As Rei is forced into a physical and psychological battle with Glum before defeated by her Beast Glum form and seemingly killed off, Kouga arrives to the ritual chamber as Barago holds him off. Karou comes to by then, possessed by Messiah as Barago is devoured by the Horror as she then uses Karou to begin the summoning process while Glum holds Kouga off.

With Rei holding Glum off, Kouga enters through the portal to where Kaoru's conscious is before entering the realm of the Horrors to face the titantic Messiah as she pint-pointed Kaoru's body to enter the land of the living.
