Set in the Victorian age in the fictional city of Anargal, we follow Arthur Artorias, a man stripped of his past, tortured, and forced to escape into isolation. Thought to be dead, he returns eight years later a changed man, disfigured, seeking answers and pursuing revenge.
On Arthur's latest mission, he comes across the term uttered by his victim, "Greater Heaven". Arthur's father said the same thing before he was killed by his attackers on that faithful night. Arthur starts to ponder what if anything does his victim and his late father share in common. And were their fates connected by Arthur's benefactor?
