Akemi Asakawa

Akemi Asakawa, the second second-year student on the team, is probably the most undedicated out of all the members of her team, as she seems only to care about her boyfriend to the point where she will ditch kendo club over her boyfriend. When she encounters a problem with her boyfriend she will not do her best and will only go on the defense; however, when her boyfriend makes up with her she will immediately start pouring out all of her effort, making her a rather formidable opponent. Apparently none of her teammates save for Kenzaburō have any real concern for her, as they simply let her constant ditchings slide (even if she is ditching from a kendo match).

Kenzaburō, however, is appalled with her habit of constantly ditching kendo just to meet up with her boyfriend and her lack of effort when she is upset. It is revealed in one episode of the anime that Akemi possesses "excellent footwork". (Source: Wikipedia)
