Mugen no Juunin

Strange organisms within Manji's body heal wounds that should kill him, but immortality has not freed the swordsman from his guilt. Rin Asano seeks him out after the Itto-ryu destroy her family, asking him to guard her on a journey of revenge.

Their path brings them against fighters whose convictions are as dangerous as their blades. Manji's experience and Rin's determination cannot make every moral choice simple, and deciding who deserves death proves harder than delivering it. Their uneasy partnership tests the meanings of atonement and justice in a world where each act of violence leaves another grievance behind.
