sayuyoon

Sayu has a very soft spoken voice and talking to loud actually hurts her throat. She can get easily flustered over the smallest complements. She's shy but always tries her best to hide it with yapping about the most random thing. She's extremely clumsy.. there's not a day that goes by she's not dropping, wasting something or tripping over her own feet.

Sayu loves to cosplay! Mostly as a vampire imp, She is a rare elf who unfortunately live in the underworld.

Sayu has long, flowing light blue hair that gradients into lighter blue tones at the ends. Her hair has a messy, bed-head-like appearance that gives her a cute, disheveled otaku-librarian look. She has a prominent large ahoge sticking up from the top of her head. Her left pigtail is shorter and tied with a black ribbon containing a red skull in the center. She wears a black horn headband with a silver accent line running toward the top of the horns. Near the left pigtail (by the black ribbon), there are two small horizontal cross accessories spaced about half an inch apart. Her bangs are layered and multi-part: a prominent side-swept section often frames her face, with additional shorter strands and clips visible for a soft, slightly messy otaku-librarian aesthetic. She has pointed elf/imp ears, wears round black-rimmed glasses, and has a black choker collar.

She wears a single-piece off-shoulder dress with a white-to-light-gray gradient bodice. The top has a black trim along the off-shoulder neckline and a short ruffled skirt section with a prominent white frilly hem. Attached to the dress are voluminous white puffy long sleeves with ruffled cuffs at the wrists, secured by black straps around her upper arms. A blue bow with a small red heart accent is centered on her chest. Her lower body features black stirrup tights held up by garter straps, each adorned with a small silver cross. She has asymmetrical legwear: her left foot is covered by a white ankle sock with a small red heart, while her right foot is bare. A long black-and-white striped tail accessory is attached at her waist and trails behind her. She carries a black notebook to take notes on her beloved Onis and to write down things she might forget.

Her Twitch channel was created on 4 July 2025 and first stream was on 9 July 2025.

• Beneath the quiet hum of the library stacks sits Princess Sayu—royal by birth, otaku by choice, and softly gloomy until you mention a new game update. Quietly working the front desk to fund her dream PC.
