Path of the Assassin, Volume 5: Battle of One Hundred and Eight Days — Kazuo Koike

It's a battle of ninja vs. ninja, with all the stops pulled out and every trick in the book. Well, almost every trick. Our protagonist/ninja, Hanzo's young ninja wife, Tsukumo, must avenge her father's death at the hands of another shadow warrior, but he's as crafty as they come. This mystical, imaginative faceoff consumes all 300 plus pages of this action-stuffed volume.
