Nei is a soft-spoken, gentle girl with a distinctive "windshield-wiper"-like laugh. By virtue of her debut-mates being comparatively odd and high-spirited, she often ends up being the only sane man or straight man when it comes to their antics. However, she herself can be quite silly and just as pon and clumsy as they are at times, Tweeting on the day Ranunculus made their YouTube debut that it was a "spring newbie pon festival".
She has a prickly and somewhat tsundere-esque temperament when it comes to her debut-mates, more than expected from her "soft" appearance - though said debut-mates consider it cute and a positive trait. For example, she once bluntly stated that "Ranunculus is not a teetee group" in contrast to Amagase Muyu having described them as "getting along many times better than you'd expect". Nevertheless, she has shown that she does deeply care for her debut-mates - as well as her pseudo gen-mates in the form of the other VIRTUAL TALENT ACADEMY (VTA) first generation students - even organizing a project to celebrate their second VTA debut anniversary despite her introverted and relatively withdrawn nature.
