Kluke has woken up and is good now. Shu and the others continue their journey to the book of origins. Now Shu and the others are in logic city in their journey.

Cynthia has grown jealous of Bouquet's beauty. This causes her to seek out and eliminate her. A fight on the narrow path causes everyone to fall into Death Valley. Bouquet brings out her Hippopotamus shadow to turn into a ball...which ends up scattering everyone. As Shu and Co. evade the experimented creatures there, Cynthia learns from Andropov that the fog there has softened the cliff sides to the point where it is impossible to climb. As Andropov tries to find a way out for Cynthia, Bouquet and Hippopotamus secretly follow her to find a way out with Bouquet leaving a trail of her clothes for the others to follow. When her cover ends up blown near the exit of Death Valley, Cynthia attacks. Things weren't looking good for Bouquet and Hippopotamus. When Shu and Co. arrive, Cynthia retreats.

After Gilliam, Todd, Bishop, and Cynthia's defeat, General Logi sends Andropov, Lemaire, and Schneider to take on Shu and Co. Zola faces off against Lemaire while Jiro and Marumaro fight Andropov and Schneider. Lemaire has Deucalion use its bazooka attack to create a crater where Lemaire will have the advantage in. Shu faces off against General Logi. With Lemaire defeated by Zola, Kluke goes to help Shu while Bouquet infiltrates Logi's ship.

Mikhail leaves thereafter, before warning Shu that the fate of the world lies in the choices he and his friends make. Back with Logi's duel with the mysterious woman, she states that he was not qualified and in a flash sets Logi and Albarose ablaze. Watching from a distance were two tightly cloaked characters. Feeling the need to gather the previous partners being shadow users, Shu takes Bouquet and Noi to Marumaro's village to awaken Marumaro's shadow Saber Tiger. But starting out on a wrong foot sets Noi and Marumaro at each other's throats. To settle their differences Shu has Marumaro and Noi compete in different sporting events like arm wrestling, racing, and other events. When it comes to a card game, Noi wins and uses his Tousen Kyuden to awaken Saber Tiger. The Investiture Beings are in their meeting and have elected Shu as the World's Representative. Mikhail leaves to watch over Shu's progress.

Arriving in a local town, Shu recalls about his attempts to Jiro and Kluke to help him. This causes Marumaro to become concern and Bouquet to feel neglected. Marumaro ends up encountering dancing sisters Donna and Reina. When Marumaro brings them to Shu to cheer him up, the sisters end up dancing with Shu and Noi until Bouquet arrives getting into an argument with Shu. The sisters break from Noi and end up sucking the life out of Shu and Bouquet. Donna and Reina then perform while sucking the life out of some of the townspeople. Marumaro ends up deciding to correct this problem and obtaining Noi's help. Donna and Reina recall when they used to be down and out until Mikhail arrived and gave them Dragon Scales to make them more beautiful. This also caused them to absorb the energy of jealous people. When Donna and Reina leave, Marumaro and Noi emerge from their hiding spots as Noi tells Marumaro that Donna and Reina have the crests of the Dragon Scale on their necks. Marumaro and Noi end up disguising themselves as one person so that Marumaro can use his shadow power to deactivate the Dragon Scales starting with Reina. It doesn't go well when their disguise eventually fails. Marumaro ends up enticed by their beauty until Noi ends up not showing off his jealousy. Donna and Reina end up attempting to entice Noi with their beauty making Marumaro jealous. When Donna and Reina end up trying to absorb Marumaro's jealousy energy, Noi ends up biting Reina. Using Saber Tiger, Marumaro ends up driving the Dragon Scales out of Donna and Reina. Once the Dragon Scales were destroyed, those that they have drained energy from were restored. As Shu starts to regain his energy, he finds out that the name of the girl that has been appearing in his dreams is Primella. He ends up waking up alongside Bouquet. With Donna and Reina still unconscious with Noi stating that they won't remember a thing, Shu, Bouquet, Marumaro, and Noi take their leave. Shu finds out that Marumaro had been worried about him and Bouquet. Shu and Bouquet then end up in another argument revolving around what happened between him and Donna and Reina.

While traveling through the desert, Shu, Bouquet, Marumaro, and Noi come across a ghost town after a mirage incident. When Shu, Marumaro, and Noi find a girl they are attracted to, they get into a fight where Bouquet had to use Hippopotamus' shape-shifting ability to break it up. When Bouquet suddenly falls ill, Shu, Jiro, and Marumaro evade the ghost town's ghosts until they see a flying spider-like creature. They go after it on the back of Saber Tiger. When the giant spider causes a rockslide that brings to life rock monsters, Shu unleashes Blue Dragon who alongside Saber Tiger destroys the rock monsters. When Saber Tiger impales its abdomen with his attack, it unleashes a multicolored water that submerges them. While underwater, Shu notices a green plant and they head toward it while evading giant killer fish. They managed to make a hasty retreat to the surface. As Shu and Marumaro dive back in, Noi turns into his black dragon form and joins them. As Shu and Marumaro hold off the giant killer fish, Noi discovers that the green plant is alive. Blue Dragon manages to yank it out of the ground draining the water. They then end up back at where the scene of their mirage occurred in which it was all a dream.

Shu, Bouquet, Marumaro, and Noi help two female bakers prepare a cake display for a town event to earn some money. But there are delays in the kitchen, and Noi and Bouquet has to stall the crowd until they are done. With help from Shu, they complete the cake display and use Saber Tiger to transport it there. When Blue Dragon bursts out the cake scaring the kids, Bouquet improvises by having Hippopotamus dress up as a superhero called Hipopotaman to fight Blue Dragon. Marumaro has Saber Tiger join the act to help Hipopotaman fight Blue Dragon. This only agitates Blue Dragon in the end who makes sure the party "ends with a bang".
