Shinobi: Heart Under Blade

Set immediately after the Japanese Sengoku period, Iga and Kouga, two mercenary clans have been waging a vendetta against each other over hundreds of years. Around 1614, Tokugawa Ieyasu, the ruler of Japan and the founder of the Tokugawa Shogunate, perceives the threat posed by the two clans. Attempting to consolidate his reign, he deliberately stirs up their feud by inviting the clans to choose their five best warriors to fight to the death. Designated as the leaders of the two clans respectively, Kouga Gennosuke (Joe Odagiri) and Oboro (Yukie Nakama), who have secretly married, are unwillingly embroiled in the political plot. Hence, they have to make a difficult decision.

Initially, being peaceful and knowing the preciousness of life, they try their utmost to prevent this meaningless and brutal fight by questioning the shogunate's motives. After the deaths of all their comrades, however, they gradually accept their fate. In the last fight, Kouga Gennosuke chooses not to defend himself and allows his lover Oboro to kill him, thus letting the clan of Iga "win". Meanwhile, Ieyasu sends his armies to exterminate the ninja villages. To accomplish Gennosuke's hope of saving them, Oboro implores Tokugawa Ieyasu not to destroy the villages and, as a show of her sincerity, blinds herself, thereby destroying her most powerful weapons, her eyes (which possess a deadly technique called "Piercing Eyes" (破幻之瞳, "Hagen no Dō" lit. "the pupil of annihilation"). Moved profoundly by Oboro, Ieyasu withdraws his armies and issues an injunction to protect the ninja villages. For generations hence, the villages live peacefully.
