The manga series was adapted into a twelve-episode anime television series by Manglobe. The anime aired in the noitamina timeslot on FujiTV. The anime has been licensed by Funimation as a part of their deal with Fuji TV that allows them to simulcast series from the noitaminA block. This agreement allows Funimation to show the anime on their website at the same time it airs in Japan, and then at later times on the same day on both Hulu and YouTube. NIS America has licensed the series for DVD release in 2012. Rōnin Akitsu Masanosuke is a skilled swordsman, but his personality often causes him to be let go from his job. One day he encounters Yaichi, the leader of a group calling itself "Five Leaves" and takes a job from him as a bodyguard. Though he is worried about their intentions, he feels there is something more to the group and agrees to work with them.
