Life in the Shimazu house is back to its usual ridiculous routine, but the new closeness between Shinichiro and Sakuya causes some complications. Shinichiro takes possession of the sword whose True Name he learned earlier, and just in time to help Sakuya and the team face a smoke specter in a subway tunnel. While Sakuya and the other fight to revive a fallen Shinichiro, Suseri battles the Western Mage, but is defeated. Enraged, Sakuya uses her ultimate technique to bring down the Western Mage (who calls herself "Isuca"), but at a terrible cost to herself.
