It was a subtly warm morning, a perfect setting for the beginning of a new day. A young teenage girl in Maiami City called "Kyoko Nakano" woke up and looked at a clock. "Today's going to be a nice day!" she said in excitement. She grabs her gray Duel Disk and sits on her bed, then activates the Disk to know the weather informations. After a while, she goes downstairs for a breakfast. As Kyoko and her mother is eating the breakfast, they talked about the school life. After some more time, Kyoko left her double-story house.
After some walking, the girl noticed a rather large building. "So, this is the Maiami First Middle School." she thought. After going through the gate, Kyoko walked to the entrance of the school building. She saw a poster listing who is in what class and what attendance number they are assigned to. After brief reading, she found her name being listed in the sixth class list. "I am going to be in the sixth class? That's a long walk from the seventh grade entrance!" she thought.
Kyoko then proceeded to go to the school's gym to attend the opening ceremony, before going to her class to be briefly introduced to the school. There was nothing interesting to her while all the ceremony and introduction took place. Since the school that day was planned to end after the introduction was done and the plan went correctly, she was able to be in home by noon. After eating lunch, Kyoko went out to buy some cards before going to her duel school.
At the card store, as Kyoko was looking at Spell cards, somebody strange as observing her. Nobody seemed to notice the person. The person whispered to himself. "She moved here too? I must show her that I have changed and get my revenge..."
As Kyoko bought some cards and walked out of the card store, she was tapped by someone in her back. Kyoko looked back, and found a strange man that looks young, and wears black clothes.
Kyoko asked the man "Who... Who are you? Why did you even tap me?"
The man replied. "I am Kenta Umeda, the guy that lost many Ante duels forced by you."
Kyoko replies. "What...? What are you talking about? What is Ante duel?"
Kenta sighs, and angrily replied. "No use trying to fool me. Ante duel, the bets are the cards written on this paper."
Kenta hands Kyoko a paper with names of various cards written on it.
Kyoko sighs sightly, and replied. "So, you want to bet with cards? I don't think I have any of cards written there with the same rarity though..."
Despite Kyoko trying to avoid the Duel, Kenta insisted about getting revenge. "Then buy me these cards! Start the duel now if you are a Duelist!"
Kyoko sighs. "Fine..."
Kenta and Kyoko both prepares their Duel Disk, before shouting "DUEL!"
