The Crumbling Tower of Evil!! (Kuzureyuku Jyaaku no Tou!!- 崩れゆく邪悪の塔!!)

An attemp to murder Prince Heinell was disrupted by Kazarin, but she was shot and died in Heinell's arms. The trio Gou brothers finally met their father. The Boazanian legend said that The Protector God of Boazan, Godor, will defend Boazan if there's a Boazanian that loves Boazan so much that he is willing to sacrifice himself by jumping into the flame on the right hand of the statue of Godor. The desperate Prince Heinell then was moved to sacrifice himself into Godor's flame but it turned out that Godor statue was actually a robot. Fight between Voltes and Godor was unavoidable. Duel between Kenichi and Heinell soon followed. There, the secret of Heinell's origin was revealed by a dagger. Dr. Gou realized Heinell was his son from Rosalia, wis wife. Emperor Zu Zanbajir went mad and was killed by Heinell. An explosion separated Heinell from his long lost family. The battle was over and Voltes flew back to Earth.
