In the serene coastal village of Yamikageno, nestled on the shores of Japan in the 1700s, life flowed as peacefully as the adjacent waters. This tranquility was disrupted one foggy morning when a foreign ship, its origins unknown, was found adrift near the village's modest harbor. The local samurai, guardians of Yamikageno's peace and order, boarded the mysterious vessel to investigate, adhering to their duty to protect their people from any potential threat or foreign influence. Unbeknownst to them, this act of courage would unleash an unprecedented horror upon their land. Within the ship's eerie, deserted decks, they encountered not the crew they expected but a virulent form of the undead, beings transformed by a zombie virus that knew no mercy. This fateful encounter marked the beginning of a dark chapter in Yamikageno's history, as the samurai, affected by the virus, brought the contagion ashore, testing the resolve, courage, and unity of its inhabitants like never before.
