From the publisher:
Forged in heaven, it is called Kusanagi, the Grasscutter--the lost sword of the Gods. This legendary blade could potentially tip the scales of power for the shadowy Conspiracy of Eight in their quest to overthrow the Shogunate and reinstate the Emperor. With the help of a witch and the souls of dead warriors, they plan to recover the lost sword and bring the Shogun down. But when the fates place the Grasscutter in the hands of masterless samurai Usagi Yojimbo, the ronin rabbit becomes the focus of a deadly struggle for possession of the dread blade. And this crisis pales beside the dark possibilities should the sword come to the demonic warrior, Jei! Grasscutter is Stan Sakai's longest and most ambitious Usagi tale to date: a sweeping epic showcasing one of comics' most individual artistic voices at the peak of his creative skills.
