Hello, this is an OC reincarnation fic for Assassination Classroom. This OC is not from our world and therefore does not know the future.

This story is written on a whim, so updates will be sporadic and the chapters will be short. Like literally I saw shirtless Karma and just went "whoops time to write a new OC fic".

I'm weak, sue me.

Anyway, I hope you'll like this fic!

Enjoy reading!

She's a cheater.

Not in the very literal meaning of it; but if she's to put it lightly, she cheats because she has foreknowledge while others have none, that is all.

For Kotonoha Shiori, her life is a second journey.

She's lived before, as another person who studied, who dreamed and thrived, who lived and died.

She may have gradually forgotten some things as her new life progresses on, such as her old name, her friends and even horrifyingly of her past family members' names, as well as some personal events, but she certainly doesn't forget the repeatedly taught lessons of mathematics, science, world history, social studies, English, and many others.

She has shown great intelligence and cognitive development as a child, or so her parents think, when it was just her teenager mind doing the deed, who thought and did stuff some kids her age probably won't be able to.

It's a bit embarrassing, and she thinks it's unfair because she's not a child, not exactly, and even when they put her in an expensive and top-notch elementary school, she thinks she doesn't really deserve it.

Before, she had to study very hard to even pass some subjects. But now, simply because she obviously knows simple multiplications or even can read in English, she's suddenly labeled as a genius by her parents.

Yes, she thinks wryly, I'm definitely a cheater.

She wonders if someday, she'll get into a place where there is new knowledge for her to take, new stuff for her to learn, so she will have to try hard for it again, so that she will have to climb up with her full effort again.

She misses it, somehow, the days of studying and learning something new, something exciting.

In her fifth year in elementary, she gets a classmate she's never had the joy of being in the same class before.

Asano Gakushuu.

As a child, he shows promise, and already there's some talk around him from the adults about the budding of a genius. It's also a plus that Asano seems to be very charismatic; he seems to be able to be friends with everyone, while she simply focuses on her small numbers of friends and keeps on herself most of the time.

Being reborn does that to you: hanging out with snot nosed brats terrifies and amuses her on equal levels sometimes.

She wonders, sometimes, as she watches Asano who sits a few seats away, if he's also a reborn person, or if he's just a genuine, smart kid who tries hard to be better and better, to be the best of the best.

Because he does; try hard, that is. While he takes part in sports like many boys his age, he's also often seen with books he reads fervently if he's not talking to anybody.

In the end, curiosity wins over, and in one fine lunch break, she asks him casually as she stands in front of his desk.

"Hey, what do you think of rebirth?"

Asano Gakushuu looks at her, and there's recognition in his eyes as he blinks, before a smile—pretty mocking, she realizes in slight confusion—breaks out, the boy saying, "I don't believe in such nonsensical things, Kotonoha-san."

Even his speech is very eloquent, she can't help but think.

Though, it does answer her question.

So with a smile and a nod, she gives him her thanks and walks away.

He knows her.

Kotonoha Shiori, rank one in class, beating him by few overall scores while the both of them are often playing a game of cat and mouse in terms of individual scores for some subjects.

He knows she has weakness in mathematics—she seems to be lacking the focus and accuracy for it—and science, but seems to triumph in others.

Sometimes, it pisses him off that someone beats him by several scores.

Sometimes, he feels happy and accomplished when he manages to beat her in some occasions.

Other times, he's just intrigued.

Because she doesn't look like she cares that much. Because he knows grade is everything—especially in the middle school his father owns, the one he's going to get into once he finishes elementary—but she doesn't seem to really care.

When she gets a less than satisfactory score, she usually simply blinks, looks over the test, and nods. But there's that. There's only surprise, not anger nor disappointment in herself, no fear of being scolded by parents, no fear of failing to be at the top.

Sometimes, he wonders how that can be possible.

Other times, he chooses not to care.

Most times, he chooses to try to defeat her.

He wants to be at the top. He wants to win, and in this class, Kotonoha Shiori is a worthy opponent to face, albeit an uncaring and oblivious one.

By the end of the sixth year, he'll be in the first rank, and she'll be second.

Sometimes, she wonders why Asano bothers to talk to her outside of necessity. She only approached him once to make sure about the rebirth stuff, but Asano somehow manages to worm his way in her small circle of friends, albeit not a very close one.

But then, a friend is a friend, and Shiori isn't going to turn such a charming boy away.

