A/N: Because this is inspired by Ao Oni and Corpse Party, this is M-rated. The reason? It's simple: There will be dark/suggestive-related themes later on to the point of where you will question my sanity as an author, a fangirl, or maybe even both. (Well, that, and the fact that there's also really strong language.) If at any point you feel offended, then please just leave.

Nonetheless, I wanted to attempt something else for the RRBZxPPGZ fandom. I'm not sure if many of you will like this fanfic, but I hope you guys appreciate it, anyway.

Legend of the Mansion

CHAPTER 1: The Rumor

A rumor.

A mere rumor caused this all.

And yet, it's this same rumor that intrigued so many people.

Every person had the same thought: Is this true? It's not…right? At the end of those thoughts, they were each filled with doubt. Their burning curiosity continued to eat away, filling their heads with questions galore. They all started off with one: Even if the rumor was false, how did it start, anyway?

In the end, no one knew how this rumor spread.

Besides, even if they did, no one lived long enough to tell the tale.

"You two didn't have to come along, you know."

"What?! Kaoru, do you really think I'd let you go in alone?!"

"Why not? You run away whenever we go into a haunted house, don't you?"

A slight pause. "T-That's not the point!"

"Now, now, you two, don't start arguing."

"But, Miyako-chan—"

"That is disgusting, Momoko."

"What?! How?!"

"The way you added that damn honorific—"

"Are we going to enter or not?"

At once, the other two ceased bickering. Three teenagers stood a fair distance away from the mansion, and each of them were female. One of them was a beautiful light blue-eyed blonde. Her hair was in curled pigtails that reached to her shoulders. She had porcelain-like skin that matched her blonde hair. The next one had bright orange hair tied into a high ponytail that cascaded all the way down to her very bottom. A silk red ribbon was used to tie her hair up instead of a hairband. Her eyes were pink while her skin was peach, matching her orange hair perfectly. The third female had her black hair going in all sorts of directions. Although her eyes were light green, her skin was a bit tanner than the other two.

They each adorned a school uniform. Both the blonde and the redhead had on the school uniform for females, which consisted of a tucked in and short-sleeved white blouse, a black skirt that reached halfway above their kneecaps, and a very small and thin black ribbon tied underneath the collar, as though it was a necktie. The collar of the blouse lay flat on their clavicle. On the other hand, the black haired female had on a white long-sleeved shirt and black slacks. The sleeves of the shirt were rolled halfway up, just above her elbows, and the collar of the shirt stood up instead of resting against her clavicle. Although the blonde and redhead buttoned up their blouses to the very collar, the black haired female didn't button the top button, leaving it wide open. Compared to her two friends' appearance, the black haired female's look seemed more of a male's than a female's.

"You two don't have to go with me, you know," the black haired female known as Kaoru stated. "Nothing's gonna happen to me—"

"Kaoru," the pink-eyed redhead known as Momoko began, "do you not watch horror movies? They always start out like this! It's better to go in a group than alone!"

Kaoru rolled her eyes. "Whatever."

"Wait, why did you want to come here, anyway?"

"'Cause that damn Natsuki—"

"Have you been talking to Natsuki-kun again?!"

"Oh, my fucking God, Momoko. How many times do I have to tell you that I'm only friends with that asshole?!"

"Well, out of every boy that you're the closest to, it's Natsuki-kun—"

"That doesn't mean I see him as a God damn love interest!"

Momoko pouted as she narrowed her eyes at Kaoru. "And out of every girl that Natsuki-kun's closest to, it's you."

"Does it look like I give a damn?" Kaoru replied, glaring at Momoko. "The boy is an asshole. Have you not seen how he treats you and everyone else—"

"Natsuki-kun is amazing, okay?!"

Scoffing, Kaoru mocked, "You only say that because he's the so-called 'hottest' guy in school."

"Because he is! He's good at sports and he's smart and he's good-looking—"

"Yeah, to you and his fangirls. He's an arrogant asshole, Momoko, and quite frankly, he's lucky I haven't kicked his ass yet."

"I don't care! Natsuki-kun is Natsuki-kun, and I'll still like him, anyway!"

Kaoru shook her head. "You're fucking blind. Out of all of the assholes you could've fallen for, it just had to be him."

As the two continued to bicker, the blonde known as Miyako was already at the entrance of the mansion. She stared at the large brown doors for a while, tilting her head as she began to examine its outward appearance. The doors were worn out, as expected because of how old this mansion was, but it seemed rather sturdy. It wasn't just the doors. The rest of the mansion itself seemed worn out as well. Its black bricks were almost graying, and clumps of dirt clung to some lower parts of the walls. The paint on the roof tiles were beginning to peel off, showing its white, but also dirty, surface underneath. The windows seemed as clear as ever, except that they were all covered by curtains from within, so any hope of peering inside of the mansion was completely lost.

"Natsuki-kun is mine!"

"God damn it, Momoko! I said that I don't care! If you want him that badly, then be my guest!"

