Source: 2.5 Dimensional Seduction (2.5次元の誘惑 / Ririsa)

Character Description:
Hoshizuki Yoki is a distinct character from the cosplay-focused series 2.5 Dimensional Seduction. Visually, she cuts a highly memorable and edgy figure with her long black hair—often styled with strands falling between her eyes—sharp sanpaku grey eyes with noticeable bags underneath, subtle freckles, and a prominent set of sharp teeth. Her everyday look is sharp and professional, consisting of a full black suit paired with a black necktie and black pants, accented by her signature round eyewear. When switching to her summer or swimsuit aesthetic, she undergoes a bold transformation, utilizing a half-updo with braided accents, hoop earrings, tinted eyewear, and an extremely daring halterneck slingshot swimsuit that highlights her fierce and uninhibited presence.
