Naga's troops have finally infiltrated Wardington after two defeats. Alice discovers that Tricloid's sister Rabeeder is invading the town. Little does she know the one she trained, Christopher, will also get involved in the battle. Dan is informed that Hairadee, Centorrior, and Druman are also approaching the city following Tayghen and Tricloid's defeat. When it appears these two are being overpowered, Klaus arrives. The three soon realize all that Rabeeder is doing is being controlled by her worry for her sister Tricloid. Alice starts doubting herself but Christopher helps her. Hydranoid defeats Rabeeder and is reunited with Tricloid as both of them return to Vestroia.
