Konosuke and his companions have caught up to Dosuke near the site of one of the Sessho-seki that Tsuki has just unsealed. In the presence of its evil miasma, gifts increase in power. Konosuke will need the boost as he confronts Dosuke and has a chance to free Tsuki. But taking down Dosuke and his sister, Katsu, will be no easy task. Katsu herself is possessed by a similar ancient and demonic entity as Haretake. To defeat it, Konosuke must wield his gift, now manifested as the icon of that which he has always sought to hold...a katana!
