Musashi Number 9: Musashi #9 (９番目のムサシ , Kyūbanme no Musashi ) is a Japanese manga series by Miyuki Takahashi about a secret agent working for a mysterious world organization known only as "Ultimate Blue".  #9 is their one of their top agents, a 16-year-old girl who goes by the code name "Musashi #9".  Her aliases include Shinozuka Kou and Shinosaki Kei.  The series starts as a collection of unconnected stories which feature #9 but focus mainly on the more ordinary people she comes into contact with in the course of saving the world.  Gradually, a thread is woven between these one-shot stories, in which Kou strikes up a relationship with the solitary and depressive Shingo Tachibana.  Their lives become irrevocably intertwined in spite of her fairly drastic efforts (for his sake) to leave him behind.  The series is relatively graphic with clear depictions of Musashi's activities, such as fighting and killing off bad guys.
