Nene Yoshitaka, at just 19 years old, made her debut with a one-shot manga in the shoujo genre. After drawing several one-shots, she joined the ranks of serialized creators under the pseudonym "Karegozu" or "Bull Head." Originally a pure and innocent woman, she fell into darkness during Calegos' popularity decline, eventually becoming a hikikomori (social recluse) for seven years after the series was canceled. However, due to passionate requests from fans and editors alike, she begins working on new material once again. As she inhales the scent of men, long-dormant desires erupt within her, leading to vivid fantasies about fulfilling those urges... "It's your smell that has me all worked up," she confesses, finally breaking free from her self-imposed isolation.
