Casey repairs his relationship with April and they begin dating. By volume four, he and April are married, raising Shadow as their daughter and trying to have a child of their own. April eventually leaves Casey and Shadow when she learns that she is not human and is a product of the Kirby warp pen. As April comes to terms within herself in Alaska, Casey takes to the nightclubs to drown his sorrows. He meets up with the Foot Clan leader Karai at one of these clubs and, after a few drinks, awakens at Karai's retreat with no memory of the night before, although Karai knows something of what had happened. This plotline was left unresolved as the fourth volume came to an abrupt end.
