A/N: I have not wrote fanfiction in foreverr but I was watching Pewd's play Corpse Party this morning and I couldn't help but think...what would Sam and Dean do in this situation? And so that inspired this crossover which honestly I'm surprised no one has wrote a Corpse Party/Supernatural crossover before o-o But anyway, without further adieu, let us continue onto the story :D

It was a typical Friday night for the Winchesters, they had just returned back to the bunker after a case that had almost cost them their lives AGAIN and needless to say, the brothers were worn out. Dean opened the fridge and grabbed a beer then flopped onto a chair with a groan as Sam sat at the dining room table with a sigh and powered up his laptop before leaning back and rubbing his tired eyes with one hand.

Dean arched an eyebrow at his younger brother from his spot at the chair as he popped the cap off of his beer. "What are you doing now?"

Sam took a breath as he clicked on google chrome and leaned forward in his seat to better see the computer screen. "Work."

"Work? Dude, we just got back from a nearly 72 hour case! Can you relax for just once?" He took a swig of his beer.

Sam rolled his eyes as he typed up something in the browser. "Relaxation doesn't come with the job description, Dean. Besides, I might have picked up another case."

Hearing this, Dean groaned as he sat up straight and set his beer on a table and leaned forward. "Oh perfect, who needs sleep nowadays anyway? You know, I was actually missing my bed and it's memory foam."

Sam sighed, "You can sleep on your memory foam bed soon I promise, but something really needs to be done here."

"Okay, fine, whatever. So what is it anyway?" Dean got up and went over to Sam. He then peered over the younger's shoulder in order to get a look at what his brother was seeing.

"Check it out. Apparently there have been a lot of cases of missing teenagers ranging mostly from Middle to High School age in Japan in the past few years after they printed out some type of 'Sachiko Ever After Charm'. According to a blogger who created it, you're supposed to have a group of 2 to 9 people and they chant 'Sachiko we beg of you' one time for each person and if the ritual is performed correctly supposedly you're granted 'eternal friendship'."

"And if it isn't performed correctly?"

Sam shrugged, "No one really knows. But it seems logical that is what has caused the disappearances."

"Sounds like a lot of made up bull if you ask me. You sure this isn't some sort of wild hoax or somethin'?"

"Well how about we try it out and see? I mean, can't hurt nothing right?"

Dean shrugged and gave a short nod, "Guess not. But to be on the safe side, I'm gonna gear us up cause it seems like all the weird shit likes to happen to us." He went to the kitchen to grab some salt and prepare the holy water as Sam read through the blog on how to perform the ritual.

By the time Dean returned, with loads of Salt, Holy water, and two guns loaded with rock salt, and of course the demon-killing knife, Sam had printed and cut out the Sachiko ever after doll. Dean arched an eyebrow at the object. "The hell is that thing?"

"It's the charm. We have to both take a piece of it and say 'Sachiko, we beg of you' one time for each person holding it then we rip it." Sam explained.

Dean rolled his eyes. "I feel like a freaking idiot."

"You're not the only one. But it's better to be safe than sorry right? If nothing happens we'll just pretend this never happened, deal?"

"Deal."

Sam nodded and took a breath, "Okay, so you ready?"

Dean sighed. "I guess..." He and Sam both took hold of the charm on opposite sides.

"Alright, so there's only two of us so that means we say it twice."

"I know Sam, I'm not an idiot. Let's just get the stupid thing over with."

The boys repeated, 'Sachiko,we beg of you' twice before pulling the weird doll apart. Then there was nothing but silence as the two held the small piece of scrapped paper in their hand. "Well? That it?" Dean asked, looking around the room.

Sam looked confused. "I don't get it, I guess maybe it was just some-" before he could finish his sentence, the whole room started to shake and his eyes widened.

Dean automatically gripped onto his supplies. "What the-?!"

"It's the charm! I think- I think it's doing something!" Sam said, bracing himself for anything.

"Well no shit I'm pretty sure rooms don't just shake for no reason! But WHAT is it doing?"

Sam shook his head, "I don't-AHH!" just then the two began to fall. Fall into a deep deep abyss of the unknown. Once they landed there was a heavy impact then darkness. And silence.
