Age: 32 Measurements: B102 (K-cup) / W61 / H97 (cm) Occupation: TV station announcer (primarily weather) Personality: Brisk and cheerful during broadcasts, but easygoing and a bit airheaded in private.

She majored in meteorology at university and obtained her weather forecaster certification while still a student. She also drew attention for her looks, being selected as a campus beauty queen.

After graduating, she joined a major commercial TV station as an announcer. In her first year, she served as an assistant for a news program and was praised for her calm voice and accurate script reading. However, her outstanding proportions (especially her K-cup bust and hips) became a hot topic within the station, marking her as a "newcomer with both looks and talent." From her second year, she was entrusted with the weather forecast segment, gaining even more support from viewers with her professional meteorological knowledge and friendly smile.

She became a trending topic on social media, with comments like "Listening to Ms. Nijihara makes me look forward to the weather" and "She's so beautiful and healing today." Furthermore, when a weekly magazine capitalized on her popularity by featuring her in a photo spread, it caused a massive stir despite not containing any swimwear, earning her passionate support particularly from male readers.

Currently, she is the main weather caster for the large weekday evening news program "Evening Rainbow." Her style of providing easy-to-understand explanations of weather maps while adding comments that resonate with viewers' daily lives is well-received. Her trademark look—a white top paired with tight pants that highlights her great figure—has made her an "object of admiration" for women as well as men. Within the station, she is called the "Rainbow Goddess of Ratings" and is a role model for junior announcers.

In her private life, she is an indoor person, spending her days off growing houseplants or reading.

She has little experience with men, having only dated two people during her university days. However, because both of them were only after her body, the relationships were short-lived. Though she never shows it, she actually has a strong sex drive. Having experienced various types of play during those short relationships, she has recently found that self-pleasure alone is no longer enough to satisfy her.
