Suddenly Became Part of the Akatsuki [Itachi, Deidara, Sasori, ? x Reader]

Summary:

[inspired by that time i got reincarnated into a slime and sugar sugar rune]
One minute, you’re a stressed-out psychology major just trying to pass your lessons—and the next, you’ve been yeeted into the middle of Naruto Shippuden. Surprise! You can go home… but only if Itachi, Deidara, and Sasori all fall in love with you. No pressure or anything.
Now you’re dodging kunai, analyzing shinobi trauma in real time, and trying not to fangirl over literal war criminals.
P.S. There’s a secret fourth love interest, and he's more dangerous (and emotionally repressed) than all three combined. Good luck!

Chapter 1: entering the naruto world???

Chapter Text

BOBO DOLL EXPERIMENT ESSAY: MISSING ASSIGNMENT
STATUS: CONCERNED
DAYS MISSED: 20

        Her laptop, placed on her bed, presented the following words in bold capitalized letters. With the comfy blanket wrapped around her body under the dark lit room, her heavy bagged eyes scanned those warnings accompanied with the bright flashing screen light as if it was the norm.  

        [Real First Name] [Real Last Name] was a psychology major first year student (well forced to as she was not interested in other majors) from [University Name]. Not the best student out there. Seen as per above, she was in a way almost failing her classes. Her professors wanted no more to do with her attitude and her lack of responsibility, her classmates had been avoiding her, and her parents had completely cut ties with her, always complaining why she could not be like anyone else. 

        But she was used to it. Although at first she was sunk deep into deep depression, she could find her way out to her light. That was watching and reading Naruto. Naruto, one of the best-selling manga series about ninjas and pursuing his dreams to be the best ninja in the world within the manga community, was her most favorite manga of all time. Manga and anime? Watched them all. Naruto merch? Brought them all. Doujinshis? Read them all. However, it was not merely a matter of preference, she was actually infatuated with three of the Akatsuki members: Itachi Uchiha, Sasori of the Red Sand, and Deidara. She had always been rematching the arcs where those three appeared before they were killed. She could understand because they were the antagonists of the story (except for Itachi if you know what I mean), but she had always thought those three characters still had more potential to develop as they were killed to early.

        She had always thought that it would have been better if she could exist in that world and helped them develop their characters. Having those ninja abilities would be very cool to use too, but that was a mere childish thought. As she made a conclusion of not going to class today as usual, her phone with an unknown number rang.

        “Hello?” she said. It was unusual for her to receive any calls as everyone completely avoided her.

        “Hi. You’re [Real First Name] [Real Last Name], right? I’m Fuwa Shirotani a new counsellor of the university. I heard that you haven’t been coming to school for quite a while and have been missing deadlines. If you’d like, you could come talk with me.”

        She has had multiple counseling before, but none of them were effective. She had a feeling that this talking with him would be the same.

        “I’m sorry, but I don’t want to talk to anyone.”

        “I understand that previous counseling have not been successful, but I have many suggestions that could maybe fix your problems. You would be much more relaxed if you have someone to talk to.”

        In a way that was true. However, she had this lingering feeling that she had to visit him. It had never happened before. She was not going to do anything today anyways.

        “… Okay then. I’ll go.”

 

        Knock! Knock!

        After hearing a soft “come in”, she entered the new counsellor’s room with her hands slightly shaking. It was a bright, spotlessly clean room, with his desk filled with neatly stacked textbooks. The counsellor, who was sipping a drink from his cup, stood up from his desk, and gave her a small smile and shook hands with her. He was a pleasant-looking young man in his formal clothes, with hazel eyes and short raven hair. He drew up a chair for her near his desk and seated himself just behind. 

        She did not know what to say. She was also quite sleepy as she had pulled up an all nighter the day before. 

        “So, how are you feeling today?” he asked. He clasped his hands in front of him.

        “… Not well as usual.” She started to feel uncomfortable. His somewhat basil-scented cologne was spreading into her nostrils.

        “There’s no need to be so tense. Let’s talk about something interesting. I heard from your mother that you enjoy reading manga. Naruto, was it?” 

        She did not know that he had been contacting her mother.

        “Uh… yes.” She was not very sure where the conversation was heading.

        “Actually I’m also a big fan of that manga series. I still remember waiting for the new chapters when I was still pursuing my degree.”

        “I see…” 

        He stood up.

        “I do know that you’ve been very unmotivated lately. So what if…” he leaned towards her ear,  “I told you that you could spend your time in the Naruto world?”

        She froze. The direct closure was one thing, but just what did he mean by the latter?

        He shifted back to his chair and let out a small laugh.

        “Don’t be that surprised. What I’m saying is the truth. What do you say? Would you like to live in that world for the time being?” His eyes bored into hers.

        She leaned back a bit. Just what was he saying? How is that possible?

        “… How can I trust you?” she asked timidly. Staying in the Naruto world used to be one of her dreams, but that was definitely impossible. “But I mean it would be nice to spend time there.”

        He grinned. “Then, I’ll take that as a yes.”

        With that said, he made several Naruto-looking hand seals that resembled the Summoning Jutsu and slammed his hand down to his desk. Black inked Japanese characters formed around his hands. Puffy white smoke exploded with a loud bang, covering her vision. 

***
        Coughing from the smoke, the young woman woke up, realizing that she was lying down on her stomach on the brushy rough surface. Her hands felt leafy textures around her fingers, and could feel a faint smell of dirt from her nose where her face has been slammed into. She stood up with widened eyes as the smoke cleared up.

