Yo! Hi, hi! Crazy Adamantine here. So, my little sibling and I had been roleplaying a whole other story, which distracted us from our collaborations on my sibling's profile. I have finals coming up, so I might not be able to get back to those collabs or even my story, Missing. What am I doing with a loose FNAF AU, then, if I should be studying for finals? Got to get the creative juices out before I can study. How did this AU come to be? Well, it began with talking about Balloon Boy, then Baymax's nickname being Balloon Man, and one thing led to another.

This story features myself and my sibling as OCs! Hope you enjoy, do tell us what you liked, and I'll post the next chapter tomorrow!

P.S. The robots and part of the setting in this story will be the ones seen in FNAF 2, but the year won't be 1987 and the backstory of possessed animatronics won't be that of the original FNAF. This is only for the sake of this AU.

Ryan sighed and rested his head on the desk, dreading the night to actually start. He came in two hours earlier, watching as the restaurant closed up and he was already scared, especially when recalling his sister's own experiences as the night guard. She said these animatronics moved around at night. He wasn't sure what that meant, but it couldn't be good.

"Remember, Ryan! You can put on your mask whenever you want to!" his sister had told him when she explained how to ward some of them off. He sighed again, already missing her. She had gone missing just a week after she started her job here, and no one could find her. Maybe he could find out what happened while he's here?

He sighed for the third time and stared down at the papers in front of him. Empty. All empty. Where was she? "Why did I let you work here?" he asked quietly. "If I just helped you find a new job, you wouldn't have gone missing..." That wasn't entirely true, she could have been kidnapped, but the footage showed that she never left the building... Maybe she was somewhere in here… But why would she be? His sister would never stay here for longer than she needed to. She did admit that she didn't like the spookiness of the place, though she did find the animatronics cute, for some reason. Well, they didn't call her Crazy Kerry for nothing.

One. The clock struck an hour before midnight, an hour before his shift started. He was so screwed. Just a couple of minutes ago, he could have sworn he heard a music box in the distance, but that may have just been him. He began to write a couple of things down.

"I took her place in the job. Might as well, right? I mean, if I'm going to find out where my sister is, I may as well start from where she was last seen. I hope nothing bad happened to her..." The more he wrote, the colder the room felt, almost as if something else was there. Was this the spookiness that Crazy had talked about?

A shadow fell over Ryan's paperwork. It looked short enough to look like a boy or a girl with really wild hair. In any case, a child was here. "Get lost, kid. The restaurant's closed," he said grumpily. The shadow didn't move. "Didn't you hear me? I said get lost!" He looked up and found that the kid in front of him was transparent! "HOLY MOTHER OF—" Ryan never got to finish his sentence and he fell out of his chair. "Is this a damn prank? Hologram?" The boy smiled sadly at him, never speaking. Ryan sighed and stood up, brushing dust off and he sat back in his chair, beginning to write again. "No, I don't think holograms make shadows..." he began muttering some things to himself and his mind slowly went back to what he was thinking about before.

"Are you the new guard?" asked a rather timid voice. Ryan continued to ignore him. "Hey, I know you can hear me. You see me, too." No answer. "Can you help me?" Again, Ryan didn't answer. He had no time for hallucinations. "Please? I lost my brother and I want to find him." Those words made him freeze. That was the same situation he was in... He lost his sister and he wanted to find her... "Can you help me?" Ryan sighed and looked up at the boy. He looked about 5 years younger than he was.

"Sorry for being rude, but I don't think I can help," he answered finally. "I have to survive six hours of this place and I still have to find someone else."

The boy seemed at least satisfied that the night guard was paying attention now. "But I haven't seen him in so long. Can you at least help me get out of here?" he asked, putting his hands together as he pleaded. "I might help you find whoever you're looking for in the process. What did they look like?"

Ryan pulled out his phone and began scrolling through his photos. He came across a photo of a girl with short, messy, nearly-black hair. The picture was definitely at a birthday party and the cone hat was a huge clue.

"That's Crazy. She's my older sister and she disappeared a week ago," he said. "It probably hasn't been as long as your situation, but I still miss her."

The boy looked at the picture and his expression turned into one of grief. "She looks younger than I remember," he said sadly. It caught Ryan off guard. Did Crazy meet this boy before? And why was he so sad upon mentioning her?

"You know where she is?" the guard asked hopefully. "Mom and Dad are worried sick about her." The boy only looked away, staring at something else. He looked almost guilty about something.

Suddenly, the phone rang and a message began to play. The voice was feminine... Crazy?! "Yo! Hi, hi! You the new guy? Or girl? Bleh. The point is you're new! Okay, shall we get to the good stuff or the not-so-good first? Oh, I'll tell you the good stuff. Welcome to Freddy Fazbear's Pizzeria!" The phone call began a long explanation that Ryan had already heard from his sister a long time ago.

