Kakeru and Yuka are first introduced to the mute Kukuri, who is identical in looks and name to Kakeru's dead sister. Kakeru resumes his sword training with Misuzu at school, soon after which the Red Night falls. During the Red Night, Misuzu is immediately engaged by a black knight, and Yuka and Kakeru are again forced to escape. While running away, they are met by a black knight who blocks their way out of the school grounds. He at first overwhelms Kakeru, but eventually Kakeru's powers awaken in a battle protecting Yuka, and Kakeru manages to fell his black knight opponent.