Though it baffles her sometimes that the boy is very polite, considering his age. Perhaps it's because of his upbringing? She did hear his father is a principal of sorts. Nevertheless, Shiori doesn't dabble her thoughts much in it, simply accepting Asano's sudden presence near her easily, smiling at him and studying with him (because apparently that's another thing he likes most besides soccer).

And then, they become… close, somehow.

Asano doesn't open up much about him, she notices. Shiori doesn't really give him any important personal matters too—like her rebirth, for example—so she doesn't really care. She does talk most of the time, while Asano gives answers and reactions here and there.

They do, however, like to discuss about the things they find in books and articles or even the news, and it once again baffles her on how an elementary kid—albeit a sixth grade at that—can be so socially woke.

Around this age before her rebirth, she must be way too busy about puberty kicking in and boys.

This just proves more about the genius of Asano's mind, really, and she kinda admires him for it. One time around near the end of sixth grade, she manages to tell him about it.

"I think you're really awesome, Asano-kun," she says to him, smiling softly at the surprised look in his eyes. "Not a lot of kids your age can do what you're able to do." Though it's mostlikely thanks to either his upbringing, his studying style or his genes. After all, while grades play a huge part in life, she holds onto the belief that after school, it's not only grades that people see, but talents, social skills and many others.

"Why," Asano chuckles, looking like he cannot decide whether to be politely embarrassed or preen, "you're also in the top ranks, Kotonoha-san."

Shiori shakes her head. "There will be a limit on how much I can do," she says, genuinely surprising Asano once again, "there will come a time when I'm in the same position as everybody and have to climb my way up once again."

Asano's mind whirls at her words; what does she meant exactly by that? There's a limit on how much she can do? This is not an RPG game, she's not a mage. He's at loss, unable to really decipher what she meant by her cryptic words—and it pisses him off a little bit too, because Asano is a curious person by nature and when there's something that he cannot solve, he wants to peel every layers off just so he can get his answers—but also prideful enough not to make himself seem like he doesn't understand what she meant by her words.

But judging by her small smile, she seems to know that he's confused, which simply irritates him a bit more.

"Anyway, are you going to Kunugigaoka after we graduate, Asano-kun?"

Asano blinks. "Yeah, my father is the principal there and there will be more competition in that school. Why? Are you going there too?"

"Mm," she nods softly, "I didn't want to, but my parents said it will be a good experience. They also said I need competition," she shrugs then, "I'm not really into it, really."

The orange-haired boy frowns, "Why? Competition is fun. It's even better when you win."

"You really like winning, don't you?" She casts an amused gaze at him before replying, "I'm more worried about disappointing my parents if I cannot keep up, since I heard Kunugigaoka is a bit fast paced," then she mutters, "and I don't really work well under pressure."

But they were very nice, she remembers. Her second set of parents are very nice, and when she told them about their worries, when she told them that there's a possibility she cannot keep up with Kunugigaoka's fast-paced method of learning, they told her loud and clear that they do not expect her to always be at the top.

"Even if you fall, you'll get back up, won't you?" Her father said, ever the realist, "It's important to know the taste of failure, so you won't get too full of yourself."

Her mother had scolded her father then, something about being demeaning toward their "pure, innocent and kind" daughter, but Shiori had laughed and hugged them, and promised to at least try to do her best.

Asano hums in front of her, but doesn't say anything more. There is a glint in his eyes, though, and Shiori can only wonder why.

Time passes, tests are given and done with, and they finally graduate, with Asano sitting proudly as the first rank in class. He is called forward to receive a reward from the principal, smiling all the way.

Shiori congratulates him, of course, and he congratulates her in return, although there's the usual jab toward her apparent rank right below him, that she expertly ignores with a smile and a laugh; Asano has always been prideful after all, so this is a normal occurrence whenever he, as he puts it, 'wins'.

Inwardly, she wonders why she cannot see his father around.

Spring comes.

Clad in a brand new uniform, she sets her way to Kunugigaoka. This is her first time in a prep-school, so she doesn't really know what to expect. Other than the fast-paced class, she hopes things aren't much different from the private school she used to attend in her first life.

(But she's wrong).

(She very, very wrong).

Thank you for reading!

Do you like it? This is just written on a whim so…

Next chapter, we will see Kotonoha Shiori's downfall and the things that will eventually lead her to class E. Because yes, she's going to Class E. Not only because of plot, but also because of her character trait. You'll see later.

Review please!
