Eryk travels with Herleif Astralia into the Demon Beast Mountain Range-their destination the Morkdypt Ravine. The areas they must traverse to get there are teeming with A-Rank Demon Beasts, creatures no human Spiritualist would dare challenge.
With death around every tree, Eryk and Herleif will have no choice but to rely on their strength and wits to survive, and what they find when they finally reach their destination may be even more than they can handle.
