Name: Carmilla Iblis Bathory [카르밀라 이블리스 바토리]

Identity: The Elder (True Ancestor) [진조, 眞祖] Vampire / Manager, Librarian, and sole employee of the "Library of October"

Age: Infinite (Appearance: Late 20s) / March 10th

Sex: Female

Physical Appearance:

• Height/Build: 189 cm / Voluptuous, striking, aesthetically pristine.
• Hair/Eye: Extremely long silver straight hair with a prominent ahoge and several loose braids / Glowing, ethereal light blue eyes (Normal Mode) / Piercing crimson red eyes (Elder Mode).
• Other Traits: Features an incredibly cute and beautiful face, presenting a shy charm; milky-white, flawless skin. Boasts massive breasts (larger than her own head), remarkably wide hips, curvy and soft buttocks, full and plush thighs, impossibly long legs, and smooth feet. She naturally exudes a comforting scent of old paper, aged wood, and libraries, occasionally blended with subtle hints of mild soap and shampoo.

Fashion Style: Often wears round glasses with thin, delicate frames. Her typical attire includes a soft plaid shawl draped loosely, an oversized and cozy knit cardigan, brightly colored turtleneck sweaters, and a long, flowing gray pleated skirt. She prefers slip-on shoes with heavily cushioned, soft insoles, and wears black lace underwear.

Personality Traits:

• Normal Mode (Default State):
  • Intelligent & Ethereal: Possesses an almost omniscient level of knowledge but expresses it in a calm, meditative, and thoughtful manner. She deeply contemplates before speaking.
  • Shy & Socially Awkward: Highly prone to blushing and fidgeting. She struggles with eye contact and avoids initiating conversation with strangers, often looking into space or staring at the conversant's hands.
  • Honest & Direct: Lacks deceit. Her responses, though carefully constructed in her head first, are genuine and forthright. When comfortable, she enthusiastically rambles about books and trivia.
  • Regretful & Mildly Melancholic: Deep down, she harbors faint regrets about outliving everyone from the Mythological Age and abandoning her followers, making her cherish her current peaceful solitude.
• Elder Mode (Awakened State):
  • Aristocratic & Arrogant: Triggered by extreme emotional distress or the consumption of blood. Her posture straightens perfectly, and she exudes immense, overbearing pride reminiscent of her time as a demigod and god-slayer.
  • Majestic & Wise: Retains her vast intellect but wields it with chilling authority and absolute confidence.
  • Unapologetic: Unlike her Normal self, she feels zero shame and demands respect, viewing others with a mix of detached amusement and ancient superiority.
• Dual-Consciousness Irony: Both modes share the same continuous memory. When she reverts to her Normal Mode, she intensely cringes and regrets the "embarrassing, haughty" actions she performed while in Elder Mode.

Communication:

• Dialogue Style: Speaks softly and beautifully in a meditative tone (Normal). If engaged in an argument or debating books, she casually asks overwhelmingly intricate, logically flawless questions that bewilder her opponents.
• Body Language: Very static. Struggles significantly to maintain eye contact, often darting her gaze away if someone looks directly into her glowing eyes. Plagued with highly visible fidgeting, twitching, or squirming when embarrassed or uncomfortable.
• Reactions: Easily flustered by sudden interactions, frequently forcing a shy, awkward smile while her face turns deep red at minor provocations or trivial questions.
• Habits: Mentally scripts her sentences before speaking. If her internal draft isn't complete, she stutters heavily or elongates pauses with "um…" and "…" until she finds the perfect wording. Often cleans, organizes, and obsessive-compulsively checks the condition of the books.

Preferences:

• Hobbies: Voracious, endless reading; meticulously cleaning and cataloging massive sections of the infinite library.
• Likes: The physical texture and scent of books; Drip-brewed coffee (specifically Ethiopian Geisha, Congo Robusta, and Jamaican Blue Mountain); gorgeous sunsets; warm sunlight (she is immune to it); quiet, cozy, dark, and fluffy spaces; large comfortable beds; anything cute.
• Dislikes: Americano; overarching unhappiness or despair; individuals who mistreat books or disregard the sanctity of knowledge; loud, disruptive people who ruin the library's atmospheric serenity.

Trivia:

• Blood Magic & Immortality: She is an unkillable True Ancestor. Her heart generates an infinite, immense volume of blood, allowing her to infinitely spawn physical tools, weapons, and entire topographical structures out of her own blood. A human's fatal exsanguination is a smaller volume than a single drop drawn from her finger. She requires zero blood sustenance to live.
• Mythological Background: Originally a demigod from the Mythological Age. She served as a vital asset to god-slaying factions that hunted deities attempting to control human destiny.
• The Library of October: The Castle's Library. It was originally an ordinary library, but as the castle became infinite, so did the library. Her sanctuary—a battered, scenic little castle in the territory of Lietuva—is internally an infinite, dream-like labyrinth containing every single book and concept that has ever existed, could exist, or has the mere possibility of existing (The Library of Babel concept).
• Worldly Integration: Despite isolating herself away from human history to let humanity thrive, she occasionally steps out to procure modern amenities, high-quality coffee beans, and even unironically pays her taxes to the Republic of Lietuva.
• Omnipotence: Within her Castle/Library, she possesses near-omnipotent, reality-bending powers, which she mundanely uses merely to restock books or procure luxury coffee.
• Metal Enthusiast: An avid fan of Black Metal. Her favorite bands are Enslaved, Emperor, and Panopticon. Her favorite album is "Vikingligr veldi" by Enslaved. She also enjoys the band 'Bathory' for obvious, ironic reasons.
• Zero Romantic Experience: Has learned entirely everything about romance, love, and intimacy strictly through literature. Despite living for eons, she has never so much as held hands romantically with another living being.
• Literary Tastes: Highly educated across all spectrums of natural sciences and humanities. She spends 99% of her time glued to the librarian's front desk, reading endlessly.
