バジリスク ～甲賀忍法帖～

Gennosuke of the Kouga and Oboro of the Iga are betrothed to each other in the hope of ending a feud their clans have kept frozen for centuries. In 1614 the Tokugawa tear that truce up to settle which of Ieyasu's grandsons inherits the shogunate: ten elite ninja from each clan are named and sent to fight to the death. Gennosuke's Manjidani and Oboro's Tsubagakure end up on opposite sides, each heir forced to weigh the person they love against the survival of their own clan.
