Following the suicide of his sister, Satsuki Kakeru had lost interest with his own life. He might have never freed himself from the grief if not for his childhood friend, Minase Yuka. One night while both of them were out on a walk, the sky suddenly turns blood red, the moon pitch black. Even more strange, the people around them have disappeared, and hellish creatures begin to roam the streets. After a brief period of hiding, everything returned to normal. Unsure of what had happened, the two boys dismiss the event as nothing but a dream.
Much to their dismay, the Red Night occurs again. However, this time, Kakeru and Yuka meet several people who are also affected by this strange phenomenon: Kusakabe Misuzu, a red-haired onmyouji swordswoman; Tachibana Kukuri, a peculiar mute girl who strangely resembles Kakeru’s deceased sister; Hirohara Yukiko, a lively young girl who takes on the personality of a cold killer when her glasses are removed; and Tajima Takahisa, a young pyrokineticist with a heated attitude to boot.
Aside from the fearsome monsters, six shadows who call themselves the Black Knights desire to kill Kakeru and his companions. With nothing but themselves, Kakeru and his newfound friends must now work together in order to survive and end the Red Night.
