When the ruthless Marshal Saints raid his village, murder his wife, and kidnap his young son Ethan, Ren Arashi’s peaceful life is instantly destroyed.
Driven by an unyielding will to survive and rescue his boy, Ren scales the forbidden peaks to undergo brutal training under the ancient Karasu-tengu. Struck by a thousand bolts of lightning, he returns to the mortal realm utterly transformed into a Guardian.
Tracing the stolen children to the Black Crane Monastery, Ren uncovers a terrifying cosmic conspiracy. Dark powers are harvesting rare bloodlines to unlock sealed gates between realms, and Ethan is trapped somewhere beyond them.
To save his son, Ren must cut through corrupted masters, ancient blood rituals, and multi-dimensional threats.