The guard picked up the phone. "Crazy? Crazy, are you there?!" he practically yelled, but his sister kept talking. "Oh... This must be a recording..."

The boy started looking really upset about something, almost as if he knew something happened but he didn't want Ryan to find out. "I haven't seen my older brother in so long," he said again. "Can I stay here with you? Maybe he'll come by and pick me up. T'dashi said that if I ever get lost, I have I stay with an employee and he'll find me."

Ryan wasn't sure what to say. Does this boy know that he's transparent? Like a ghost? Maybe he was dead... "S-sure," was all he could manage to say. He didn't let go of the phone, as if hoping that Crazy was just messing with him and was only pretending to be a recording.

Her voice continued on. "Now, there's a little something you should know about the characters. They like to move around a bit," she said. "Oh, but they're really cute, so there's no need to worry! They don't even look scary in the light! Well, I heard they like to scream a lot. I hope they're not into jump scares. Oh shoot!" There was the sound of a mask being pulled on and then some robotic movement that eventually faded away. "That was close. They don't seem as friendly as they are cute. Ah, but they're easy to handle." The message eventually stopped after a little more rambling and there was an awkward silence.

The boy remained motionless. "Uh... My name's Hiro," he introduced himself as if trying to lighten the mood. "Hiro Hamada, student at SFIT. Well, I used to be. They don't seem to accept applications from ghosts."

So it seemed that he knew he was dead. Couldn't he just move on then? Didn't anyone else see him? There was some supernatural shit going on right now. "Ryan Forest. I thought it would be better to get a job while going to school, which sucks because classes start at 10 in the morning, but I need the money for support. Apparently you can't get a dish-washing job around here. This was the only place with a job opening. Spooky."

Hiro laughed a bit. "You made a poor career choice, then," he said, though he felt bad right after. "Sorry... I forgot your sister also had this job." His expression had gone sad again, and Ryan wasn't sure if he wanted to ask what had happened. Maybe it's better if he found out for himself.

"It's fine. I'm used to jokes like these," the guard said. "Crazy liked to tell them all the time. She even has this way of telling dirty jokes without even knowing it." He chuckled at the memory of texting her while she was watching a movie. How naive she was…

"Sounds like you two get along really well," Hiro said, his mood lifting a bit.

Ryan only shrugged. "She could be an ass sometimes." The time passed as they both got to know each other. Hiro was a nice kid, though he had a habit of breaking the law sometimes. Everyone did it, though.

The clock finally struck twelve and Ryan's shift began. He was looking through the cameras and every five seconds, he'd be winding up a music box, though he wasn't sure how that really worked.

Hiro hummed along with the music box. "I love this tune," he commented. "My brother used to sing it as a lullaby." He checked the vents and the hallway for Ryan, making sure no robot would be there. Of course, he'd prefer not to see them and he would like to make sure they didn't see him, so he stayed hidden under the guard's desk. "Did your sister ever sing you a lullaby?"

Ryan shrugged. "She told me stories instead," he said. "The Greek myths were my favorite to listen to. She practically remembered them by heart."

"Which myth was your favorite? Wasn't there one you liked the most?" Hiro questioned. Ryan didn't bring his eyes from the cameras.

"Well I absolutely hated Zeus. Damn god can't keep it in his robes, but I liked the Titan War the most; how it started, what happened, and how it ended. Mustard and wine still stands out. That's just gross." Ryan laughed at the thought of Kronos barfing out a ton of babies.

Hiro listened, but he couldn't really understand what the man talked about near the end. "Eh... Okay," was all he could say. "What was that about mustard and wine?" Suddenly, he noticed movement in one of the vents. "Ryan, left vent!"

Ryan pulled on the mask and waited until the spirit gave the okay that it was safe. "It's a common story. Kronos ate all of Zeus's siblings and many years later, Zeus gave him a mix of mustard and wine I make him barf babies." When he received an odd look, he smiled. "Sounds strange, doesn't it?"

Hiro feigned nausea. "Blech!" Well, it would only make sense to mix mustard and wine to get someone to throw up. "Did Zeus find out his siblings were digested? Or not even there at all? There's no way his siblings could still be in Kronos' stomach."

"Titans and Gods work differently, I guess. They were all still there, covered in saliva, and I'm pretty sure I would have thrown them in the ocean before anything else. Just the thought of it is disgusting, but hey, Kronos barfs babies. That's something you don't get to see all the time."

"I guess," Hiro laughed, and then he glanced down the hallway. "Fox!" He pointed to the flashlight button for Ryan. "Shine a light at it!" A few moments later, the fox bot was gone. "Sheesh! If I was alive, I would have made better robots. Then this restaurant would be thriving."

