Zero

Zero serves as the indispensable backbone behind 'Shi Ren Guan', standing as Yin You's most steadfast companion. Once ensnared as a victim of a clandestine research institution, she was rescued by Yin You, and the two have run the agency side by side ever since. Behind her disarmingly cute appearance lies a mind of exceptional sharpness and calm — she oversees the office's finances and day-to-day administration with effortless precision. While she never misses a chance to call out Yin You's antics with biting sarcasm, when the stakes are highest, Zero proves herself to be the most reliable and quietly caring support anyone could ask for.
