is the protagonist. A student of Shuuhou Seiha Private School, ranked Fukushou (second-in-command) of the girl's kendo club and in line for a large inheritance. Naeka presents a unique challenge to Kogarashi; though attractive and extremely busty for her age (and the biggest of the manga. Only in a Kōsuke´s dream her position is in danger by Fubuki), Naeka speaks of walking the "path of the sword" like a warrior mainly to escape from her failed traumatic attempt at love where she accidentally poisoned her crush with a home-cooked bento. She is independent, stubborn, can be a lethal cook, not too bright and coarsely speaks her mind. Naeka suffers both friends and enemies for her figure and manners, and has to tolerate the demanding "service" of Kogarashi -- but through it all, she can still be upbeat and positive. She is depicted as a good swordswoman and will violently attack anyone who offends her with a live blade if necessary, including her own brother.
