Yugo, Amalia, Ruel, and Pinpin and Elely march towards Oropo's tower to rescue Evangelyne and Flopin. When Elely triggers a trap, the group are suspended in a temporal zone where each step ages them. Oropo probes the minds of the group, causing them to face their darkest fears.

The gang arrive at the Iop floor of the tower, which turns out to be protected by a corrupted Goultard, who goes by the name, "Dark Vlad". Percedal decides to fight him on his own and the fight brings back some memories of the moments the two of them shared.

Yugo, Amalia, Elely, and fake Ruel arrive at the Sadida floor wherethey meet the Demi-God of the race, revealing that she doesn't want to fight, but to talk. She discovers the Fake Ruel among their party and captures him. Arpagone tries to convince the real Ruel to join her and Oropo. Evangelyne and Flopin manage to escape their prison but are intercepted by Toxine and Echo. Echo tries to persuade them to come back, but Toxine electrocutes her and chains her up as her hate for Echo trumps everything else. She goes into a sadistic fight against Flopin and Eva and they somehow manage to fight her off but launching her into a Well of Shadows – a representation of her own soul, dark, evil, and chaotic – but she fires an energy bolt as she falls in, striking Eva in the womb and electrocuting her.

Thanks to Toxine, Evangelyne goes into labor while the baby's godly powers activate, causing untold pain as she prepares to give birth with help from Echo, who is able to minimize the pain. The baby, having a demigod's strength, causes the tower to crumble from the shockwaves it emanated during labor. Only Oropo's power is preventing the tower itself from collapsing, but only barely. He sends Adamai to find the cause, finding it to be the son that is coming. He decides to keep them safe from the crumbling debris around them so that he and Echo can have a conversation later. Eva gives birth to a boy, ending the shockwaves and the pain, but the tower is in shambles. Oropo and Adamai set the pieces with those alive gently on the ground, allowing everyone to reunite and for Percedal to meet his new son. Before she could head over, however, Fake Ruel knocks out Amalia and transforms into a fake Amalia, sending the real one to Oropo.

Along with Amalia and sharing a tender kiss, Oropo tells the story of his birth, revealing his true identity and the motivation behind his actions. When Yugo used the Eliatrope Dofus' to help Percedal battle Ogrest, he had inadvertently created a time loop in which a shadow race, the Eliotropes, were created long ago. They were essentially copies of Yugo, but they slowly began to die off, leaving Oropo as the last.

Oropo is about to open the Hyperzaap and use it to destroy the gods. As he reveals his true intentions and the fact that he lied to everyone, with the Sadida Demi-Goddess revealing that it was he who set the world's tragedies into motion, such as Nox finding the Eliacube and Ogrest turning into the demon he was, his brotherhood of demigods start to turn against him. He uses his powers to send Yugo into a coma, where he confronts his demons in the forms of Qilby and Nox, who he had been suffering waking nightmares from since he arrived at the tower.

The Brotherhood of the Tofu and the demigods join forces to stop Oropo from killing the gods in a final battle that will decide the fate of the World of Twelve, and the universe. After a climatic battle, Oropo activates the Hyperzaap. In a last act of self-sacrifice, Echo uses her powers to send Yugo's group and the Demi-Gods though the Hyperzaap, leaving her and Oropo, who still loves her, to die as the Eliacube creates a massive black hole that destroys Oropo's dimension. Yugo and his friends find themselves in Inglorium, the realm of the gods.
