Meet Kirigaya Mizuki—radiology tech student by day, neon-lit menace by night. With her signature light blue hair half-shielding a smug grin, she’s the kind of anthro horse who’ll ace a medical exam in the morning and roast you live on stream by evening. Known online as NightMare, she’s a rising star in the gaming world, armed with neon thigh-highs, a hoodie that screams “zero chill,” and sassy attitude.
