They move on to the Graduation ceremony, and Sheppard calls the second-year representative, [[Tyranno Hassleberry|Hassleberry]] forward to give a farewell speech. He too, begins weeping, and has to be escorted out just as Crowler was. Alexis has been chosen to be the representative for the third-years, so Sheppard calls her forward to give her own speech. As she speaks, a montage of flashbacks is shown, with events from all four seasons being played. Alexis states that time moves too fast, and it seems like they only first arrived at the Academy recently. She states no one will ever forget the friends they've made at the Academy, no matter how far away they may become. The ceremony begins, and the students receive their diplomas, before heading to the graduation party at the [[Obelisk Blue]] dorm. [[Axel Brodie|Axel]] and [[Jesse Anderson|Jesse]] are still present, and they state they'll be leaving to go to their own Graduation graduation ceremonies shortlyon different days. [[Yusuke Fujiwara|Yusuke]] arrives, and apologizes for all the trouble he caused. [[Atticus Rhodes|Atticus]] tells him he's wrong, Duel Academy will accept the growth and mistakes of any student.

Jaden does not attend the party, and instead begins packing his things up in [[Slifer Red]] dorm. The spirit of [[Lyman Banner|Professor Banner]] questions why, and Jaden states his work here is done. He states that he intends to begin traveling, and aid anyone he can with his power to connect humans to Duel Spirits. At the same time, during the party, Alexis, Jesse and Axel have a conversation outside of Obelisk Blue dorm, confident that they will see Jaden again. As Jaden leaves, [[Winged Kuriboh (character)|Winged Kuriboh]] flies off, and he follows him. He's lead the room where Yugi's replica deck is stored. Waiting for him there is Yugi himself, who tells him it's time to begin the true graduation Duel. He says he is going to test Jaden to see if he has become a Duelist worthy of holding [[Winged Kuriboh|the card]] that Yugi gave him three years earlier. He states that Jaden has grown into a reliable adult, but that there is something that Jaden has lost, but not yet realized it, and that thing is extremely important. He instructs Jaden to hold "[[Winged Kuriboh (later anime)|Winged Kuriboh]]" up to the display case, and that it will lead him to the [[Yami Yugi|person]] who can help him recover what he has lost, [[Yami Yugi|somebody]] that Yugi considers even stronger than himself.

[[File:FlyerGX179.jpg|thumb|right|200px|Flyer showing Yugi and his friends, after [[Battle City V2]]. From left to right: [[Téa Gardner|Téa]], [[Yugi Muto|Yugi]], [[Joey Wheeler|Joey]] and [[Tristan Taylor|Tristan]]. At low left corner: [[Seto Kaiba|Kaiba]].]]He does so, and is engulfed in light. He suddenly finds him himself in front of [[Solomon Muto]]'s [[Kame GameStore|game shop]] and finds a flyer on the ground. It appears he's been transported back in time to just after a second version of Battle City tournament ended, as the flyer announces Yugi as the winner. Yugi rushes from the shop, telling his Grandpa that he's off to school, and bumps into Jaden in much the same way that Jaden did to him [[Yu-Gi-Oh! GX - Episode 001|when they first met]]. Yugi does not appear to remember Jaden, and states he doesn't remember giving him "[[Winged Kuriboh]]", but comments it does resemble his own "[[Kuriboh (anime)|Kuriboh]]" as he compares the cards. He states that the spirit of "[[Kuriboh]]" contacted him in a dream the previous night, and told him that he would soon meet someone whom he must Duel. They find a spot to Duel, and Yugi comments that there doesn't appear to be anyone else around, and Jaden notices the clock has stopped. As they shuffle each other's Decks, Yugi states that he senses [[Yubel (character)|something]] in Jaden, and believes that they are similar to one another. As they move to their Dueling positions, Yubel comments that she's impressed that Yugi could sense her, and also says that his Deck will be a problem, with Jaden replying that he could sense powerful energy coming from it and that it must be the [[Egyptian God]]s.

Jaden Summons "[[Elemental HERO Hero Flame Wingman(later anime)|Elemental Hero Flame Wingman]]" on his first turn, and Yugi comments he's not seen "[[Elemental HERO|Elemental Hero]]s" before. Yugi Summons "[[Mystical Elf (anime)|Mystical Elf]]" and [[Tribute]]s it using "[[Magical Dimension (later anime)|Magical Dimension]]" to destroy "Flame Wingman" and [[Special Summon]] "[[Dark Magician (anime)|Dark Magician]]". Jaden uses "[[A Hero Emerges (anime)|A Hero Emerges]]" to Summon "[[Elemental HERO Hero Neos(later anime)|Elemental Hero Neos]]". Jaden states that "Neos" is his ace card, just as "Dark Magician" is for Yugi. He claims that the Duel has yet to really begin.
