After Kopu gives Takeshi and Kintaro the device, Doruge turns a man into the Stonefish Demon Agent, Okozeruge. While Okozeruge and a group of Antomen are attacking Takeshi and Kintaro, they transform into Barom 1. After a long fight, Barom 1 finally throws Okozeruge off of a catwalk on a tower, killing the Demon Agent but turning the man back to normal. At the end, Kopu dies from unknown causes in a massive explosion.
