Nayuta Tenkawa

Nayuta Tenkawa is a mysterious girl being cared for by Mihari Oyama's faculty advisor Chitose Azuma. A loner with an unknown background and no social life who wishes to be Chitose's research assistant, she is enrolled by Chitose at Yotsuba University Affiliated Junior High School during Mahiro's second year in order to monitor Mihari's experiment without her knowledge. She befriends Mahiro after revealing that she knows the truth about her, and quickly joins Mahiro's group of friends. Nayuta is a young second-year middle school girl. She has long shoulder-length blue-colored hair with prominent bangs and green eyes. She also wears a small gold bear-shaped hairclip on the right side of her hair. In more casual situations, she wears a beanie and places the hairpin on it instead of her hair. She is also notably not very well developed as a female, but is further along than Momiji and Asahi, with her bust being only slightly larger than theirs. Nayuta is a smart, but shy girl who begins to come out of her shell after joining Mahiro's group of friends. Having spent so much time alone reading in the university library, Nayuta possesses a lot of knowledge for a girl her age. It is unknown how well this translates to her schoolwork, but it can be assumed that this has helped her greatly. It is entirely possible that she is a prodigy much like Mihari, which would explain her interest in being Chitose's research assistant. She was subsequently seen to be overjoyed when given the opportunity to help Chitose with her research.
