RD is one of the Blessed Dead, and he wants to rebirth. However, he doesn't want to lose any precious memories of his past love and family. As he desperately makes his way towards the River Styx, where he could escape by boat, Cerberus, the multi-headed hound, threatens his already non-existent life.
