It's another new day in Lumiose City, but things have changed ever since the first Cardfight. As everyone has their breakfast, the newscasters explain a new craze that's been going on. That said craze, just so happens to be Vanguard. Ever since the filming of the game between Ash and Kai, everyone around the world wanted to get in on the new craze. "This is spreading like wildfire," Serena pointing out the news, "I just can't believe that it would cause this much craziness." However, that wouldn't be all that the news would share. As the news also reports, more new people have been coming to the Kalos Region, all with the same interests and love of Vanguard. The Cardfighters each look at each other with concern, as they think that these people could be friends of theirs. "Kai?," Ash calling out to the leader of the fighters, "Could they be, as you say, "mates" of Aichi too?" He nods just as the other fighters nod. "We should get out there, everyone," Emi announcing to everyone, "The more mates that we rescue, the closer we will get to Aichi!" The entirety of the trainers, Cardfighters, and all of the Pokémon, all cheer in agreement and joy.
After everyone exits the lab, there are stopped by a promotion at the closest billboard at one Prism Tower square. Sycamore said that the Vanguard news has been spreading around like wildfire, at least, that's what his assistants and fellow adults have said. The said news, is for a very special Vanguard tournament. A mysterious group known as the Quatre Knights has challenged this region and the entire world to the first-ever "Worlds Collide Cardfight Vanguard Grand Tournament!". The format for the tournament is an intriguing one, but also an inviting one. The format will consist of 4 Levels, each one bringing new mechanics and strategies to the game. As the world would learn more about the game, the more their own strength will grow. At each tournament, created teams will compete to battle the "Gate Keepers" based on the level that they are at. Beginners start at Level 1 and use the selected cards provided in the new Vanguard app, to defeat the other teams. If the teams have been defeated, the winners will reach the Gate Keepers' stronghold. Once at the stronghold, they'll prove their worth on that level, by facing the Gate Keepers on that Level. Defeating them will give them access to the next level. That's also not to mention that they'll have another level of cards to pick from. Each level will increase in difficulty, the cards will be tougher, and the Gatekeepers will be stronger. In the end, if a team gets through all 4 levels of competition, they'll face the Quatre Knights. Should they be defeated, they'll face a mysterious fighter, which when looking at the photo in the promotion, Kai notices it to be a familiar friend. "That silhouette... there's no mistaking it, that has to be Aichi Sendou," Kai says to the group, who are also looking at the poster. While the Cardfighters huddled up with each other, the other people, the trainers are confused. The fighters then turned around to face the trainers. Shin was the first to speak to the others. "You know, back in our world, I was the coach of our Team, Team Q4. It was Aichi, along with Misaki, Kamui, and Kai." The trainers look at each other and realize that they're in the presence of champions in their own right. Bonnie is a little worried, "Will you still be friends with us? I'm worried that we might separate..." Misaki and Emi step forward and proceed to kneel to her level. "Don't worry, Bonnie," Misaki speaking to the youngest of the girls, "We will stick together, no matter what comes at us." Misaki even shows her a deck and Emi shows a deck, but she has her deck loaded onto her gauntlet. "As soon as we decide our clans," Misaki says, smiling at Bonnie, "You can side with the Oracle Think Tanks and use this deck against Emi in your first fight!" Emi looks at Bonnie, who smiles giddily. It's the same mood that the others are feeling, as each person looks at each other with confidence.
Now it was time for the group to select their own unique clans. According to the Cardfighters, on Cray, the units are divided into clans based on their traits, creatures, and battle styles. On the trainers side, Ash opts to stick with the Royal Paladins, as well as to remember Aichi. Bonnie decides to accept the Oracle Think Tank clan and loads the deck, ready for battle. Serena, based on her goals as to be the best Pokémon performer, chooses the Pale Moon clan. Clemont opts to choose the Tachikaze clan, which has science and the ancient prehistoric creatures combined into one devastating army. Meanwhile, on the Cardfighters side, Kai sticks with the Kagero Clan, where the fearsome dragons and demons roam. Misaki goes with the Genesis clan, similar to her previous clan, that Bonnie now owns. The Genesis clan relies on protectors, sorcerers, and harmony with nature. Kamui decides to stick with his trusty Nova Grapplers. With this clan, it's all about aggressive attacks. The units that are mostly associated with this clan include robotics, enhanced animals, and futuristic superheroes. Emi, despite being one of the youngest, goes with the Bermuda Triangle clan. This clan is mostly home to aquatic creatures, mainly mermaids, and they are very talented mermaids at that. In the Trainers eyes, their selected clans are just like their Pokémon. They are more friends, allies, and more resources to help find their goals. In the cardfighters eyes, the clans are similar to themselves. Together though, these units will help them find Aichi, as well as to find Total Victory in the Grand Tournament. "Well, we've all chosen our clans," Emi begins, "You know what that means, right, Bonnie?" Bonnie looks at her newest friend with no fear and a mood of a trainer or a Cardfighter should have. That mood, is to have a fight and to have an experience to remember. "Of course, Emi!," Bonnie answering back, "It's my first Cardfight!"
Around the entirety of the city, the crowd near the iconic Prism Tower, is just minding their business. Their own business is changed when someone calls out that there is something going on. The small crowd then sees a group of people, watching over two young girls, now each a few feet away from each other. The smaller crowds soon turn into one large crowd and then surrounds the small group. As the crowd comes closer, Misaki is one of the first people noticing them. "We've got an audience, Uncle Shin," she says to him, with a worried look. "Guys?," Bonnie calling out to her friends, "If this crowd is here, shall we give them a Cardfight they'll never forget?" The others nodded and steps back to the makeshift sidelines. Shin then steps forward to make the answering announcement to the entirety of the crowd. "Everyone, you are about to witness something extraordinary, it's the first ever public game of Vanguard!" The crowd is intrigued as they look at the announcer and the two opponents. "To my left, from here in Lumiose City, it's Team NXT V4's Bonnie!," Shin shouting out as if he was the announcer of a wrestling match. The crowd cheers as Bonnie loads up her gauntlet with her own deck. After Shin announces Bonnie, he announces her opponent, in the same fashion. "To my right, is her opponent, also from Lumiose City, is Team Q4's newest member, and sister to the legendary Aichi Sendou, Emi Sendou!" The crowd also cheers for Emi, as she loads up her deck. "Now that you've loaded your decks," Shin calling out to the two young girls, "Will both of you young fighters place your First Vanguard?" The two girls take one of their cards and place it on their gauntlet. As the excitement builds, the news crew comes by and the crowd expands to almost one hundred people to see this new craze in person. "I want to see a good clean Cardfight, you two," Shin says, calling out to the two players, "Are you ready Bonnie and Emi?" Bonnie nods before calling out to Emi, "Are you ready to put on a show, Emi?" "You better believe it, Bonnie," Emi calling out to her opponent, "It's time that we lift the curtain on finding our mate, Aichi, and to the beginning of a new friendship!" The crowd cheers as the two make their declarations. Shin smiles as he thinks about something, "This is it, good luck you two, if Aichi was here, he would love to see you two battle each other." Shin then adjusts his glasses as he announces to the crowd, "Everyone, on the count of three, we will all declare, "Stand up, My Vanguard!", to begin this new age of battling." The crowd waits for the countdown to begin. When the countdown began, the crowd knew what to say to get the celebration and the grand tournament underway.
"STAND UP, MY VANGUARD!"
