Strike the Blood: Kieta Seisou-hen

Kojou Akatsuki and Yukina Himeragi awaken together in the school gym with an entire day missing from their memories. Their situation is strange enough on its own, but a bloodstained baseball bat, Yukina's vanished spear, and several embarrassing clues make it clear that something far more complicated happened while they were unconscious.

Elsewhere, their friends investigate an eerily deserted vessel connected to Dimitrie Vatler. As both sides chase fragments of the previous day's events, what begins as an awkward mystery escalates into a frantic search for the truth behind the missing holy lance.
