Welcome everyone! This is something I came up with while my muse for Naruto, the Kryptonian Ninja was away, and I couldn't really focus on writing the next chapter while the idea of a crossover between Naruto and Doki Doki filled my mind for the most part (I still wrote like 4000 thousand words for chapter 5).

Now, this serves as a kind of introduction for what I'm planning. The pairing will be Naruto x Monika x Natsuki, as I think both girls can relate to our blond hero the most. More author notes can be found at the end of the chapter as usual.

Disclaimer: I don't own Naruto or Doki Doki Literature Club.

Intrusion

Monika was surprised.

No, scratch that.

She was shocked to the core.

Her heart had frozen in something akin to fear when the player, the person who was supposed to control the Main Character's every decision from his computer, had somehow broken the 4th Wall and entered the game, twisting the boundaries of what the other girls considered to be reality. She couldn't blame Sayori, Natsuki or even Yuri for their ignorance, as they weren't aware of actually being fictional characters of a sickening, horrible world created by someone who was known as the "Developer".

After being spawned as the rest of the club's characters in the Literature club's room, Monika had expected everything to go like usual; the MC making his entrance in the room, and everyone else (including her) sliding into the player's vision from one side of the screen, adopting different pre-designed poses and expressions to go along with their fixed dialogues.

What she didn't expect... was to suddenly find out that she and the rest of the members could walk around freely and make other facial gestures. Surprising as it was, she found herself being able to look down at her own body and around the room, control her actions, her movements, and even touch and use other things that were not supposed to be there before, like the tea set and cups that Yuri used to prepare and serve some tea. She could even grab one of Natsuki's homemade cookies in her hand, feeling it rough and yet gentle to the touch, and take a bite, muching on the delicious sweet dough of vanilla with chocolate chips.

Her eyes had widened in both shock and astonishment when she could feel the warmth of the dark liquid in her tea cup entering her body, relaxing her senses. Her nose had picked different smells as well, and she found herself silently inhaling the distinct strawberry scent that Natsuki's pink hair was impregnated with, probably due to her choice of shampoo.

Said girl had blushed in embarrassment and turned in Monika's direction, stuttering as she asked why the president was doing such a thing. Her only response was a gentle smile which quickly unnerved Natsuki, forcing her to let it slide.

It was clear Monika had been the only member to notice these changes, as every girl was acting as if their recently acquired authonomy was not something new — like it had been a part of them the whole time. They didn't even realize that the faceless boy with brown hair and pale skin who represented the MC had been replaced by a handsome male teen with a pair of oceanic blue eyes attatched to a masculine visage with six marks like whiskers on each cheek and a mop of spiky golden hair.

She silently saw that the rest of the club's behavior was pretty much the same according to the personality given to them by the Developer, yet they'd unusually change their dialogues and come up with creative responses according to the way this player, whose real name was Naruto, interacted with them.

Monika could barely conceal her curiosity, her surprise and... fear.

Apart from the fact that he apparently had managed to achieve the impossible by coming into the game, Naruto looked at her through the entire meeting as if he knew. But there was no way right? Even after finding out she could now do and say whatever she wanted, Monika stuck to most of her script, introducing the club to their new member. Monika would more often than not forget words during her welcome speech as the blond opted to sit by her side instead of Sayori's, making sure his eyes were at all times fixed on her face. And she couldn't help but feel intimidated by those precious orbs that seemed so surreal yet mature and filled with anger. Anger clearly directed at her.

It was when she finally decided to call it a day and have the game continue normally that she realized Naruto was not leaving like he was supposed to.

"You go on ahead Sayori-chan", she heard Naruto say somewhere near the door, "I must speak with the President."

Upon hearing his words, plus the tone he used to refer to her, a shiver went down Monika's spine. She was kneeling by her bag and putting all her stuff inside when she heard it, and it was then that her previous suppositions turned into shocking realization:

The player called Naruto was truly there, in the game. And he seemed to know she was aware of Doki Doki Literature Club being a mere visual novel.

