Basilisk: Kouga Ninpou Chou

Synopsis

Gennosuke possesses the secret scroll with the names of the dead crossed out and Iga's elaborate deception has come to an end. Oboro, horrified at the deception and death of Okoi, Tenzen holds the Iga back from attacking, as he does not know Gennosuke's abilities, however some men attack, only to be killed by their own swords as a result of Gennosuke's (瞳術 Doujutsu) eye technique. Tenzen allows them to pass and Gennosuke begins to leave, ignoring Oboro. Tenzen sends Chikuma Koshirou to attack Gennosuke, but Oboro intervenes, neutralizing Koshirou's abilities and allowing Gennosuke to wound him with his Doujutsu. The next day, with Koshirou now wounded and blind, and three Iga on the roster dead, Tenzen berates Oboro and demands that she kill Gennosuke, but she refuses and seals her eyes shut with a potion given to her by Ogen.
