Shinobi: Heart Under Blade (2005)

In the shadowy depths of Japan's Tokugawa era, a blazing drama unfurls between two rival ninja clans — the Manjidani Koga and the Tsubagakure Iga. For centuries, these clans have dwelled in the labyrinthine woods and towering mountains, refining their Shinobi martial arts into fearsome, superhuman skills. However, an imperial decree forbids them from sharing their deadly techniques and forces them into a brittle peace, a peace that will soon be shattered by the machinations of a nefarious advisor, Nankobo Tenkai. Driven by a thirst for absolute power, Tenkai convinces the ruling lord that the clandestine clans pose a grave threat to the region's tranquility. In a poisonous stroke of Machiavellian cunning, he orchestrates a contest designed to annihilate their most formidable warriors. This is no ordinary competition, but a grim duel to the death! Meanwhile, amidst the looming storm of conflict, a tender romance blossoms between two unlikely souls. Oboro, the compassionate granddaughter of the revered Iga clan matriarch Ogen, and Gennosuke, the gallant son of the formidable Koga clan leader Danjo, find themselves entwined in a forbidden love. But when the leaders of their respective clans perish in combat, Oboro and Gennosuke are thrust into positions of power, their love story now a backdrop to the escalating clash of their warrior clans. As the ultimate battle of the Shinobi clans hurtles towards its climax, the star-crossed lovers must navigate a world where love and duty collide, and every step could be their last. Shinobi: Heart Under Blade is a riveting tale of love, honor, and betrayal, set against the breathtaking backdrop of feudal Japan.
