After donning their Soul Metal Armor, Garo and Zero have an epic battle with Jabi watching as the two combatants are forced out of their armor. However, before Rei can kill a weakened Kouga, Jabi intervenes and spirits him off to where Kaoru is. After Jabi tells her that Kouga was actually trying to find a way to save her life, a confused Kaoru runs off before Gonza finds her and brings her to the cabin where Kouga spent his childhood. As Kaoru regains her faith in him, after his wounds were tended to, Kouga asks Jabi to help him enter the Forest of Glen. After revealing the legend behind the Horror-eating Makai Knight and the true nature of the Eastern Watchdogs, Jabi proceeds to perform the ritual to send the Horror Daggers into the underworld with his help. However, before she could finish telling Kouga something important, Jabi is seemingly killed by Kodama, the Watchdogs' servant. Kouga attempts to fight the stronger Kodama as they fight for the Horror blades. Rei arrives, but is unable to send the Horror Blades to the other side as they turn into a giant Horror. Neither Garo and Zero could harm the titanic Horror as the Horror-eating Makai Knight appears and absorbs the beast before taking his leave.
