Instead of dying with the rest of his friends, Yūichirō's best friend Mikaela was transformed into a vampire by Krul Tepes, the queen of the vampires and now works as her aide. Meanwhile, Yūichirō finally begins his training to become a member of the Moon Demon Company.

When the Shinoa squad arrives late, they realize just how serious this mission is for Guren. Knowing this is an impossible mission where many will die, Guren puts his emotions aside and orders his men to not necessarily survive, but to win.
