Nana Otohime (乙姫 菜々, Otohime Nana) is a female character from the Japanese manga and anime series Kochikame by Osamu Akimoto. She is a motorbike police officer within the Transport Division of the Katsushika Police HQ. She also has a side job as popular shōjo manga author Miko Aino (愛野神女 Aino Miko).
Unlike the majority of other characters in Kochikame who possess natural hair colours, Nana has a shade of blue-green/aquamarine coloured hair. It is kept as a short bob with bangs consisting of multiple locks of hair at equal length which cover her (still-visible) eyebrows. She also has blue eyes in the manga series, but what are possibly olive-green or hazel-coloured eyes in the anime.
Nana is feminine and compassionate in character, and to an extent quite sensitive. But she is able to better take care of her emotions, compared to her boyfriend Honda, who seems to become easily distressed emotionally.
Other than biking, she shows a great love for drawing anime, which is evident from the fact that she is a manga author who works under her own pen name.
