What does humanity fear most? Death, perhaps. But what it should fear is the void.
They say those who've fallen always stare back.
Tetsu is a boy from a forgotten rural village in Sendai, living among garbage, with only his mechanical dog Buff by his side. Day by day, they barely survive-until one fateful encounter changes everything. A Fallen appears and kills the boy. But in a desperate act of loyalty, Buff sacrifices himself and gives Tetsu his core, turning him into an Errant. The result? A massacre that wipes the village from the map.
Tetsu is soon captured by a mysterious government-backed organization.
But the real question remains:
What is a Fallen? What is an Errant?
Simple-
They are those who came back from the void...
to stare back at you.
