This page covers the manga. For the anime, see Yu-Gi-Oh! GX.Judai Yuki is an ordinary student in Duel Academy, a school where aspiring duelists learn the secrets of Duel Monsters. Although he's a member of Osiris Red, the dorm lowest in the hierarchy, where students fear expulsion due to their low grades, Judai has a grand dream: to become the King of Duelists.Published in Shueisha's V-Jump in Japan and Shonen Jump in the US, the manga is based on the anime that came before it. Although the main cast and setting remain largely the same, their development in the manga is quite different, as it covers none of the arcs the anime did. The manga also introduces a completely different set of antagonists and villains, following its own continuity.The first two volumes of the manga cover everyday activities and spars within Duel Academy, exploring the relationships between cards that house spirits and their masters. However, as the series progresses, a darker presence seeking vengeance slowly reveals itself and attempts to infiltrate the school to obtain the spirits.The manga is written by Naoyuki Kageyama and supervised by Kazuki Takahashi.
Manjoume often suffers from The Worf Effect in the anime. No such thing happens here. He even manages to defeat Judai in the finals of an official tournament.
Sho is a better duelist from the outset in this continuity, such as losing to Ryuga only because he cheated and actually putting Judai on the ropes during their duel. His brother doesn't lose faith in him because of a bad play, but because he threw a game to spare his opponent's feelings.
Aerith and Bob: An odd case in the translated version of the manga. All characters that originated in the anime version have their dub names (the Tenjonin siblings, Asuka and Fubuki, are Alexis and Atticus Rhodes, respectively), which not only is jarring with the presence of American duelists, but manga-exclusive characters (Ryuga, Seika Kohinata and Koyo and Midori Hibiki) keep their names.
Beauty Contest: The Miss Academia contest, where a poll to determine the prettiest girl in Duel Academy is held. When Asuka and Seika Kohinata tie for first place, Asuka decides to duel Judai for his vote. She doesn't actually care to win the pageant, however.
Dub Name Change: The English version keeps the dub names, but averts this in the case of new characters.
Dude, Where's My Respect?: Judai places second in a school wide Duel Academy tournament (in which only the top eight even advance to the finals), but Chronos treats him with the same disdain as always, due to a combination of resentment over losing to him earlier, and him being in Osiris Red.
Eleventh Hour Superpower: During the final turn of the Duel with Tragoedia, Judai summons Ma'at herself to end it by fusing Winged Kuriboh with Light and Darkness Dragon.
Executive Meddling: Both the anime and the manga had the tail end of the series rushed due to the execs wanting to push out the newer YGO series (Yu-Gi-Oh 5D's and ZEXAL respectively).
Expy: Tragoedia has almost identical background and motivations with Dark Bakura.
How We Got Here: The eighth chapter of the manga starts with Sho and Judai dueling against each other. It's revealed to the readers Sho will be expelled from Duel Academia if he loses and Judai will lose his cards if he loses. Then it's revealed how it happened; Sho got a 0 on a test, and was told that he had to duel Judai to stay, with Judai's condition largely being put in to keep him from throwing the duel.
An Ice Person: Asuka's deck is full of monsters themed around hail, snow and ice.
Instant Awesome, Just Add Dragons: Manjoume's whole Deck. Special mention goes to Light and Darkness Dragon, the only spirit card in the manga besides Kuriboh and dangerous enough to scare the Big Bad.
Not-So-Innocent Whistle: Judai does this when suggesting that Asuka and Misawa should exchange numbers, saving Misawa the embarassment of asking her himself.
Mythology Gag: The final chapter of the manga contains many references to the anime continuity. Johan appears in his possessed outfit, Kaiser in his Hell Kaiser garb, Manjoume in his "Black Thunder" coat, and Judai in his Season 4 look. None of these had previously been shown in the manga.
Chronos forces Judai to duel Sho. If he wins, Sho will be expelled, and if he loses, his deck will be confiscated. He decides to win, and it turns out that Sho's 0 on the last test, the reason he was in trouble, was not his final grade.
Midori is given the choice between defeating Reggie in a duel, and trying to find out what she knows about Shadow Games (her brother is the victim of one). She goes for the latter after noticing that Reggie will duel Judai next, but is defeated and finds out that Reggie knew nothing.
School Uniforms are the New Black: Misawa and Asuka make fun of Judai wearing his school uniform to his duel with the awakened Koyo after graduating, but Sho thinks this suits him.
Self-Imposed Challenge: Manjoume, as a result of the above motivation, buries his Light and Darkness Dragon card to prove he can win alone, and vows to leave the academy if he loses even once. However, his loss against Judai brings on Character Development, and he resolves to fight alongside Light and Darkness Dragon again.
To Be a Master: Judai aspires to duel professionally like his mentor, Koyo Hibiki. The American students are fighting for the chance to go pro.
Tournament Arc: Two. First, there's the academy-wide tournament, then the tournament with the American students.
The Worf Effect: Terra Firma, one of Jaden's strongest cards, frequently gets disabled with traps or spells, or destroyed. Relatively few of his duels are won with the help of that card.
Worf Had The Flu: The one time Judai defeats world champion Koyo (out of around 70 matches), Koyo was not using his standard deck. Additionally, Midori would have defeated Reggie if Reggie had not manipulated her into holding back for the sake of finding out information to help her brother.
Yin-Yang Bomb: Manjoume's ace card, "Light and Darkness Dragon". It's even in his name!
You Monster!: Manjoume calls Tragoedia this after the latter refers to humans as insects. He states he'd rather be an insect than a monster.
