K: Missing Kings

It's been a year since the disappearance of Shiro, the Silver King; Kurou Yatogami and Neko have been diligent in their search, but to no end. Their investigation leads to a run-in with members of the now disbanded Red Clan HOMRA—Rikio Kamamoto and Anna Kushina—being pursued by the Green Clan, who desire Anna's powers for their own ends. Now, the members of Scepter 4 are called upon alongside Kurou and Neko in order to rescue Anna, the mascot, and only female member of the ruined Red Clan, from the enemy's clutches and hopefully find Shiro using the young girl's powers. Amidst crisis, the group is forced into a power struggle when the Green Clan threatens to overtake the Gold King's domain.
