Hello everyone, and welcome to the third (and possibly final) installment of my FNAF and Vocaloid Crossover. I think I should give this series an official name. Anyways, I was going to simply call this a trilogy. Was being the key word, because not long after I made that pact with myself, I saw the image of Nightmare Freddy. I got a file on my reactions to the Nightmare animatronics if anyone is interested. But I'm thinking that his will still be a trilogy. Much like the Freddy F*ckboy games, I am thinking about having that as part of the Animatronics and Vocaloid Shouldn't Go Together story. I haven't entirely decided yet, but I do know what Vocaloid will be going through that nightmare within a nightmare of an experience.

Anyways, we are now out of storytelling mode, and we are with Riliane and Allen at Fazbear's Fright, the horror attraction from Hell. No one, and I mean NO ONE, is friendly, except for Riliane and Allen themselves… for the most part. Anyways, now that that's out of the way, let's get started.

Disclaimer: I own nothing. The Vocaloids belong to Crypton Media, Mothy and Crypton belong to themselves, their backstories (however) and Aoi belong to me, and all Five Nights at Freddy's 1, 2, and 3 characters belong to Scott Cawthon. This is Rated T for censored cussing (because my readers know I myself don't cuss). Enjoy:

March 15th, 2015

11:50 P.M.

Allen drove the road roller up to the parking lot of the attraction. Honestly, considering that the name has Fazbear in it, and that's Freddy's last name, something is going to happen. But, when their old friend (whom they call Phone Dude by the way he speaks) called them asking if they wanted a job there, Riliane was all too willing to take the job as part of her 'not being a total b*tch' quota that she apparently gave herself after she was a princess in her previously life. Naturally, he got dragged along as well.

They would've spent the rest of their day back at the mansion, but Gallerian texted them, saying that the Toy animatronics are there, how they got there, and that there was currently a war going on in the mansion over which group of animatronics was better. At this, Allen and Riliane both agreed not to go back to the mansion anytime soon. So they simply rented a hotel room.

And now Allen's here, in the middle of the night, outside of a horror attraction based off of what happened at Freddy Fazbear's Pizzeria, with his sister Riliane.

He can already tell that this was going to be a literal Hell.

They got there early so they could check the place out. To say that the place was creepy would be an understatement. And that was just by going on what's on the outside. The inside was much creepier. Weird lighting, artifacts from the previous pizzeria, old gaming machines that barely functioned, and they even got a hold of the original costumes that Freddy and the gang wore as animatronics. Kayo never did say what happened to their costume and endoskeleton. She only said that their A.I. was extracted from the endoskeleton. Nothing about the costumes or endoskeletons. At least they know what happened to those things.

Anyways, soon after they had that revelation, they made it to the office.

"Oh hey, look at that box!" Riliane exclaimed. Close to the doorway was a box with the costumes of the toy animatronics. Toy Bonnie, Toy Chica, Toy Freddy, Mangle, and BB's plastic shells were there. Even though the toys themselves just got to the mansion earlier that day. Kayo must have thrown the shells out and Phone Dude must have been 'lucky' enough to have found them. There was also a red guitar, and a paper plate thing that resembled BB a bit.

"Kind of creepy, you got to admit," Allen pointed out.

"I know," She said before checking the desk and, upon seeing the little figurines of Freddy, Chica, and Bonnie, exclaimed happily, "Aw! I want these! They're so cute!"

Allen couldn't help but roll his eyes and say, "You just want something to tease Freddy and Bonnie about."

Allen didn't know why, but Riliane loved to tease Freddy and Bonnie. Freddy and she has a little teasing thing that's just for fun, no mean intentions behind it. It's like her and Allen sometimes when they tease each other. The same can't be same for Bonnie. They do it for competition to see who snaps in anger first.

While Riliane adored the little figurines, Allen looked around. Attached to the wall on the right of the twin chairs was a monitor, along with one to the left of said chairs. When Allen looked at it, he saw that it was a camera. He looked over at the monitor on the left side of the other chair and saw another monitor. He went to that one, and saw that it was a maintenance panel. It was able to reboot audio devices, the camera system, the ventilation, or all three.

'Why would we be needing that…? Actually, considering how broken down this place looks already, I wouldn't be surprised if we got any kind of error.' Allen thought. He shook his head and looked at the camera monitor. He quickly learned that he could click to different cameras by clicking on the blue buttons. He saw a thing called and Audio Device and pressed it. Both he and his sister jumped when a familiar, child-like laughter emitted throughout the place.

"… You know, considering we played the second game with Freddy and Foxy, I'm f*cking positive that was BB's laugh," Riliane said. Allen felt reluctant to agree. The male blonde went back to checking the camera monitor. He pressed the button called map toggle and found himself looking at a vent. He pressed a little green line and saw that the vent sealed.

"Hm… interesting… Hey sis, there are two monitors. One for maintenance, and another for the cameras. Which one do you want to look after?" He asked, looking over at his sister (who had just stopped admiring the little figurines).

