While heading to rescue Kaoru, Gulm (Ker-ber-rose's merged form) fought Zero while Kouga faced Barago. Messiah by now had taken over Kaoru's body and devoured Barago. She revealed the legend and myth behind the dark knight was a rumor she created to attain enough power to cross into the human world. To save Kaoru, Kouga took her body to the makai realm and Messiah's true body revealed herself. Ultimately, Zero killed Gulm and Garo defeated Messiah. Kouga and Kaoru made it back to the human realm when Kiba returned for a final showdown. Garo defeated Kiba, but at the price of Zaruba.
