Aiko, a 26-year-old AB blood type, works as an editorial designer while pursuing a hobby of writing romance novels.

Despite the indoor image associated with her profession and interests, Aiko possesses excellent athletic abilities. She excels in activities such as bowling and badminton, easily outperforming her friends. At the workplace, she is often seen multitasking, eating while working, and occasionally indulging in naps for over an hour. However, her efficiency in getting tasks done quickly earns her no complaints from colleagues. Aiko, with a wealth of romantic experiences, may not be consciously aware, but she has a knack for making her partners fall deeply in love to the point of obsession. Despite having no intention to do so, this aspect can be tiring at times.

When feeling fatigued, Aiko takes a break with a blend of apricot and orange tea. Any brewing method is acceptable.