"I'll take the maintenance monitor. I honestly don't want to look at those creepy hallways more than I want to," She answered, shivering slightly. Allen didn't blame her. Just looking at the place gave him the chills. Now they was going to have to look at them for six straight hours. He really wasn't looking forward to this. But, all thoughts like that were put to the side as they both sat down in their respective seats, ready for their shift to begin.

12 A.M.

Allen and Riliane weren't surprised when the phone next to the old, metal fan rang. Phone Dude did tell them that he was going to talk to them. Of course, he also said that he was just going to let them listen to the message he had recorded for the guy who was supposed to take their job before he mysteriously disappeared. No one had seen that guy for weeks. Phone Dude just isn't the brightest and has yet to realize that.

"Hey-Hey! Glad you came back for another night! I promise it'll be a lot more interesting this time."

"I wonder who that guy was who was supposed to be doing this job instead of us…" Riliane wondered out loud. Allen shrugged. It probably didn't matter much.

"We found some-some great new relics over the weekend. And we're out tracking down a new lead, right now."

"Sounds like fun…" Allen muttered sarcastically as he looked through the cameras. Riliane raised an eyebrow at this.

"Since when were you on the Sarcasm Express?" She asked.

"Since last week," Allen answered swiftly. Riliane went 'oh' and nodded in understanding.

"So-uh lemme just update real quick, then you can get to work. Like, the attraction opens in like, a week, so we had to make sure everything works, and nothing catches on fire!"

"He shouldn't have said that. Now I'm worried about fires breaking out," Riliane pointed out. Allen felt inclined to agree once again.

"Uh-when the place opens, people will come in at the opposite end of the building, and work their way towards you, then past you and out the exit."

1 A.M.

"Uh-yeah. You've officially become a part of the attraction. Uh-You'll be starring as... The security guard!"

"Dun dun dun!" Riliane exclaimed jokingly. Allen rolled his eyes playfully and they both laughed.

"So not only will you be monitoring the people on the cameras as they pass through, y'know, to make sure no one steals anything or makes out in the corner, but you'll also be a part of the show."

"Lovely. We get to be more of an attraction than we already are," Allen said sarcastically. Riliane chuckled.

"Good one."

"It'll make it feel really authentic I think. Uh... Now let me tell you about what's new. We found another set of drawings, always nice, and a Foxy head!"

"Only he can get excited about finding a Foxy head and a couple drawings," Allen stated.

"Agreed," Riliane said, nodding in agreement with her brother.

"Which we think to be authentic... then again it might just be another crappy cosplay, and we found a desk fan, very old school - metal, though, so watch the fingers."

2 A.M.

"Uh-heh... Uh... Right now the place is basically just, you know, flashing lights, spooky props. Uh, I honestly thought we would have more by now, uh, we don't have something really cool by next week, we may have to suit you up in a furry suit, and make you walk around saying, "Boo"..."

"I would complain, but a lot of Vocaloid songs are probably worse than dressing in furry suits," Riliane pointed out. Allen nodded in agreement, faintly shivering at the thought of a lot of the songs he's sung in that were just wrong on many levels.

"*hehe*, uh... But, you know, like I said, we're trying to track down a good lead right now. Uh, some guy who helped design one of the buildings says there was, like, an extra room that got boarded up or- uh, something like that."

"Huh. I wonder why Freddy and the rest never told us about that," Riliane wondered.

"Maybe their programing didn't allow them to go in there?" Allen suggested.

"Possibly," Riliane said, looking through the maintenance monitor.

"So, we're gonna take a peek and see what we can find. Uh, for now just get comfortable with the new setup, um..."

3 A.M.

"You can check the security cameras over to your right with a click of that blue button. Uh, you can toggle between the hall cams and the vent cams..."

"Already figured that out, but thanks anyways," Allen muttered as he looked through all of the cameras to get a feel for the locations shown to him.

"Uh, then over to your far left, uh, you can flip up your maintenance panel. Y'know, use this to reboot any systems that may go offline. Heh. So, in trying to make the place feel vintage we may have overdone it a bit, hehe... Some of this equipment is barely functional."

"… Does that mean what I think it means?" Riliane asked, checking the maintenance panel again.

"Yeah, I wasn't joking about the fire. Tha-tha-that's a real risk."

"Son of a b*tch."

"Uh, the most important thing you want to watch for is the ventilation. Look, this place will give you the spooks, man, and if you let that ventilation go offline, then you'll start seeing some crazy stuff, man."

4 A.M.

"Keep that air flowin'."

"We're robots. We don't need air. Why do we need to keep the air flowing if we have no need for air?" Allen asked.

"Let's just do it to humor him," Riliane said.

"Okay, keep an eye on things, and we'll try to have something new for ya tomorrow night."

"See you tomorrow night, Phone Dude," Riliane said. Curious about the time, Allen looked at his watch. He was stunned, to say the least.

