S1·E7 Silver Fang

Unable to find information on Rei, Kouga and Gonza speculate that he is from the western district. Kouga made arrangements for the Barankas fruit with Gonza and he heads out for his routine of sealing and entrances used by Horrors; finding that Rei has been doing his job. Kaoru gets a new job as a waitress and Rei stops where she is working for a table full of sweets. Soon after, Rei attempts to kill Kaoru in the back entrance, but Kouga appears to stop him. After having Kaoru be taken back to his manor, Kouga confronts Rei as the two fight their way through Shinjuku's Capital Building where they get a brief interference from a Horror before the two assume their Makai Knight forms. The two fight their way down the Capital Building before they run out of time with Garo the winner to ZERO's dismay.
