My first crossover! Okay, this idea just came to me and I had to write it! Enjoy! I don't own Yugioh or Yugioh GX.

Judai cringed as the man pulled the trigger. His eyes widened in pain as the bullet embedded itself in his shoulder. Clutching the wound, he doubled over in pain.

"Judai!" he heard his friends cry out from behind him.

Judai squinted at the assassin through the pain. How did we get into this mess? he wondered.

Several days earlier...

"Hey, guys!" Judai said cheerfully to his friends as he entered the classroom. It was the last day of school before summer vacation, and Judai couldn't wait for the day to end.

"Hi, Judai," Sho said with a smile.

Asuka didn't say anything. She didn't even look at Judai. Honestly, she looked like she was in a bad mood.

"Hey, Asuka, is something wrong?" Judai asked, cocking his head.

"Mind your own business!" she snapped at him before walking away.

Johan turned to the startled Judai and said, "Don't mind her. She's just in a bad mood because Fubuki has this crazy idea to go on a treasure hunt."

"A treasure hunt?" Judai asked, cocking his head.

Johan nodded. "Apparently, he got a treasure map from a girl he met and wants Asuka to help him find the treasure this summer."

"Wow, sounds cool! I want to go with him!"

"That's the spirit, Judai!"

The three boys jumped at the voice behind them: Fubuki Tenjoin. They turned to face the upperclassman, who stood right behind them as if he'd been there the entire time.

"What are you doing here?" Sho asked, shocked. "Shouldn't you be in your own class?"

"I just wanted to ask you three to join Asuka and I on our fantastic adventure!"

"I'm not going!" Asuka snapped, sitting at her desk across the room. "And you shouldn't either! That map is fake, Fubuki."

"Well, Judai is up for an adventure, at least." He turned to Sho and Johan expectantly. "What about you two?"

They thought about it for a moment before deciding that it could be fun and agreeing to tag along. Asuka mumbled something about idiots and shooed her brother from the room.

Judai grinned at his two best friends. "Well, I guess we know what we're doing this summer!" he said excitedly.

After school, Fubuki told them to pack up and be ready to head out in the morning. "We won't be back for awhile, so just tell your parents you're going camping. Oh, and Ryo is coming, too."

Judai went home and packed for the trip: clothes, food, water, a flashlight, and a few other things he thought he might need. He wasn't sure exactly where they were going, but that was what made it an adventure! It was going to be fun either way—going on an adventure with his friends during summer vacation.

He was too excited that night to sleep. He spent the whole night lying there, wondering what the treasure could be and if they'd actually find it. Finally, morning came.

"Judai!" his mother called. "Breakfast is ready!"

He bolted down the stairs to the kitchen.

"Morning, son," his dad said. "Sleep well?"

Judai sat down and scarfing down bacon and eggs. His parents just laughed.

"Judai, what have I told you about eating like a wild animal?" his mom asked.

He swallowed and apologized. "Oh, by the way, my friends and I were gonna go camping this year. Fubuki's taking us. You know, Asuka's older brother? Sho's brother's going, too. Is that okay?"

His parents looked at each other.

"I don't see why not," his dad said at last.

"When were you planning on doing this?" his mom asked.

"We're leaving today," Judai said, getting up. "Thanks for breakfast, see ya!" he called, running out of the room.

"Judai!" his mom called after him. She sighed when he didn't answer. "Talk about short notice. What is wrong with that boy?"

His dad laughed. "Boys will be boys, won't they?"

"I suppose."

Judai got dressed in shorts and a T-shirt, grabbed his bag, and ran out to meet the others at the school, their decided-upon meeting place. When he arrived, Johan was already there. So were the Marufuji brothers. All three were dressed in jeans. Johan wore a blue tank top, Sho a yellow T-shirt, and Ryo a white one.

"Hey, guys! You ready for this?" Judai asked, walking over to the other three.

Johan and Sho nodded, looking enthusiastic. Ryo just sighed as if he didn't really want to be there. "I suppose," he said dully.

"Hello, fellow treasure hunters!" Fubuki called as he joined them. He was dressed like he were going on a safari, including the hat. "Are we all ready? Then let's go!"

He started walking off, the other four following suit.

And that was how their latest adventure began.
