When they arrived at the Domino Pier, Mai and Bakura said their goodbyes and went on their way. Yugi, Akia, Honda, Anzu, and Jounouchi headed for the hospital to go check up on Mutou Sugoroku.
While they were walking there, Akia took out the card Bond of Friendship and shoved it into Yugi's hand. "This is way too cheesy for me, so you have it."
Used to his sister's antics, he just sighed and put the card in his pocket.
When they finally arrived at the hospital, Yugi and Akia rush up to their grandfather's room, followed by their friends. They quickly opened the door and found Mutou Sugoroku sitting on his bed. Over filled with joy, the twins ran to their grandfather.
"Grandpa!" Akia yelled out.
"You're awake!" Yugi exclaimed.
"Yugi! Akia!" Sugoroku called out to his grandchildren.
After their happy reunion, they checked him out of the hospital and started heading home. On their way, they told their Grandpa what had happened and filled him in on the recent events at Duelist Kingdom.
"Hey! Are you Mutou Sugoroku?" A little blonde girl blocked their way and pointed her finger at Sugoroku. Everyone looked confused at each other, not knowing what to think of the girl. She was carrying a teddy bear and had travelling luggage with her. It was safe to assume that she had just arrived in Japan. She looked much younger than Yugi and the others.
"Yes, that would be me. Can I help you?" The elderly man inquired.
"You thief! You stole my card!" The child yelled out.
Everyone gasped at what she said.
"Grandpa is no thief!" Yugi opposed.
"Who are you, anyway, you little brat?" Jounouchi asked.
"I'm Rebecca, the American Duel Monsters Champion!" The little girl introduced herself
"They must really run out of Duelists to have a kid like you as their champion." Akia mocked.
"I'm not a kid! I'm twelve years old! Anyway, your grandfather there is a thief! He stole my Blue Eyes White Dragon!" Rebecca retorted.
"He didn't steal it!" The red-eyed girl denied her allegations.
"Shut up and hand it over!" Rebecca was starting to seriously get on Akia's nerves.
"I challenge you to a duel! If I win, you'll give me back my Blue Eyes!" The blonde little girl challenged Sugoroku.
"A duel?! He just got out of the hospital!" Akia retorted.
"I don't care!" Rebecca yelled out.
"Rebecca, I'll take my Grandpa's place. I can't let him do this while he's still recovering." Yugi offered.
The kid pouted. "Fine, whatever. I'll win anyway whether it's you or your grandfather."
The group then headed to Kaiba Corp. where they hoped to find a dueling arena that they could use. When they arrived there, the place was packed with people.
"We just had to come on the weekend..." Akia mumbled.
They looked around to find anyone in charge.
"Ah! Mokuba is there." Anzu pointed.
They rushed to him and told him about the situation.
"Hmm... Well, we're really completely booked today, but maybe... I'll make a special exception for you guys, since, without you, Seto and I wouldn't even be here. Follow me." The younger Kaiba brother told them. They followed Mokuba to an indoor arena that was completely empty. "This arena is not open to the public yet. Just make sure you don't mention this to Seto, he doesn't like to give any special services."
"Thanks, Mokuba, you're a big help." Yugi expressed his gratitude.
"Don't sweat it." The boy replied.
After Mokuba left, Rebecca and Yugi took their spots on the dueling platforms. The duel started off with Rebecca summoning Witch of the Black Forest (1100/1200) in attack position. Yugi then easily destroyed that monster with his Celtic Guardian (1400/1200). Due to the effect of Rebecca's monster, she was allowed to add one monster with 1500 or less defence to her hand. As the duel went on, she summoned other monsters with the same ability to get another monster from her deck. To reinforce her defences, she summoned Millennium Shield and equipped it with the spell card, Ring of Magnetism, making it the only attackable target for Yugi with a defence of 2500. Yugi, however, managed to destroy it using Mind control then using his Catapult Turtle's effect to tribute Millennium Shield.
Rebecca then used a card to discard five of the cards in her hand to destroy all the monsters on Yugi's side of the field. After doing that, she summoned Shadow Ghoul that was powered up because of all the monsters that Rebecca had in her graveyard. After lasting a few turns, Yugi unexpectedly surrendered.
"Why?! Yugi never surrenders!" Akia exclaimed.
"You win, Rebecca." Yugi told his opponent.
The twins' grandfather then took out the Blue Eyes out of his pocket. Sugoroku had taped it where Kaiba had torn it. Rebecca's eyes widened in shock at the sight of the card. She then snatched it from his hand. "How could you?! You ruined it!"
"It wasn't his fault, it was...!" Sugoroku put his hand up to stop Akia from continuing what she had to say.
"I'm very sorry about what happened, Rebecca," the twins' grandfather started apologizing, "this card was given to me by someone very important to me, and I should've taken better care of it."
"I've had enough of your lies! It wasn't given to you; you stole it!" The impertinent child was starting to throw a fit.
"Rebecca!" Everyone then turned to the voice that came from the entrance.
"Grandpa!" The blonde girl called out in surprise.
"Arthur, is that really you?" Mr. Mutou inquired.
An old man in a suit came in. "Sugoroku, my old friend, I apologize for my granddaughter's behaviour."
"I had a feeling she was your granddaughter." The twin's grandfather replied.
Arthur then turned to Rebecca. "Rebecca, give back to Sugoroku his card."
"But I won the duel, so it's mine! Besides, he stole it from you!" Rebecca retorted.
Arthur then went up to Yugi's deck that was still on the platform. "Did you know that Yugi would've actually won that duel if he had played his next card?" While saying that, Arthur picked up the card, which was revealed to be Soul Release. "Had he played this card, you would've lost. He could've removed up to five monsters from your graveyard, which would've considerably weakened your Shadow Ghoul."
"He..." Rebecca trailed, realizing what her grandfather was saying.
"Also, Rebecca, Sugoroku did not steal the card. I gave it to him as a sign of our friendship." Mr Hopkins explained.
Rebecca looked shocked at the revelation. Arthur Hopkins then turned to Yugi. "You're just as kindhearted as your grandfather."
Yugi gave out a nervous laugh. He then went up to Rebecca and gave her the card that Akia had given him earlier.
"What's this?" The little girl asked.
"Just a token of friendship. I'm sorry for everything that happened." Yugi replied.
Rebecca looked at Yugi and blushed. "Friends...? Thank you..."
With that, Sugoroku spent some time with his old friend while Akia and the others went back to their respective homes.
