Aired on December 21, 2012

Shiro discloses that his current form was inhabited by the White Spirit Fox, who sought his original power but only secured physical possession. The Silver King’s spirit subsequently transferred to the Colorless King’s vessel, resulting in amnesia. He empowers Ashinaka students to flee while coordinating with Seri and Izumo to halt their clan conflict. Shiro recruits Neko as his initial clansman, leveraging her abilities to track the Colorless King. Upon locating her target, Neko collapses, prompting Shiro to depart alone to face the Colorless King directly.
