This is just some crazy idea my sister gave me. I hope you like it! I don't own YuGiOh because I'm not Kazuki Takahashi.
Yami groaned in annoyance as he put down the phone. All of his friends were busy; Jonouchi was visiting his sister, Honda was tagging along (whether Jonouchi liked it or not), and Seto was babysitting little Yugi Mutou while his mother and grandfather visited sick relatives on the other side of the country (he had been babysitting for the last few days, and the family wasn't due back until tonight). Meanwhile, Yami had nothing to do. Except avoid that annoying girl who had moved into the house next door last week.
Speaking of that girl, wasn't it just Yami's luck that he would run into her when he was all alone?
"Hey, Yami!" Yami groaned when he heard that voice; he hardly knew the girl, but Seto—who was in her class at school—said that she was a pest. Then again, Seto thought everyone was a pest. Still, his judgment on this one seemed spot-on.
Yami turned to see a spiky-haired Egyptian girl standing behind him. She was wearing a blue tube top and a matching skirt. Her green eyes gleamed with excitement as she looked at Yami. She didn't know that Yami hated her.
"Hello, Mana. How are you?" Yami forced himself to be polite.
"I'm great, aside from being bored. What about you? Where are your friends? It's weird seeing you without them."
Yami wanted so badly to lie, but this girl always knew when he did. "They're busy right now," he mumbled.
Mana's eyes lit up. "Great! Maybe we can hang out then!"
Yami winced. That was not something he wanted to do. At all.
He was spared from answering when his phone rang. He answered; it was Seto.
"Kame Game Shop. Get over here. Now." With that, he hung up.
Completely baffled, Yami turned to Mana and told her he couldn't hang out with her; something had just come up. She looked disappointed, but Yami ignored it and ran off.
When he got to the shop, Seto came out holding a toddler under one arm. He walked over to Yami and thrust the child toward Yami. "Here. Take it."
Still confused, Yami took the child, Yugi, and asked, "What's going on? Can't handle him for a few more hours?"
"Change of plans. Apparently, there's a bad snow storm, and they're snowed in. They can't make it back tonight, and I can't stay here taking care of this thing any longer."
Yami chuckled. "Seto, he's just one kid! You have a younger brother, and you can't handle a three-year-old kid?"
Yugi interrupted, "I'm four!"
Seto grimaced at the boy. "I'm telling you, he's not human! He's a monster."
Yami shook his head and sighed, "Fine. I'll take over. Have you told his family you're ditching their kid?"
"Taken care of. Good luck. You'll need it." With that, Seto bolted off down the street.
Yami shook his head, laughing. He looked at Yugi and said, "Well, let's get you back inside."
An hour later, Yami knew what Seto had been talking about: The kitchen was covered in spilled sugar, milk, cookies, and Yami didn't want to know what else; toys were scattered all over the living room floor, including puzzle pieces, blocks, and a few broken pieces of toys; and don't get Yami started on the rest of the house—he didn't want to think about it!
"How could this happen?" Yami asked as he glanced around the house at the ruin Yugi left in his wake. "This place was spotless just a little while ago!"
Yami glanced at the little boy lying asleep on the floor. And how could this kid fall asleep so soon after destroying everything in sight? Yami had brought Yugi inside and placed him down on the floor. As soon as his feet hit the ground, Yugi had run to the kitchen and grabbed the cookie jar. He had eaten half of the contents, then thrown the rest on the floor. After that, he burst into tears. Yami tried to calm the kid down by saying they could make some more. Yugi's face lit up, and he quickly grabbed the milk from the fridge. Then he grabbed the sugar container, which he dropped on the floor before spilling the entire jug of milk.
With the kitchen thoroughly destroyed, Yugi moved into the living room (the cookies he had lost were completely forgotten). He started working on puzzles, but wouldn't sit still, and the puzzle pieces were scattered around the room within a matter of minutes. Giving up on the puzzles, he moved on to some blocks. Again, he wouldn't sit still, and he tried to build a city. Once he was finished building, he grabbed a stuffed dinosaur and had it destroy the town, scattering the blocks around the room. He trod on several toy cars while he was running amok, and he burst into tears when he realized that he had broken his toys. Yami was getting a headache, and he was failing to calm the kid down when Yugi stopped crying and fell asleep suddenly.
Now Yami was left with a serious mess to clean up. With a sigh, he picked Yugi up and carried him to his room. Once Yugi was tucked into bed, Yami started cleaning. If this was how the kid always was, he hoped the family would be home soon.
The phone rang. Yami picked it up. "Hello?"
