While the two of them are investigating a spirit-recombinant ghoul, they accidentally uncover Morgana, a witch-demon girl used as an eternal life vessel by the Walker family. The Walker family mobilizes various forces to hunt them down for the vessel. Jack and Morgana form a blood pact to share their lives and fates. The group braves multiple attempts on their lives and heads to the Bone Wasteland to purify Morgana's grievances and confront the ambitious Eternal Life Society.
