When the Hattori truce is lifted, the other Iga are quick to take advantage of Oboro's feelings for Gennosuke, tricking her into inviting him and Udono Jousuke into their compound where the Iga can keep them under surveillance. Although hurt and betrayed by their actions, Oboro remains loyal to her clan and is greatly torn between her duty and her feelings when the truth of the renewed conflict is finally revealed to her. Ultimately, she makes the decision to temporarily seal her eyes shut with a potion given to her by Ogen called the Seven Days of Darkness, knowing that if she saw any of her clansmen attacking Gennosuke, she might be tempted to use her powers against them instead.
