Between fantasy and reality, between dreams and wakefulness, between life and death, there exists a world where a small group of people known as the Deathwalkers emerges. Treading the fine line between those realms, they strive to grasp the purpose of this world and unravel why death isn't an ultimate end for them. What is the nature of this place? Where does it reside? How did I come into existence? Who is the one hiding behind all these mysteries?
