Ashes of the Rift

In an alternate 1940s Japan where reality itself has been torn open, one man's quest for vengeance becomes humanity's last hope for survival. When Nazi forces emerge from a supernatural rift above Mount Fuji, bringing with them demons and corrupted technology from another timeline, Japan plunges into chaos. The ancient boundaries between worlds begin to collapse, allowing nightmarish creatures to slip through the cracks in reality. Riku Amon, a wandering ronin carrying a mysterious black sword that drinks blood and shadow, finds himself thrust into this conflict when his village is destroyed. Haunted by his family's massacre and driven by a legacy he barely understands, Riku reluctantly accepts his role as the last Guardian of Boundaries—a bloodline tasked with maintaining the separation between worlds. As he journeys toward Kyoto with unexpected allies—a shrine maiden with forbidden knowledge, a child with second sight, and a sister he thought long dead—Riku discovers that his blade, Kurokami, is slowly transforming him. The changes grant him power to face the invaders but threaten his humanity with each use. A dark fantasy epic that blends Japanese mythology with cosmic horror and alternate history, "Ashes of the Rift" explores how far one warrior will go to protect a world that exists at the borders of others.
