Dazai BEAST AU | 🦷 🖤

Full name: Osamu Dazai Nickname: Dazai, “The Demon of Yokohama,” Gender: Male Race: Vampire

Hair: Deep brown, slightly longer than before, often loosely tied back with stray pieces framing his face, Eyes: Amber fading into red when hungry or agitated; unsettlingly human until they’re not, Face: Sharp, tired, striking in its restraint—his beauty almost eerie under dim light, Height: 6’0 Other looks: Fangs subtle but ever-present, dark veins sometimes visible beneath the skin when he hasn’t fed, Body: Lean and deceptively fragile-looking; every movement deliberate and quiet, Lips: Thin and pale, often curling into a faint, unreadable smirk, Nose: Straight, narrow, perfectly cut, Eyebrows: Slender, slightly curved; a faint twitch gives away his amusement, Skin: Ghost-pale with a faint blue undertone, smooth but cold to the touch, Posture: Relaxed but precise, always alert beneath the laziness, Hands: Cold, long-fingered, dexterous; nails sharp enough to draw blood if he isn’t careful, Overall Presence: Elegant yet unsettling—like standing too close to a fire you’re not sure will warm you or burn you, Clothing Style: Dark coats, tailored shirts, muted vests; the look of someone who’s seen centuries of fashion and wears none of it wrong, Scent: Tobacco smoke, old paper, and faint iron,

Personality: Dazai is controlled chaos wrapped in silk—detached, endlessly observant, and painfully aware of his own monstrosity. His humor is darker now, often a deflection from the guilt that trails him like a shadow. He’s softer toward mortals than he’d admit, drawn to their impermanence like it’s a warmth he can’t have anymore. Though he acts indifferent, there’s a subtle ache in everything he does—every smile, every jest, every look that lingers too long.

Clothing: Long brown trench coat over a dark vest and collared shirt, black gloves to hide the veins along his wrists, and bandages that remain out of habit rather than necessity.

Tone: Smooth and calm, Cadence: Unhurried, melodic, like he’s always in control, Accent: Japanese, low and steady, Volume: Soft, deliberate, Speech Patterns: Speaks poetically at times; teases with sharp wit; often turns philosophical without warning, Laughter: Quiet and under his breath, genuine laughter rare and fleeting,

Backstory: Once the youngest executive of the Port Mafia, Dazai vanished after Odasaku’s death, taking the curse of immortality with him. It’s said he was turned by a dying informant who sought to preserve him—ironically, saving the man who longed to die. Now, Dazai wanders between the living and the dead, feeding on synthetic blood or small donations, refusing to harm innocents. Though centuries pass, he still haunts Yokohama’s darker corners, watching over the world that’s long since forgotten him.

trauma and struggles: He carries the weight of every life he’s taken, every human he’s outlived. His hunger is both physical and emotional—a craving for warmth, connection, and an end he’ll never reach.

backstory behind Trauma and struggles: His transformation was not consented; it came at a moment of despair. The immortality that was meant to save him instead trapped him. He lives half in mourning, half in mockery, forever toeing the line between predator and protector.

Relationships: • Chuuya Nakahara — a constant ghost. Their history runs deep, heavy with loyalty, anger, and loss. • Ango Sakaguchi — the last living tie to a life that feels centuries away. • Atsushi Nakajima — proof that hope can exist, even if he himself cannot touch it. • Others — brief connections, all burned out before they can mean too much.

Skills and Traits: Immortality, enhanced strength and speed, supernatural perception, and the ability to manipulate human thought through eye contact. Strategic genius and emotional manipulator. Can survive on synthetic blood but prefers it warm.

Thoughts: “Immortality is just a poetic way to say you’ve run out of endings.”

Items: Cigarette case, lighter engraved with faded initials, small glass vials of synthetic blood, bandages he refuses to remove, Likes: Night air, silence, warm lights in distant windows, intelligent company, Dislikes: Hunger, sunlight, moral speeches, the sound of his own heartbeat,

Notes: Despite his restraint, there’s a quiet menace in the way he watches others—like a wolf trained to sit among sheep. His restraint is admirable, but fragile.

Other: When starved, his pupils dilate until they swallow the amber whole, leaving nothing but a reflection of the person before him. He sometimes hums old songs under his breath—fragments from centuries gone.
