Maiami Championship

The Maiami Championship is a Dueling competition in the Yu-Gi-Oh! ARC-V anime. The event is sponsored by Leo Corporation and is managed by the "Maiami Duelist Association".

The tournament is divided into three categories: "Junior", "Junior Youth" and "Youth", based on the contestant's age. Taking part in this tournament is the first step towards becoming a Professional Duelist.

Purpose
The Maiami Championship is a cover up plan designed by Reiji Akaba. According to him, the tournament is actually an exam to select Duelists whom are strong enough to battle against his father, Reo Akaba.

Additionally according to Reiji, the upcoming Battle Royal Junior Youth finals has an alternative motive as well. That is to to stop the upcoming Fusion Dimension invasion. For that, 8 LDS top students are joining in such battle.

Requirements
To qualify for the championship, a Duelist must either have:
 * Participated in at least fifty official Duels in a year, with a win rate of at least 60%.

Tournament Format
For the start of the tournament, Duelists were required to put their tournament ID's into their Duel Disk. A computer would then match that registered Duelist to another opponent. These two Duelists would have a match and the victor would advance to the next round.

In the first round, there were 32 matches for the Junior Youth division. In the second round, there are supposed to be 16 matches for the Junior Youth Division. However, one was defaulted after Hokuto was captured by Serena.

Final 16 of the Junior Youth Division
The final 16 Duelists are engaged in a Battle Royal around Miami City using "Wonder Quartet" as the Action Field. The Duelists will also be able to find Pendulum Monsters around the city to assist them in their Duels. Similar to Duelist Kingdom and Battle City, Duelists must find at least two Pendulum Monsters to Duel against other opponents and wager them. Duelists participate in individual Duels, which can merge into Tag Duels. If a Duelist forcibly joins a duel, they receive a 2000 damage penalty for intrusion. The winner will take the losing opponents Pendulum Monsters and move on to the next opponent. The top 8 Duelists with the most Pendulum Monsters will move onto the next round. The Battle Royal will last for 24 hours. The Battle Royal began at midday with all Duelists leaving the stadium to Duel.

Final 8 of the Junior Youth Division
The final 8 participants of the Junior Youth Division are Ken Umesugi, Makoto Takeda, Tsukikage, Dennis Macfield, Noboru Gongenzaka, Yūya Sakaki, Shun Kurosaki, and Yuzu Hīragi. Even though they are the last 8 participants, they only qualified because of an invasion of the Standard Dimension by the Fusion Dimension that sealed the other 8 participants into cards. Sora sealed Hikage, Yūri sealed Halil and Olga while the Obelisk Force sealed Ashley, Carl, Bram, Michio Mokota and Teppei Tairyobata. No player really qualified towards the final 8 but obtained entrance because of the invasion.