"But it's obvious that he's—"

"How many fucking times do I have to say that he's just a friend?! There is no way in hell he's interested in me, and there's no way I'll ever be interested in an asshole like him!"

As the two continued bickering, Miyako blinked a couple of times before walking up towards the door and placing her hand on the knob. Her eyes widened after realizing that the knob could be turned. "Momoko-san. Kaoru-san."

At once, the two ceased all of their bickering as they turned their heads to Miyako. They then simultaneously asked, "What?"

"The doors are unlocked."

Momoko and Kaoru blinked a couple of times before glancing at each other.

"Well, I'm not surprised," Kaoru stated before sighing. "No one lives in this damn mansion, anyway—"

"Wrong! Obviously, you haven't heard the rumor about this mansion!" Momoko exclaimed, pouting slightly. Immediately, her eyes were overcome with slight fear.

"Rumors are just rumors," Kaoru replied, rolling her eyes. "Like I said earlier, you guys don't have to come with me. I'll be fine."

"No way we're letting you go in alone! What if something happens to you?!"

"Oh, for crying out loud, I just said—"

"Momoko-san has a point, Kaoru-san," Miyako interrupted once more. "I don't think it's wise for you to venture inside alone."

"See?! Miyako agrees with me!" Momoko exclaimed, jumping up and down. "It's better to go in as a group!"

Kaoru sighed bitterly before stating, "All right. But for the record, blame Natsuki for this."

"What?! Why Natsuki-kun?!"

"Because he's the one that made a bet with me. My end of the bargain was going into this damn mansion."

"And if you won?"

Kaoru stared at Momoko for a bit as she hesitated before replying, "He'd have to go out with you on a daaaaaate—WHAT THE HELL, MOMOKO?!"

It was already at this point that Momoko had leaped onto Kaoru and was hugging the black haired female tightly. As Kaoru began to struggle for air because this was one of Momoko's "death hugs," as Kaoru calls them, Momoko was thanking her over and over in a gleeful voice.

"Oh, my God, I take back everything I said earlier! Thank you so much, Kaoru! Thank you, thank you, thank you, thank you—"

"Whatever!" Kaoru managed to say. "Just…let me go!"

Momoko blinked a couple of times before releasing Kaoru.

As the black haired female panted to catch her breath, she glared at the pink-eyed redhead, who was now smiling. "Get your damn ass into the mansion already."

Momoko pouted before she complied. Miyako, on the other hand, giggled softly as she headed inside as well.

Kaoru groaned before muttering about how the trio became the best of friends in the first place. As the black haired female stepped inside, she and the trio stood in astonishment of how the inside of the mansion seemed…normal. They were in a hallway that intersected with other pathways. Behind them was the entrance they just went through. In front of them, just a yard or two away, was a door. Whatever was behind it, they didn't have a clue. Next to it was a staircase that led upstairs to a second floor. To their right and left, though, the hallways led to some destination, but they were too far away to determine where each of the pathways would lead.

"Well, this is one hell of a disappointment," Kaoru stated, frowning. "I thought that there would be at least something interesting."

"I already don't like this atmosphere…" Momoko stated softly, shuddering. "Can we leave now?"

"What the hell, Momoko?! We just came in!"

"I know, but—"

"Um, Kaoru-san?" Miyako interrupted.

Kaoru turned her head, finding that the blonde had a nervous look on her face. She frowned before asking, "Yeah, Miyako?"

"Did you perhaps…closed the door?"

"No. Why?"

Miyako hesitated before pointing behind the black haired female.

Kaoru's eyes went wide for a second before she turned around and found that the doors of the entrance were completely closed.

"See?!" Momoko exclaimed. Her eyes were completely wide as she began panicking. "Oh, my God, we're gonna die—"

"Shut up, Momoko! You're exaggerating the damn situation!" Kaoru yelled, glaring at the redhead. She quickly stomped over to the door and began turning both of the doorknobs to try opening them. Unfortunately, they both refused to turn. She frowned and began trying to turn them once again. After a couple of failed attempts, Kaoru grunted in frustration and turned to the blonde and redhead before shaking her head. "It looks like we'll have to find another way out."

"Maybe we can try going out one of the windows?" Miyako asked.

"Do we even know if these windows open, though?!" Momoko exclaimed.

Kaoru glared at the redhead. "Stop shouting, Momoko! The worst thing to do in a situation like this is to panic, and you're doing exactly just that, so just shut up and calm down!"

"Well, you're yelling at me!"

"Says the girl that's panicking and screaming her ass off!"

"You two, stop shouting and let's try to find a way out of here!" Miyako exclaimed, frowning.

The black haired female and redhead flinched at the blonde's tone. Indeed, this was one of those rare occasions of where the blonde would snap at the two because their bickering went overboard.

"Honestly!" Miyako huffed softly before walking over to the nearest window. She moved the curtains aside before blinking a couple of times. Her eyes grew wide in realization before she turned to the other two.

"Well?" Kaoru asked, raising an eyebrow.

"This window doesn't have a switch."