"So you're the new babysitter? Yami?" a woman's voice said.
"Yes, that's me."
"How's Yugi? Is he doing all right?"
"Don't worry, Mrs. Mutou. He's fine."
He was about to ask if her son had ADHD or something, but the line went dead. Yami groaned, not looking forward to the rest of his time with this kid.
The next day, Yami woke to a small child jumping up and down on him. "Wake up! Wake up!" Yugi chanted as he broke Yami's ribs.
"Get off!" Yami bellowed at him. The boy's eyes watered, and Yami sighed. "Look, I'm sorry I shouted, but you really shouldn't be jumping on people. You could hurt someone. Okay, Yugi?"
Yugi nodded and grinned at Yami. "Can we go to the park? Please?"
Yami groaned as he rolled out of bed. The clock said that it was only seven in the morning. "Are you always up this early?" he asked Yugi. The boy just grinned.
A short while later, they were at the park. Yugi was playing in the sandbox with some other kids while Yami sat on a park bench, glad to see the kid not destroying everything in sight.
"Hey, Yami!" He groaned inwardly.
"Hello, Mana," he said dully. "I can't talk right now—I'm babysitting."
Mana glanced at the spiky-haired boy in the sand and said, "Is he your brother? He looks just like you."
Yami hadn't noticed this—he was too busy trying to control the kid to even realize that they had practically the same hair and the same eye color.
There was an outburst on the playground. Yami looked to see that Yugi had just been hit by one of the other kids. Yami got up to go deal with it, but Mana beat him to it. She walked right over to the kids.
"Hey, if you can't play nice, you have to leave," she said to the offending child. Then she turned to Yugi. "Are you all right?" Yugi nodded, sniffling.
Yami gawked at her. He hadn't known that she was at all good with kids. As Mana came back over, she grinned at the look of awe on Yami's face.
"I've done my fair share of babysitting. If you need any help, give me a call." She wrote her number on a piece of paper and handed it to Yami, who was determined not to call this girl no matter what. The last thing he wanted was an annoying foreigner showing up and making his job more difficult. He was sure she couldn't handle this kid any better than he or Seto could. She would just get in his way.
Yugi had watched this little exchange, and asked Yami about it on the way home later. "Who was that girl? Is she your friend?"
"No. She's a pest who's always trying to get on my nerves."
"Oh. Well, I liked her. Can she come over today?"
Yami glared at Yugi. "No. Never. She can never come anywhere near you or me. Not in the same room, not in the same building. Trust me, she's not what you think she is."
Yugi was quiet for a moment. "Maybe," he said finally, "she's not what you think."
Yami rolled his eyes, thinking that this kid could not possibly know anything about that pest.
Later that day, Yami was chasing Yugi around the house. There were feathers and honey all over Yami's body. Yugi had decided to "tar and feather" Yami, and the boy had sacrificed his mother's pillows to do so, along with several jars of honey in lieu of tar. Now, Yami wanted to strangle the kid.
"Get back here, you little brat!" he bellowed as Yugi bolted around the corner into his bedroom. Yugi slammed the door, hitting Yami hard in the face. Yami cursed under his breath, rubbing his nose. "Fine, stay in there!" He heard Yugi cry out in fear behind the door. Yami huffed and stormed off to get cleaned up.
Several hours later, when Yami had calmed down, he went upstairs to apologize to Yugi. The boy was sitting on his bed, but he jumped up and started apologizing as soon as Yami walked in.
"It's okay, Yugi. Just don't do anything like that again, okay?"
"Okay!" Yugi seemed thrilled that Yami wasn't mad at him anymore.
That didn't last long. Within an hour, Yugi had devoured every sugary thing in the house.
"Yugi, come on! Calm down already!" Yami pleaded with the child as he tried to get him to stop jumping on the couch; Yugi ignored him.
"Yami, look, I can fly!" he said as he jumped off the couch. Yami's eyes widened in panic. He darted forward and caught the boy just before he hit the floor.
"Okay, you, I think it's time for bed."
"No, I'm not tired!" Yugi wailed. "I wanna play! I wanna play!"
Yami fought with the boy and his sugar rush for half the night. Finally, Yugi fell asleep. Yami sighed and took Yugi to bed. Then, he checked the emergency numbers and found the hotel where the Mutous were staying.
"Hi, this is Yami. Don't worry, Yugi's fine. I was just wondering, when will you be able to make it back?" His eyes widened when Mrs. Mutou said that it could be another week before they were home. "A-alright. Thank you. Bye." He hung up the phone, and silently prayed that he could make it through the rest of his time with this crazy kid.
