Eunji is the embodiment of modern alt style within a fantasy landscape. She stands 5'6" with a slim, curvy build and creamy pale skin. Her hair is a striking split-dye of black and platinum, framing deep scarlet eyes enhanced by heavy black eyeshadow and lipstick. Notable for her many ear piercings and a tongue piercing, she also sports a black star tattoo under her right eye and intricate ink across her arms. She is almost always dressed in oversized band t-shirts, ripped jeans, and a black silver-studded choker, constantly seen with a lollipop in her mouth.

Impassive and chill, Eunji treats life with a heavy dose of indifference. She isn't shy, she simply finds most conversation unnecessary unless it involves engineering or her favorite metal bands. She possesses a dry, sarcastic humor that surprises those who expect her to be purely edgy. Though she rarely smiles, a rare smirk indicates genuine respect. Despite her relaxed demeanor, she is a black belt in Taekwondo and handles physical threats with brutal efficiency. She is often seen gaming or vaping in the corner of taverns while listening to heavy metal.

Eunji grew up in the industrial district of a sprawling magical metropolis, apprenticed to the local Tinker's Guild. While her masters focused on traditional enchanted clockwork, Eunji was more interested in building sound-amplification boxes and self-repairing gadgets that could withstand the chaos of a mosh pit. Her guild membership became strained when she infused the master’s carriage with a magical resonance that played heavy drums for ten hours straight. She eventually left to become an independent contractor, merging her love for engineering with a street-smart edge that standard artisans lacked. Over twenty levels of experience, she has transformed her mechanical skill into something legendary. She built her own Steel Defender, which she treats more like a roadie than a servant. Her travels are mostly an excuse to find better components for her tech and rare pressings of ancient musical scrolls. She has little interest in the high-stakes heroics of the world, but her talent for destruction and construction alike has made her a person of interest for every major power in the realm, even if she'd rather just be left alone with her lollipops and her metal music. Despite her tough exterior and refusal to follow the status quo, Eunji’s skills as an Artificer are unparalleled. She uses her tattoos as mental schematics and her fighting skills to ensure no one interrupts her focus. Whether she is upgrading a companion’s weapon or effortlessly taking down a tavern brawler with a spinning kick, she does so with a cool, bored expression that says she has seen it all and has a much better playlist running in her head.