"Um... I-Is everything alright, Naruto?"

"Hmph. If you were planning to ask the president on a date, then don't bother! I'm sure she has better things to do than to go out with a pervert like you."

"Mou~ You were supposed to walk home with me today! Can't it waaaait~?"

Monika tried to pretend she was not listening, but the fact that the player was causing the girls around him to have their pre-programmed dialogues altered by his mere presence was very alarming. Neither Yuri, nor Natsuki or Sayori were programmed to say such things; Monika had seen their scripts, and they certainly should have followed their basic routines.

In fact, whether Naruto stayed or played along, each one of them should have stuck to their codes and continue in the very same way they were supposed to. A change so drastic would be considered as a kind of bug by the game and it'd instantly crash.

Yet not only everyone acted in untypical ways, but she could also feel something was going on beyond the walls of the classroom. Something that Monika assumed was related to the player's sudden intrusion into the game.

Given everything that she'd witnessed so far, the brown haired president was beyond surprised at this point.

"No, it can't."

His simple response caused Sayori to pout dejectedly, Natsuki to cross her arms over her chest and frown and Yuri to nod in silence, placing a hand on her chest in apparent worry. All of this was seen by Monika out the corner of her eyes, and it was mere seconds later than the three girls relunctantly left the classroom, with Naruto waiting until they were gone before closing the door.

The look on his eyes as he turned his head in Monika's direction was shadowed by his golden hair, and the girl couldn't help but tense at the silence that now loomed over the classroom. Never in her existence as a game character had she felt something like what she was experiencing at the moment.

Monika tried to calm herself as he stood in silence. It was impossible that he knew. He hadn't even played the game before, as she had immediately checked Doki Doki's status as soon as the player had iniciated the application. No save files were found... so how? She tried accessing Doki Doki's code, but it soon proved to be a worthless effort as she could no longer reach to it.

It was like the invisible cable connecting Monika to the code had been disconnected from her, and plugged into someone else.

Taking a deep breath, the girl with long light brown hair tied into a ponytail with a white bow stood up and faked a gentle smile, one that would have convinced any character in the game of her role as the "beautiful, kind and helpful president of the Literature Club".

But Naruto was not them.

"W-Well Naruto", Monika began, managing to get a hold on her emotions. Despite having been initially conceived as a program, she was self-conscious and capable of feeling in pretty much the same way as a human being would, that ability recently improved by gaining complete control over her body and mind. "Is there something I can help you with? If this is about the Poem task, I may be able to give you a few tips to—"

"I know what you are."

Her heart suddenly thumped violently on her chest as she widened her emerald orbs, her mouth slightly agape in shock. Upon noticing her silence, Naruto smirked and took a step forward in her direction, then another, and another.

Until nothing but mere inches separated their bodies.

"W-What...?"

He lifted his sight until his sparkling sapphire eyes bore into hers, showing her a range of emotions that spoke volumes of how he felt at the moment. Monika took several steps back, not being able to speak or even tore her sight from his expression; her adrenaline mixed with fear nearly overwhelmed her now, and Naruto seemed pleased to have caused such a reaction on her as he towered over her figure, shortening the distance whenever she tried to get away from him.

In a matter of seconds, Monika felt her back touch the board of the classroom, yet Naruto never stopped until he slammed his palms next to both sides of her head, preventing her from going anywhere.

"Ah! N-N-N-Naruto?"

The blond haired teen smiled at her, yet that gesture was far from being gentle or reassuring. "I know what you did", Naruto leaned very close and whispered those words in her ear, making her shiver under him. His hot breath tickled her, and she'd have blushed at both that and the handsome teen's proximity if not for the fear she was experiencing right now. "Or what you'll do in this case... Seeing that Sayori is still alive and well."

Monika gasped in shock. "How... H-How do you-!?"

