Trapped in a box [Multifandom Fanfiction]

What's inside the box

Hiro's POV

"Come with us. We'll just have to remove that trauma out of you." Naruto smiled at the guy. "What's your name?"

The guy looked at him. "Kaneki. Kaneki Ken."

They shook hands. We all smiled. Then we heard a voice. Like someone is about to announce something.

"Well well well. The guests are already complete." Said the person with a creepy voice.

I saw Rapunzel backed away in fear and Elsa was holding her hands tight. Naruto furrowed his brows as well as his friends. Sora and Shiro looked like they don't give a crap about it. They just smirked.

"Since you are all here, might as well tell you what this place is." the guy said and continued. "This place doesn't really have a name. All I could tell you is that it's a program. Where all of you will be joined to defeat the enemies of each members. You won't be able to get out here until you defeat all of them."

Right as he finished his sentence, I heard a weird noise coming from Naruto. I saw him with... a clone? When did that happen?

They formed something that is color blue that shaped like a ball in his hand. Naruto flew to the ceiling and aimed it.

"You bastard! I'll kill you!" right then, the ceiling was destroyed but then it was reformed back to normal. "Damn it." Naruto cussed.

"Naruto!" Sakura shouted.

The guy laughed evilly. "This program will only be destroyed once you defeat all of your enemies. If one of you dies, then you'll be stuck here forever."

Hiccup said, "Do you know how many people are dying while we're here? Huh? Do you know what you're doing?!"

"Why do you care? It's not like your father's going to di-- oops. I said too much. Hehe." He said evilly.

"Wh-what?" Hiccup said and panicked.

"Damn you bastard! Stop messing with us already!" Jack shouted.

"Let us out of here! Please!" Elsa pleaded.

"Oh. What a pity for you, Queen Elsa." he said. "or should I say, the Snow Queen."

Our eyes grew wide. We looked at Elsa who was also shocked.

"H-how did you know?!" She asked.

"I've got resources. Why do you care? Your Highness?" He laughed again.

"Tell us what's happening already!" Merida shouted.

"Don't worry about your families and friends. The time in your place is completely frozen. So when you've returned, it'll be just like the way you left."

We sighed in relief. "But, if one of you dies, then you're stuck here and they die." He laughed again.

"You're so annoying! Let us out!" Sakura shouted.

"God! You're so annoying! I already told you! There's no way out. Are you so stupid?!" He mocked.

"Damn it."

"So, the only way to return to our worlds is to defeat every enemy we have?" Sora asked.

"Yes."

"And if one of us dies, they die and we're stuck here forever?"

"Absolutely."

"Are there any excluded enemies?" Shiro asked.

"Yes. Hiccup's, Hiro's, Merida's and Rapunzel's enemy."
