The Kouga Manjidani clan and the Iga Tsubagakure clan have been sworn enemies for centuries, with only the Hanzo Hattori truce maintaining a tenuous peace between the two ninja clans. But years later, when former shogun Ieyasu Tokugawa faces a succession dispute to determine which of his two grandsons shall become the next shogun, he decides to settle the matter through a proxy war. Selected to represent respective candidates, the Kouga and Iga clans send ten of their best fighters into a deadly battle, with the winning party deciding the rightful successor. Thus, the truce is cancelled and the ruthless bloodshed begins.

But not all approve the truce’s end. Gennosuke of Kouga and Oboro of Iga, both heirs to their respective clans, were to be married in hopes of ensuring lasting peace. However, unlike typical arranged marriages, they were already deeply in love. Whilst the rest are preparing for war, Gennosuke questions his loyalties while Oboro refuses to fight.

With a unique art style Basilisk: Kouga Ninpouchou is a compelling tale of feud and violence. Will the two clans be consumed by hatred or will love change their destinies?
