Overview: At Club Lupo, Rei Suzumura is alerted to a Horror sitting nearby as he finds a group of Horrors about to eat a bloodied man that Silva identifies as being called a Blood Dolce. After killing off two of the Horrors as Zero, Rei encounters another in a white suit that overwhelms him with his feathers before telling him not to interfere as he takes the man named Katou with them. With Silva unable to track the mysterious Horror, knowing that Katou is beyond saving yet feels he deserves a better death, Rei asks his Madōgu to report the turn of events to the Western Watchdog. The next day, Rei is attacked by a mysterious girl with a Makai Blade, but their fight is interrupted by an eccentric man. After introducing herself as Yuna, she apologizes to Rei, saying she just wanted to test him, and her Makai Priest partner Kain explains that they have been assigned to work with Rei in going after the Horror he encountered: Ring. Rei does not trust either of them yet decides to hear them out after Yuna reveals Ring's unorthodox intent to create a human/Horror coexistence. As Rei treats Yuna and Kain to Club Lupo, Katou is fed to the Horrors in Ring's community.
