Gennosuke Kouga (甲賀 弦之介 "Kōga Gennosuke") the heir of Kouga Danjou who assumes leadership of the clan following his grandfather's death. An idealist and scholar who believes in looking to the future instead of being dominated by the past, Gennosuke views the pursuit of any grudge to be an ultimately pointless and self-destructive practice. He adheres to his ideals even after learning of the Hattori Truce's absolvement, prompting him to lead the Kouga on an expedition to Sunpu to plead with former Shogun Ieyasu and Hattori Hanzou to reinstate the treaty before any further bloodshed occurs. Yet despite being a man of peace, if pushed into a corner Gennosuke is more than capable of killing anyone who threatens him or his clansmen. In addition to his skill with the sword, Gennosuke wields a power passed down his bloodline called Dojutsu. A hypnosis technique, Dojutsu allows Gennosuke the ability to reverse the homicidal intent of anyone who meets his stare directly effectively causing them to kill themselves instead of him. Because of his power, the Iga level the playing field by temporarily blinding Gennosuke with the same Seven Days of Darkness ointment Oboro used on herself.