"I bet. I can't believe kids like these things," Ryan muttered and he went from room to room, still winding up the music box. He knew that song. It was a popular one. Kerry took a liking to it when she first heard it an soon, so did he.

"Do you know it?" Hiro asked. "The song, I mean."

Ryan shrugged. "Yeah, I know it. Crazy showed it to me and it became one of our favorite songs," he said as he continued to wind. "It has a lot of emotion in it." Once it was wound up, Ryan checked other cameras. The animatronics were no longer in their places. He had only encountered two so far. Where were rest?

"Hi." Oh. The piece of shit Balloon Boy. The damn the was back. The moment he laid eyes on it, he hated it. By gods it was just the worst thing he'd ever seen in his life. The eyes were creepy, too. Ugh, Balloon Boy better rot in hell.

"I hate that thing," he growled and checked the cameras. BB was still in the vent, headed for him. "I hope you die, Balloon Boy."

"Hehe. I don't think anyone was fond of him," Hiro said. "He kept messing with the lights, then the fox would come out. I have to say it was kinda funny seeing people run for their lives." He didn't want to go into detail about those who got caught, though no one was seriously injured, thankfully. "The fox is really fast. Reminds me of my brother's friend. She has a thing for speed."

That reminded him if three things: Sonic, Lightning McQueen, and jacksepticeye because SPEED IS KEY! "Well maybe being slow is frustrating," he said shrugging. "Because it is to me." The ghost smiled a little and Ryan almost felt like he wasn't in a life and death situation right now.

In the midst of their contentment, Hiro noticed something on their ceiling, twitching. "Ryan, mask on!" The guard wasted no time in doing so and the robot eventually wandered out. Hiro could have sworn it looked insulted, as if maybe it knew somehow that the mask is only a mask.

Ryan took off the mask once again and he sighed. First day and he was already thinking of quitting. This place was spooky, no doubt, but he needed to find Crazy. He needed to find his sister, she could still be alive. But where?

"If I can see a god damn ghost," he muttered. "I'm probably already dead."

"You sure look alive," Hiro said, and then he made a move to poke Ryan. His hand just went through. "I can't touch you either, so you're pretty much alive." He checked the vents and the hallway again while the guard rewound the music box. "What time is it?"

"I don't know and I honestly couldn't care right now." There was a thump in the vents, indicating that there was something trying to get to him. Ryan growled a little and cursed, trying to keep the music box alive. "Hold on, you little shit—"

"Hi." Ryan turned on the light for the left vent and saw that there was no one there. Stupid BB. "Hello."

"Shut up." Ryan was getting annoyed and soon began to check through the cameras. Winding up the music box once again, he started to hum the tune as it went.

Hiro decided to check for him. It was 1 AM. "Five more hours," he muttered. For a while, they stayed silent, with Ryan checking cameras and winding the music box while the spirit checked the hallways and vents. "Have you ever thought about walking around and exploring?" he asked after some hours passed. "Finding secrets and all?"

"Nope," he replied, not even casting a second glance at him. "I mean I want to, but I have a job to do, you know. I wish I could leave the post, but I'd only get to do it in the daytime. Even then, I still have to go home, sleep, and go to class. Haven't you ever explored before?"

Again, Hiro said nothing. At least, not for a while. "Yeah, but I couldn't really search," he admitted. "Had to rush through each room and all."

"You said you remember Crazy, right?" Ryan asked, recalling what the ghost had said about his sister. "Did you hang out with her like this? Like, you helped her out just like you're doing with me?"

Hiro nodded slowly. "Yeah, I used to hang out with her. She was like you, she could see ghosts," he answered. "That's why I turned to her. She promised to help, or at least try. And she got farther than I did. She knew what she was doing most of the time."

Of course, the guard thought to himself. Crazy would of course help a ghost. "What did she know?" Ryan asked. He also wanted to ask what had happened before his sister disappeared, but he felt that that might be rushing it. "Maybe I can go even farther."

"Well she wouldn't tell me," Hiro muttered. "She just..." he wouldn't finish his sentence. Instead, he sighed and looked at Ryan, giving him a clear message that just kind of told him that he didn't want to talk about it.

"You know what happened to her," Ryan said.

Hiro was about to say something, but then the clock struck and it was six. "Your shift is over," he said simply. "You'll be here the next night, right?" He was hopeful and had a forced smile. Ryan wasn't sure if he wanted to know why.

"Sure," the security guard said as he packed up his things. "I'll be back tonight. Besides, I'm still looking for Crazy." He left the building without another word and sighed. He had classes and the first thing on his mind was the fact that he had been talking to a spirit for more than so hours. Ryan felt slightly distressed at that. "I'm not going I get any sleep, huh?"