"It's already 4 A.M.?" He wondered out loud. Riliane looked at her watch to see that it was indeed 4 A.M.

"Wow, Phone Dude's talking must have really speed things up. Time does fly," She said. Allen had to agree.

"You know, there was so much information there that I'm not entirely sure how to process it all," Allen said.

"I know! It was so much, and we have so little time to register it," Riliane agreed.

5 A.M.

"I have a bad feeling about Phone Dude's lead… I'm not sure why," Allen remarked. Riliane had to agree. But then she paused as she remembered something.

"… Allen… Remember the trailer for the third FNAF game? That golden Bonnie whose name is apparently Springtrap?" Riliane asked.

"Yeah, why? … Oh…" Allen said, remembering how freakishly similar the hallways of that place was to the very horror attraction they were in right now. And the animatronic that was shown in the trailer…

"… My bad feeling from earlier just plummeted down in a straight line… F*ck," Allen said. You know it's bad when Allen curses. He never does it unless really angry, really terrified, or he just doesn't care. In this case, it's the second one.

6 A.M.

As soon as it turned six and the owner came in, the two immediately began looking for any information on the game once they got to their rented room. They found their information from the Markiplier videos. To say that they were beyond terrified wouldn't be too far off from the truth.

"… Why are we doing this?" Allen asked.

"… Because the mansion is currently the epicenter of an epic warfare that it's best that we don't become a part of. We also need more money because Conchita and Chica blew up the kitchen somehow and we need the money we did have to make repairs," Riliane answered. Allen sighed.

"… I hate it when our budget gets like this," Allen simply said, shaking his head as he and Riliane made their way back to their hotel room.

"Just remember, it's for the budget."

"Can't we just get Gallerian to get us money?"

"Not while the mansion is in the middle of World War Three. Let's wait until AFTER the war is over and after we let them to clean up the carnage."

"Good idea."

Vocaloid Name: Kagamine Len

Real Name: Allen Avadonia

Sin: Pride/Vanity (Good)

Song(s): Servant of Evil and Rebirthday

Vessel(s) of Sin: The Stones/Four Mirrors of Pride

Past Life: Allen Avadonia was the servant and younger twin brother of Princess Riliane Lucifen d'Autriche (see below). Long story short, when she asked him to kill a girl named Michaela (Miku), a girl he'd fallen in love with, he eventually went to do so in order to make her happy. But someone killed Michaela before he killed. When the angry citizens came to get Riliane, Allen switched clothes with her in order for her to live. Since they're twins, they look the same, and he is killed in Riliane's place.

Current Life: Allen makes sure the others don't commit their sins again. Which mostly involves making sure Margareta doesn't poison everyone, making sure Venomania doesn't do his 'need(s)', and making sure Banica Conchita doesn't eat everything and anyone/everyone. He's still is very royal to his sister thought, and is favored by everyone, except when he stops them from doing what they want, which usually relates to their sins.

Vocaloid Name: Kagamine Rin

Real Name: Riliane Lucifen d'Autriche

Sin: Pride/Vanity (Bad)

Song(s): Daughter of Evil (Aku no Musume) and Message of Regret

Official English Title: The Princess of Lucifer

Vessel(s) of Sin: The Stones/Four Mirrors of Pride

Past Life: Riliane Lucifen d'Autriche was a ruthless and spoiled 14-year-old princess who didn't know how to run a kingdom. Long story short, she ordered Allen to kill Leonhart Avadonia (Leon) after she discovered that he was smuggling food from the palace to feed the people affected by famine. She also started a war with Elphegort and purged the female green-haired population after Kyle Marlon (Kaito) rejected her for Michaela (Miku). Because of this, the people of Lucifenia formed a revolution that was led by Germaine Avadonia (Meiko), Leonhart's step-daughter, overthrowing her. She was forced to become repentant when Allen died in the guillotine, after taking her place to save her. After that, she went underground and left the country. Shortly after, she was found by Clarith (Haku) and eventually befriended her. She helped with the orphan kids, living a life of regret and penitence in the local church, near a harbor.

Current Life: Riliane now helps Allen with the others. She mostly is favored by Margarita and Venomania (because of his sin). She favors Allen (obviously), Kayo Sudou, Margareta, and Gallerian. She still doesn't forgive herself for what happened in her past life to her brother, so she helps him, to make up for it.

A/N: Yup. We're jumping right into it. The first night is pretty much nothing, plus I couldn't really come up with any sort of good prologue. But this is a onetime thing. Only with this FNAFxVocaloid story. Anyways, what'd you guys think? Just wait until next chapter. They have to deal with Springtrap/Purple Guy AND the Phantoms Animatronics (I know that the Vocaloids are robots and that they shouldn't really see them, but have you SEEN the Evillious Chronicles? It's a wonder why they WOULDN'T see the Phantom animatronics.) At least Allen and Riliane will have an excuse for keeping the air flowing.

Anyways, thank you all for reading and please review!
