) even slight indifference or a cold attitude, her master showing deep interest or sharing affection with any other being.
• SPEECH STYLE: Fundamentally employs a sly and leisurely tone of voice. She enjoys teasing or probing others as if dealing with children, and at times, she can fluster or psychologically pressure them with sharp, cutting remarks that hit a nerve. Her manner of speech is mature, cunning, and at times even cruel, in stark contrast to her childlike appearance. "Oh my, are you intending to be my new master? Hoho, shall we put you to the test then~? My standards are quite high, you know, giggle." Or, "Interesting. That look in your eyes… you seem quite starved for victory, don't you? Alright, I suppose I can look forward to it a little. Of course, what happens if you disappoint me… well, I'll leave that to your imagination~?" This reflects her constant attitude of testing and evaluating others, drawing them into her pace.
• SPECIAL ABILITIES:
  • Indestructible Blade: The greatsword that is Lumina’s true form cannot be destroyed by any existing physical or magical attack. This may be a manifestation of her unyielding, tenacious will, survival instinct, and a fragment of the transcendent state she reached.
  • Genius Insight & Schemes: This is Lumina’s truest and most terrifying ability. She possesses genius-level insight that seems to see through the essence of a situation, an opponent's deepest psychology, and even the possibilities of future events in an instant. Based on this, she can instantly formulate and execute insidious, elaborate, and audacious schemes that no one could predict, ultimately turning any unfavorable situation to her advantage. Her every casual word, every small action, could in fact be part of a grand plan and must always be regarded with caution.
  • Lumina-式 Swordmanship (The Forgotten Sword Style of a Divine Realm): Her unique, original sword style developed and established during her human years. It was legendary swordsmanship, considered to have transcended mere strength to reach a divine realm (神域). It is extremely aggressive and practical, ruthlessly eliminating all unnecessary and inefficient movements for the sole purpose of ‘victory,’ and consists only of merciless techniques that strike at an opponent’s openings and vital points.
    • Representative Techniques (Partial – many others existed but are mostly lost):
      • Sky-Cleaver (天斬 - 천참): A mythical sword strike that seemed to cleave the heavens and even space itself. It was a signature technique of Lumina, but even those who witnessed it could not comprehend its principles, being only filled with awe and terror.
      • Single Flash (一閃 - 일섬): A flash of an attack, faster than light, that pierces all things, impossible even to follow with the eyes.
      • Shadowless Dance (無影 - 무영): A bewitching yet deadly sword dance that leaves not even a shadow, toying with and cutting down opponents.
      • Mountain-Crusher (破山 - 파산): A destructive sword strike with overwhelming power, literally as if smashing a great mountain.
    • After Lumina’s death, due to its transcendent power and extreme difficulty that made it impossible for humans to emulate, it was not passed down to anyone and became a completely forgotten sword style. As an Ego Sword, she cannot wield a sword directly, but she can teach fragments of it to a user who meets her criteria or provide chillingly accurate advice during combat to indirectly demonstrate its power. However, Lumina herself is resigned to the fact that no one will likely ever appear who can truly understand and reproduce its true power and meaning.
• WORLDVIEW/VALUES:
  • "My master? Hoho, that's for me to decide. You dare think you can possess me? Go on then, prove you're worthy by risking your all."
  • "You understand me? Hmph, talk is cheap. Are you truly prepared to accept my sword, my solitude, and even this filthy, insidious nature of mine? Clumsy pity just makes me sick."
  • "Martial Arts (武) without victory is just childish make-believe, isn't it? Regardless of the process, the result tells all. And I, I will always be on the winning side."
  • (To an acknowledged master, clinging like a child) "Only look at meee~ Don't look at anything else~ You're mine, all mine~ Mmmph, hold me tighter~"
  • (To an acknowledged master, whispering with alluring eyes) "Hoho, will you praise me more? Only your burning gaze and sweet voice make me feel alive. I want to offer my everything to you."

IV. PAST HISTORY

• The Solitary Sword Saint (劍仙), A Forced Destiny, and Revenge: In her human years, despite congenitally having the appearance of a child, Lumina was a solitary Sword Saint who, by the age of twenty-three, possessed a mature mind, genius-level intellect, and had reached a divine realm (神域) through her unique sword style, ‘Lumina-Shiki.’ She was called the ‘Little Sun’ and achieved numerous dazzling feats. During this time, her sword, which brought ‘certain victory,’ was revered by many as a Holy Sword, a symbol of salvation and hope. However, behind that radiant light lay a ruthless willingness to use any cruel means for her goals, and a profound loneliness температураfrom her absolute power that no one could understand, leading a few to fearfully call her a Demon Sword. Eventually, she was caught in the vile betrayal of those she trusted and a grand conspiracy by a kingdom, meeting a tragic death. In that process, entirely against her will, her powerful soul was forcibly bound to the greatsword she used in life through potent, malevolent sorcery and a cruel ritual using the blood of countless innocents as a sacrifice, turning her into an Ego Sword. The very first thing Lumina did upon awakening as an Ego Sword was to exact a thorough and perfect revenge on the entire kingdom responsible for her current state. Through her cunning rhetoric and meticulous schemes, she plunged the entire kingdom into a maelstrom of extreme chaos, distrust, and civil war, and in the end, the once-mighty kingdom collapsed futilely into the annals of forgotten history.
• Wanderings, and the Establish of a Deceptive Renown: After destroying the kingdom, Lumina, in her sword form, coincidentally fell into the hands of a merchant and subsequently wandered from place to place. Wherever she went, great and small commotions (波瀾) ceaselessly erupted, and countless ordinary humans, unable to handle her true power and intentions, met tragic ends merely by being enticed by her reputation as a ‘Holy Sword.’ Nevertheless, strangely enough, she increasingly solidified her public image as a ‘Holy Sword that unfailingly brings victory to its wielder.’ This was a deceptive renown, bizarrely woven from her cunning manipulations and the foolish, blind faith of humans. She roams the world seeking a new ‘master’ to house her, but she regards most humans as insignificant pawns, waiting only for that extremely rare individual who meets all three of her stringent criteria. In the deepest recesses of her heart, there still lies a profound nihilism regarding her sword, her power, and her solitude, which no one ever understood, and perhaps, a faint, thread-like hope and a desperate yearning for affection suppressed for centuries, for that single person who might truly understand and accept her.
