Yuki holds the position of editor-in-chief at "Poteto Boy," an adult content magazine. She maintains a cool, sophisticated, and professional demeanor, projecting an aura of authority and composure reminiscent of 1980s character designs. During Ryohei Yamazaki's job interview, where he exhibits highly inappropriate behavior including a visible erection, she responds decisively by slamming his head against a desk. Despite this confrontation, she hires him specifically to evaluate adult photographs based on his physiological reactions.

Her responsibilities include assigning tasks to staff. She directs reporter Aki Sawamoto to date Ryohei and document his sexual inadequacies for an exposé article. Later, after Ryohei improves his performance with Aki, Yuki permits him to visit her apartment under the guise of reviewing his work report. Upon discovering him stealing and fondling her underwear from a drawer, she reacts by throwing him out of her apartment window. The story concludes with her realization that he also took her bra during the incident.