"What?!"

At once, Momoko ran towards another window, moving the curtains aside and leaned towards the glass. "Same here!"

Miyako then checked the other windows, only to find that it was the same result: None of them had switches.

"We're gonna die—"

"Momoko, shut the hell up and let me think, for Christ's sake!" Kaoru exclaimed, narrowing her eyes at the pink-eyed redhead. After sighing bitterly, she glanced at the set of stairs and added, "All right. How about we—"

Crash!

The trio flinched at the sound.

"What the hell?" Kaoru muttered.

"It sounded like something made out of glass shattered…" Miyako stated, frowning as a look of worry appeared on her face.

"I'll go check it out, then—"

"No! We're going together as a group!" Momoko suddenly exclaimed. "This happens in horror movies all of the time! The group separates, and one by one, they all die!"

Kaoru stared at the redhead blankly for a bit. "You need to lay off on those movies."

"But, they're so addicting—"

"And anything else related to shoujo manga, shoujo anime, and all of those damn Korean dramas—"

"Hey! I watch Japanese ones, too—"

"Okay, you two, that's enough bickering for now," Miyako interrupted, rubbing her temples. "Shall we go find out what happened?"

Immediately, the other two nodded their heads and they walked down the eastern hallway. As the trio walked, they came across a black door on their left.

"Hey, there's a door here," Kaoru stated, frowning.

"Perhaps it'll open?" Miyako inquired, tilting her head slightly.

"Don't open it! Who knows what'll come out!" Momoko then exclaimed, her eyes practically filled with fear.

Kaoru sighed in exasperation at the redhead's expression and walked over to the door. At once, she tried turning the knob, but it wouldn't turn. "It won't open."

Miyako then squinted before pointing at the doorknob. "Kaoru-san, look. There's a keyhole."

"Huh. So, I guess it's locked."

"I suppose that means we'll have to find the key."

"Need I remind you that we don't know what's in there!" Momoko exclaimed, flailing her arms about.

"You know what, Momoko?" Kaoru inquired, staring at the redhead. "I think you need to lay off on believing rumors as well."

"But rumors always start somewhere—"

"That doesn't mean that they're true. Who the hell believes in the supernatural nowadays, anyway?"

At once, Momoko cleared her voice, glaring at the light green-eyed female as she was tapping her feet.

Kaoru blinked. "Oh, right, you, who finds vampires utterly 'sexy'—"

"They are, though!"

"They're dead, Momoko. You wanna have sex with a dead corpse? Oh, wait, you can't have sex with them, anyway, because they can't get boners!"

As the two bickered, Miyako sighed as she hung her head, pulling her two friends by their hands down the hallway.

"Kaoru, you just don't understand what it's like to be in the presence of someone so hot—"

"Yeah, 'cause I see no point in going gaga over some boy—"

"Not even if he was a hot vampire?"

"Hell no! That's disgusting! Haven't you ever heard of necrophilia?!"

"We're here," Miyako interrupted before the two could pointlessly continue bickering. "It seems that we're in the kitchen."

"Make that living room as well," Kaoru added as she walked over to two sets of couches and a small mini table in between the sets of furniture. The black haired female then sat down comfortably, leaning back against the pillows of the couch. "You know, this couch isn't so bad. It's pretty comfy."

"For a mansion, the furniture is rather simplistic," Miyako added, pondering as she paced slowly around the room as she glanced at the furniture and the carpet. "The carpet seems as though it's kept in good condition as well."

"Maybe someone lives here, after all?" Kaoru inquired as she leaned her head back to stare at the ceiling lights. "I mean, it would explain why the place is lit up in the first place."

"Most likely not."

Kaoru raised an eyebrow at the light blue-eyed blonde. "What makes you say that?"

"This mansion seems very old, so there's a high possibility that the mayor assigned a caretaker, or perhaps even more than one."

"True. Wait, does he even know about this place?"

Miyako shrugged in response as she then walked over to the wall, wondering why walls such as these were kept so clean because they were completely white. Not a speck of dirt was upon any of them. She frowned slightly while raising an eyebrow as she continued to examine the wall.

Kaoru, on the other hand, was still sitting on the couch and staring at the ceiling lights.

Meanwhile, Momoko looked around before finding a gleaming object near the counter. She squinted her pink eyes before smiling and walking over. Leaning down, she found that the item was none other than a plate smashed into pieces. Slowly, she reached for one of the shards and held it up before turning around. "Hey, you guys—"

Zzt!

Pitch black.

It was utterly pitched black.

The pink-eyed redhead gulped softly before calling out softly, "Um, Miyako? Kaoru? You guys there?"

No response.

She gulped softly once more before whispering to herself, "Oh, why do things like this have to happen now of all times?!" Pausing, she then added, "Calm down, Momoko. It's probably just…really bad lighting. Yeah. That's it. The lights will eventually come back on."

As if on cue, the lights switched back on, and for that, Momoko was grateful.

There was only one downside to this situation, though.

She was all alone.
