Beneath a Crimson Sky

1638. Edo. The scent of cherry blossoms gives way to the stench of blood and ozone as shimmering tears in reality unleash chaos. Roman legionaries march alongside futuristic warriors, and Spanish conquistadors stalk the streets.  Feudal Japan faces not invasion, but temporal anarchy.
Akira, a young samurai, finds his father slain by a weapon out of time—a Roman pilum.  His grief fuels his vengeance, ignited by Kitsune, a fox spirit bound to his soul. Kitsune grants Akira the power to manipulate time, a gift that comes at a terrible price.  He can accelerate his blade, rewind fate, but each use leaves him colder, mirroring the encroaching temporal frost.  Kitsune whispers of the Chronomaestro, a being who orchestrates the rifts, seeking to mend history's flawed branches, regardless of the lives consumed.
Driven by vengeance and a dawning sense of responsibility, Akira joins Hana, a warrior monk whose monastery vanished into a rift, and Kenzo, a wizened onmyōji plagued by visions of Edo’s annihilation.  Their journey takes them through a ravaged landscape, where samurai clash with conquistadors beneath the shadow of Mt. Fuji, and the Shogunate’s desperate grip tightens, fueling dissent.
In a hidden enclave, Akira finds unlikely allies: Sayo, a swordsmith forging blades that cut through time, and Ren, a shamisen player whose melodies soothe the temporal distortions. But trust is a fragile thing in a fractured world, and betrayal lurks in the shadows. Whispers of a “Temporal Savior” surface, prophecies entwined with Akira's destiny. Yet every manipulation of time creates ripples, unforeseen consequences that reshape the future.
Akira discovers the Chronomaestro is not a monster, but a future descendant, driven mad by the devastation of his own time, seeking to prevent it by pruning the past.  Faced with this tragic truth, Akira must choose: rewrite history, or forge a new path?  In the heart of a swirling temporal vortex, he confronts the Chronomaestro, not with steel, but with the strength of his will, the weight of Edo's fate resting on his young shoulders.  His choice will not erase the rifts, but transform them, weaving them into the fabric of Edo, creating a vibrant tapestry of time where samurai, legionaries, and warriors from futures unknown coexist beneath a crimson sky, forever changed.
