Vincent and Kyu arrive in a magazine's Halloween special. Frightened by the ghastly atmosphere, Vincent wants to leave immediately, but Kyu (who doesn't know the real world) thinks vampires and other monsters are normal. Not only does she not want to leave, but she also refuses to look for the rift as long as she hasn't helped a poor vampire find his lost teeth. Vincent will be forced to help her if he wants to leave these terrifying pictures as soon as possible.

Vincent and Kyu arrive in a magazine where people act really strange. This wouldn't be a real problem if our heroes weren't stuck here! Kyu is no longer able to see the rift that would allow them to leave. A wise old woman explains to them that their arrival in this once peaceful and harmonious world created the disorder. They will have to fight the paper dragon and put everything back to order in this universe if Kyu wants to recover her powers and help them leave. A formidable challenge for shocked Vincent, a boy who has never been able to keep his own room straight!

Vincent and Kyu find themselves in a history magazine. Confronted with a King who thinks the Earth is flat, they have to prove our planet is round so they can save Galileo from being executed. Problem: the Earth really is flat, since they are in a magazine! Vincent tries to prove to the Flats that the Earth is, not only round, but also in three dimensions. He succeeds thanks to a cutout model, to the great astonishment of all Flats present...

Vincent and Kyu find themselves in a "kids" news magazine. But when they move from one page to the next (as they always do), a Flat journalist surprises them and tells the whole magazine of their presence. As a result, all the Flats start following Vincent and Kyu, raising the risk of following them through the rift into the real world. Vincent refuses to have the Flats leave the magazine world, leading Kyu to wonder why he's taking her along... Our heroes nevertheless manage to lead all the Flats to their proper pages and convince them to stay where they are...

Vincent and Kyu obviously wind up in a game magazine. They discover two old chess players in the middle of a game that seems to have already lasted a lifetime. Unfortunately, one of the players is sitting on the rift, thus blocking the exit. Quickly realizing it will be impossible to break the player's concentration and move him, our two friends travel the length and breadth of the magazine searching for a solution to end the chess game.

The kids enter the only world where Vincent of visiting: a video game magazine! What a godsend for Vincent to finally dive into his favorite games "for real"! He hopes to express his passion for his favorite pastime to Kyu, but what slowly shows through is that, in the real world, Vincent spends his time hiding in virtual worlds that are as narrow-minded and stupid as any Flat world... A major humility lesson for Vincent, all the more so since it is much harder for him to succeed "on the playing field" than behind a joystick...while even a novice like Kyu can manage to get out of tight spots!

Vincent and Kyu appear in a wedding magazine. They meet a young bride-to-be in a state of despair because she has lost their wedding bands right before the wedding. Moved by the situation, Kyu decides to help her save her wedding... Though at first reticent, Vincent winds up being convinced to do the same. And they set off through the magazine looking for new wedding bands! An adventure that will transform Kyu's super-romantic vision of marriage...

Vincent, accidentally scanned by Kyu, finds himself locked inside a picture of a computer. While Kyu desperately searches for help among the "Flat" technicians in the magazine, Vincent decides to explore the photos of the hard drive's interior and meets Elodie, a young flat who is a hard drive prisoner. Elodie and Vincent are suddenly attacked by computer viruses that threaten to contaminate not only the magazine, but also other worlds if they reach the "Rift". Will Kyu manage to arrive in time to "print" Vincent and Elodie before they (and the "Rift") are irreversibly affected by the computer viruses???

Our friends enter a magazine dedicated to nothing but fashion! Kyu is thrilled to death, while Vincent doesn't understand the interest of all these ridiculous clothes. He will change his mind – however – when he meets the magnificent model, Elena, to Kyu's great displeasure. Jealous, she starts to wonder if staying in this magazine is a good idea. To crown it all off, a great fashion designer will banish the little fashion princess and choose "unhip" Vincent as his star model...

Vincent and Kyu arrive in a magazine dedicated to music. They land on a musical score and mix up all the notes. Unfortunately, it's the unfinished score of Beethoven's 5th symphony. The composer is crushed because he can't remember the first note and can't write another symphony in time before playing for the Emperor... Vincent, who has vague piano skills, tries to remember the tune, but in vain. Our heroes decide to look for the score in the magazine. They end up finding the tune in question among...the ring tones on Kyu's cell phone! As they go through the rift, Vincent decides to take up piano classes again...

Vincent and Kyu find themselves by an Olympic-sized pool in a swimming magazine. Taking up Kyu's challenge, Vincent tries to dive off of the thirty-meter platform. But it's less the fall than landing in the water that bothers Vincent. In fact, the pool's chlorinated water doesn't take long to cause some strange reactions on Vincent...

Vincent and Kyu arrive in a magazine's Christmas special. Kyu is amazed and Vincent explains the Christmas tradition to her. He does it so well that Kyu starts to believe that the Santa Claus they met is the real one. In order not to disappoint her too much, Vincent has to explain that he's only a legend. But he can't do it. And in the end, he's rather happy when the appearance of the "real" Santa Claus proves him wrong.

Vincent and Kyu enter a magazine about the paranormal. Taken to be extraterrestrials by a group of visionaries, they are forced to run away, chased by the "men in black." Vincent notices that he's a sort of "visitor from another world" for Kyu, which seems absurd because he doesn't believe in the supernatural. However, in a magazine about the paranormal, everything becomes real: the Yeti, ghosts, and extraterrestrials. Vincent is obliged to question all his beliefs in order to escape the creatures chasing after him...
