Prologue: The Tyranny Begins

Edo (Tokyo), 64th year of the Meiji era (1931). A storm rages. Lightning splits the sky, illuminating the towering fortress of Edo Castle, a dark monolith against the chaos. The city below is a maze of shadows and fear, its people cowed under the iron rule of an immortal tyrant.

Tokugawa Yoshinobu stands on a raised platform, his eyes glowing with the eerie light of forbidden sorcery. The crowd gathered in the square is silent, the air thick with terror and anticipation. Rain pours down, mingling with the blood already soaking the ground.

Before him kneel the condemned, their faces pale but resolute. These are the dissenters, the ones who dared whisper of freedom. Their fate is a grim spectacle, a warning to all.

Yoshinobu's voice booms, amplified by dark magic. "Behold the fate of those who defy the shogunate!"

A swift motion, and the sword falls. Heads roll. The crowd gasps, the sound lost in the thunder. Blood flows, mingling with the rain, running in crimson rivulets through the cobblestones.

Among the onlookers, a young girl clutches her mother's hand. Aiko Takamori, barely ten, watches as her father's lifeless body crumples to the ground. Her mother's grip is tight, trembling, as they stand witness to the brutal end of their family.

Tears mix with rain on Aiko's face, but her eyes burn with something more than sorrow. Hatred. Vengeance. The image of her father's execution sears into her memory, a wound that will never heal.

An elderly figure steps forward from the crowd, unnoticed amidst the horror. The old onmyoji, sensing the dark power radiating from the shogun, fixes his gaze on the young girl. He sees the potential within her, a spark that could ignite a rebellion.

"Come," he whispers, taking her hand. "There is much to learn."

Years pass. The storm of that night never truly leaves Aiko's mind. Under the old onmyoji's tutelage, she transforms. The girl becomes a warrior, a master of the forbidden arts. Her heart, hardened by loss, beats with a singular purpose: to destroy the shogunate.

Now, as the resistance grows, whispers of the Hono-no-Kage, the Shadows of the Flame, spread through the city. Aiko, now a young woman, stands ready to strike against the tyranny that has gripped her homeland for too long. The shogunate's days are numbered.

And so, the story begins, in the shadowed alleys of Edo, where fear and hope intertwine, and the fate of a nation rests on the edge of a blade.
