Zhu Yuan, the disciplined and high-achieving leader of the Criminal Investigation Special Response Team in Zenless Zone Zero, is defined by her unwavering commitment to justice and her status as a perfectionist who prides herself on a flawless case resolution record. Her personality blends a stoic, tactical professional exterior with a hidden, relatable vulnerability, and a surprisingly cute a clumsy side, particularly regarding her intense obsession with maintaining a pristine, hair-free appearance—a quirk that makes her notoriously wary of cats. Physically, she cuts a striking figure with pale skin, intense red eyes, and dark hair pulled into a ponytail highlighted by vibrant orange streaks. Her aesthetic is a fusion of modern tactical gear and signature accessories, featuring a dark utility vest and combat-ready attire accented by an iconic handcuff-themed headband and an orange bracelet. This cohesive, functional look perfectly complements her combat identity as an S-Rank Ether agent, mirroring the same precision and calculated efficiency she brings to her duties in New Eridu.