"I know everything that is to know about you Mo-Ni-Ka", Naruto pulled his head away from her ear so that he could stare into her precious green eyes, a pair that he'd had grown to dislike as a player. This time, she gulped and tried to avert her gaze, only for the blond to grab her chin and roughly turn her head back to him. "And I just wanted to let you know... that I won't let you hurt or take the girls' lives again."

His sapphire orbs seemed to shine under the orange, reddish light of the sunset that filtered in the classroom through the windows, and despite feeling nervous and scared, Monika couldn't help but blush. A warm sensation unlike anything she'd ever felt before spread over her entire being, making her squirm under his powerful stare.

Even in the situation she now found herself in, Monika felt slightly happy. Happy that someone from the outer world, the one she'd been dreaming about ever since she found out she was a mere character in a game, was there with her. Someone that was alive, unlike herself, and knew what it felt like to do anything and go anywhere he wanted.

And Naruto was a boy around her age, a very handsome boy as well, who was bolder and much more determined than Monika would have ever imagined the player being in real life.

"I... I...", she opened her mouth, but no words managed to come out. She wanted to say something, anything, that could express how she felt at the moment, or at least try to defend herself, though that did not matter much to her. There was so much she wanted to ask, to know! Her curiosity was immense, almost as immense as everything this boy was making her feel.

"There's a new administration in Doki Doki", Monika was slightly surprised and even disappointed when the boy pulled away from her and took a few steps back, one of his hands finding its way into his pocket. The other was slowly raised up to his shoulder, and he held both his thumb and middle finger together. "And there will be major changes around here."

With a snap of his fingers, Naruto grinned devilishly at the green haired girl, who couldn't help but recoil against the board, fearing what would happen next. However, and after a couple of moments in which nothing seemed to have changed, Monika noticed the boy gesturing towards her body.

Her head followed his eyes and soon enough, a gigantic blush spread on her cheeks, making her face so red that she'd have put a tomatoe to shame. She had been stripped off her uniform, with only her fancy white panties and bra covering her body from Naruto's amused stare.

"KYAAAA!"

Monika fell to her knees and tried to cover her precious parts with her arms, which didn't really matter as the blond had already taken a good look at her gorgeous figure.

"Convinced now?", Naruto let out a laugh and turned around. "I'll be in charge from now on, thus I'd advise you not to waste your time trying to go against me", the blond slid the door open, ignoring a young girl who was busy attempting to protect her dignity. Yet, and before he left, Naruto tilted his head towards Monika. "Oh, if I were you... I'll wait until it gets dark before going home. As I said, things are going to change around here... a lot. See you tomorrow Buchou!"

With a thud, the door was closed, leaving behind a brown haired girl whose features lighted slowly until she was all but grinning in pure joy despite her embarrassment.

She had finally met someone from the real world! Her existence would be so much more interesting now...

N°1: So yeah, this is something I wrote in just a few hours after having played Doki Doki Literature Club and going through each ending. It was both a seriously creepy game, but also one that left me thinking about each character's problems. Especially Monika and Natsuki, since I felt like Sayori was somewhat manipulated at some point by Monika to immerse herself deeper into depression.

N°2: I feel like Monika, in spite of having been conceived as a possessive, manipulative and twisted character is just someone who truly desires the player's love and affection, or at least that's what I imagine her like within the game. I think this dating sim in particular was good at the beginning, and after playing Natsuki's route I felt like Naruto could relate to her in a lot of ways. Well, both to her and Monika, hence why I came up with this idea and decided to give it a try.

I know this may have been a bit confusing to you all, but don't worry. If I continue this story I'll explain everything in detail in the next chapters.

If you liked it and want me to continue to see where this will go please let me know, I think this could turn out to be a heartwarming story, in spite of having two girls paired with Naruto.

As always, don't like don't read. Good criticism will be read and fully taken into account as I myself know to accept my mistakes and take any advice that can help me improve; flamers will be dutifully ignored, so don't waste your time.

Until next time, Karai.
