Kouga and a young Makai Priest named Reo Fud? are assigned to deliver a new Makai tool, the G?ry? named Colt to the Western district Makai Priest. While en route to their destination, the two arrive at the lair of the Horror Melgis. Reo asks the Makai Knight to let him and his G?ry? Colt handle the monster. Though wounded, Reo manages to destroy the monster, but Kouga's car is damaged in the process. Later, as Reo tends to his wounds, he and Kouga proceed to talk about whethre Makai Priests should become more active in dealing with Horrors. The next day, the case holding Colt is no where to be seen. While searching for the case, Colt appears from no where to attack Kouga. Colt rejects Reo's orders as it combines with a motorcycle and drives off, much to the young Makai Priest's shock. It is revealed that Reo's blood dripped into Colt and caused it to develop Horror-like instincts which make it a threat. Though Reo is certain Kouga intends to destroy the G?ry?, Kouga shows heart and says he wishes to salvage the weapon. As Kouga races after Colt, he guides it towards Reo, who is able to seal Colt's Horror impulses for the time they need to force a confrontation. Reo manages to create another seal to form a district-wide barrier of sunlight (even though it has already turned night) to keep Colt from escaping and reaching its full power. But when even Garo cannot stop the berserk G?ry? on G?ten, Reo covers himself in self-destruct talismans with the intent of using a suicide attack to destroy Colt. However, Garo manages to get between the two and stabs Colt, exorcizing the Horror influence from the G?ry?. After Kouga tells Reo to trust him in the future, they receive a visit from Rei Suzumura, the western Makai Knight, who reveals to Kouga (and a shocked Reo) that he has also been marked with the Seal of Destruction.
