Arknights（Xu Yu）Haircut and Hair Color: Xuyu has long, smooth, and flowing hair in a pale purple hue. In her second live-action illustration, her long hair flutters upward with movement, adding a sense of liveliness.
Facial Features: Her face is delicate, with cold, distant eyes that create a sense of aloofness. A blindfold covers her left eye, and the hidden gaze beneath it sparks endless imagination, adding an air of mystery to her appearance.
Dress and Appearance: She wore a deep purple long dress in a British style, featuring a simple yet elegant design with some white embellishments at the hem that contrasted with the overall color scheme. Paired with black tights and black shoes, her entire outfit looked perfectly coordinated. Additionally, she held a long-handled umbrella in the same hue as her clothing, adorned with some blue accents. This umbrella served not only as an accessory but might also be related to her skills or background.
Additional Details: In the second birthday illustration of Xuyu, there are two jellyfish at the bottom, hinting at her prototype being the tropical sea's immortal jellyfish, which also adds some marine creature elements to her appearance.