        The desk, textbooks, and chairs of the counseling room had vanished. All she could see was tall, evergreen trees with their branches dancing with the cool wind. Soft chirps of birds echoed in the air. The azure sky had some blotches of white clouds floating within in. The sounds of the water running down the lake was pleasant to hear.

        Where the hell am I? 

        She looked at her hands, and saw that it looked the same. But she could not be so sure. She ran towards the lake that was glittering in seven colors from the reflection of the sun. She looked down into the water. Her face was different. Her hair colored changed into [hair color], her eyes were [eyes color], and she was wearing a kimono-looking blouse held close with an obi, long shorts, and shinobi sandals. She looked around Deidara’s age.

        Wait… HOW CAN THIS BE? Am I really inside THAT Naruto world? She touched her face as if she never knew who it was that was reflecting from the water. She pulled her cheek to see whether it was a dream but only to feel a stinging pain in that area. Realization sets in. She was not in that human world anymore. 

        She landed on her knees. What could she do now? How could she get back? Her mind was muddled with thoughts. But really, was she in the Naruto world? By simply wearing Japanese style attire would not represent anything.

        ANSWER. Yes, you are now inside the Naruto world. Naruto Shippuden to be exact. 

    A voice echoed in her head. This voice… she had heard it before. It belonged to her counsellor, and Naruto Shippuden?

        ANSWER. Yes, I was Fuwa Shirotani, but now you must call me the Great Sage.

        Great Sage? Just what do you mean? you asked in your mind.

        I’m the one who will be guiding you during your time in this world. Just to make sure you understand everything, you are currently a ninja who has the Kekkei Genkai that allows you to use any nature transformations. You can also analyze anyone’s abilities and mimic as your own.

        Nature transformations and analysis? If she could use any, then her character would be very overpowered. Is it really what she should have? However, since she had the skills, she would have to try some.

        As a test, I would like to try Kakashi’s Chidori.

        HAND SEAL ANALYSIS COMPLETED. The Chakra Nature is Lightning Release. Chidori is an offensive attack where high concentrations of electricity is accumulated to the user’s hand and can cause fatal damage to the target. The hand seals are: Ox → Rabbit → Monkey.

        A sudden rush of information surged through her mind—precise images of hand signs and the flow of chakra. Moving almost instinctively, she raised her hands and formed the seals one by one, just as instructed.

        The moment she completed the final seal, a sharp tingling spread through her right hand, followed by a burning sensation, electric and alive. A high-pitched chirping, like the cry of a thousand birds, pierced the air as blinding light crackled in her palm—raw lightning dancing between her fingers.

        She stood in awe. It was real—she was actually inside the world of Naruto Shippuden.

        Turning her gaze to a nearby tree, she dashed toward it, her hand now crackling with lightning. With a swift thrust, she slammed her Chidori-charged palm against the trunk. The bark disintegrated instantly, and the tree split in two, one half crashing heavily to the ground.

        Oh my gosh. It worked!

        Overwhelmed with excitement, she jumped and skipped in giddy circles—only to trip over her own feet and plunge headfirst into the nearby lake with a loud splash.

        Cold water blurred her vision as she sank deeper and deeper. Tiny air bubbles drifted past her face, and her legs, already tired, kicked feebly against the weight of the water. Panic surged through her chest as her lungs began to burn. How deep was this lake? She couldn't tell. All she knew was that she was sinking—fast—and she didn’t know how to swim.

        Am I really going to die like this? Just float around like seaweed until my body rots?

        No—there had to be a way out. Her mind raced.

        Wait! I still haven’t tested the extent of my Kekkei Genkai. Guren’s Crystal Release… what was it called again? Crystal Wall Formation? Something like that!

        HAND SEAL ANALYSIS COMPLETED. The Chakra Nature is Crystal Release. Crystal Wall Eight Formation is an offensive attack that crystallizes a large area and everything within it. The hand seals are: Rat → Dog → Horse → Ram → Boar → Dragon → Rat → Ram → Boar.

        With her remaining strength, she swiftly weaved the hand seals.

        A brilliant flash of light erupted from the lakebed. Suddenly, [favorite color]-colored crystal began forming beneath her, spreading outward in symmetrical lattices. The water around her solidified with a chorus of sharp, crystalline cracking. The growing structure surged upward, lifting her rapidly toward the surface.

        She burst into the open air, gasping as her lungs greedily drank in oxygen. Lying flat on the gleaming crystal surface, soaked and breathless, she realized how close she’d come to drowning.

        Looking down, she saw the entire lake had been transformed—solidified into a breathtaking sheet of [favorite color] crystal, refracting light into shimmering rainbows. What incredible power...

        Finally, she slid off the mineral surface and collapsed onto the grassy shore, her breaths shallow and quick.

        Why am I feeling so tired? Did I use too much Chakra?

        ANSWER. Because you’ve used two Chakra natures, you’ve lost 30% of your Chakra. To replenish your Chakra, you must rest for at least 30 minutes.

        Okay. That’s fine. Although she could use any Chakra natures, there were still some limitations. She had to be more careful from now on. More importantly, she had burning questions that needed immediate answers.

        Hey, Great Sage, why did you bring me here and how can I get out?

        ANSWER. To get out from this world, you have to accomplish a mission. You must locate and join the Akatsuki—and make Itachi, Sasori, and Deidara fall in love with you.

        She blinked. WHAT???
