Cassis was jealous of his best friend Sho Bubu, for having the attention of Melo interest, locked up in a ring and did the same with Melo to take his place as Governor.
The custody of Cassis is not really an obstacle for our team of heroes. Their fighting skills allow them to defeat their enemies while they still have the advantage of numbers. But Cassis still had an asset in his sleeve, he has a kind of giant robot whose armor resists even the powerful laser Yugo.
But Cassis lacks delicacy in the handling of her robot. The brutality of his maneuvers eventually broke an access hatch located under the robot. Amalia then uses her creepers to tie the legs of the robot and make it fall, which allows Cléophée and Evangelyne to shoot two arrows through the opening. The damage caused by the arrows inside the machine make it explode.
Cassis is transformed into a ghost and locked in a buffer, an object reflecting his administrative obsession. Melo takes over his position as governor and can finally marry Sho Bubu. As for Yugo and his friends, they can finally go back to sea.
