Summary: In a world where 80% of the population is gifted with quirks, there are those gifted with quirks that make them center stage. Halyn Leander isn't one to let her quirk force her into the lime light. That being said, she's not above raising a little hell in everyday life. Say hello to the hell raiser of UA.

Author Note: Hello, everyone! For those of you who don't know me, I'm Kyandi Akatensei. Just call me Kyandi-sama! For those of you who do know me, welcome to another of my stories. I've been branching out lately into various of different types of animes. When I came across My Hero Academia, well...I lost it. My first thought was of how much the anime reminded me of the movie Sky High. Which, if it isn't obvious, is a favored movie of mine. And then I saw the arrangement of awesome characters and I couldn't help coming up with another characters. And thus, Halyn was born. So, yeah, compliments are greatly adored, constructive criticism is welcomed, but please...don't flame me. I've only just begun to gain a sense of confidence. I'd like to protect it if possible. Next chapter I'll start with my usual character interactions, so please, enjoy and review. I do not own My Hero Academia.

Chapter 1 Transfer Student

It all began in Keikei City in China with the news that a bio-luminescent baby was born. After that "exceptional" individuals began popping up all over the world. The cause was unclear. Time passed and the "exceptional" became the norm. Fantasy became reality.

At present, eighty percent of the world's population consists of super-humans with special abilities. The world is in chaos. And a profession that everyone once only dreamed about, entered the spot light.

Along with the exceptional abilities came an explosion in the crime rate. While nations struggled to overhaul their legal systems, brave individuals took up the mantle of heroes straight out of the comic books, protecting the people from evildoers. With public support, some quickly acquired the right to serve as heroes in an official capacity.

Depending on their performance, they have the potential to earn government pay. Fame and glory.

And that was what lead several to the location that Midoriya Izuku currently found himself in.

It was only the first week of school, just the third day in class, and already he was feeling the pressure. After the mock tag team battles from the day before, the whole class had a pretty good understanding of each other and their abilities, just as their teachers did. Day three started, though, with an announcement that none of them had been expecting.

"So, yeah...we have a new student joining our class today."

It was the first thing Aizawa said to them after taking roll. Several of them had noticed the addition of another desk to the classroom when they had walked in, but no one had said anything.

"A new student, after only two days?" Yaoyorozu asked from her desk at the back of the room.

"It's a foreign transfer student. She took the entrance exam at a sister facility in Italy and only just arrived in the country yesterday." Aizawa replied back idly.

A knock on the door had them all focusing in on it. Of course, in a school where there wasn't really anything like "mid year transfers", it was strange and attention catching for a student to pop into the class after the official start of the year. Especially since the hero course was just two classes that was suppose to be comprised of only twenty students. Whoever the transfer student was, they had to be some kind of impressive big wig to have the school changing things in order to add her to the hero course without removing anyone already there.

While the students thought this over, Aizawa answered the door, sticking his head out to talk to whoever it was on the other side. There was a short conversation before Aizawa turned back to face the class.

"Class, meet your new classmate...Leander Halyn."

The girl that walked into the classroom was, indeed, eye catching. She stood about five and a half feet tall, making her just a little under an inch taller than Midoriya. She was thin with curves of a woman much older, and very pretty. Her waist length hair was a pale blue, like that of frozen water and was worn in a half up, half down fashion that left her chin length bangs as the only hair around her face. Those bangs were parted to the right to hang over her right eye. Her face was slender with full lips pulled into a smile, a straight nose and wide eyes of a deep purple color.

She wore the school uniform with the tie loose, the first two buttons undone, the skirt on the shorter side, the shirt untucked and the blazer left open, and paired it with white, thigh-high stockings, black gloves, and black boots. Eyes, though just for a moment, instantly zeroed in on her skirt from under which sprouted a feline-like, pale blue tail with a furry tip. Over all, she was pretty and, despite the tail, looked like any none mutant-type human.

But it was the way in which she entered the class that made the students stare.

The girl walked into the class with a natural sway to her hips, her eyes directed straight ahead, her chin high, and her shoulders set straight. She walked like a girl who knew she was the hot gossip, her posture brimming with self confidence while her smiling expression suggested that she didn't notice, or care, that she had all eyes glued to her. She came to a stop beside Aizawa, one hip junting out while she grasped her bag with both hands behind her back.

"Leander comes to us from Rome and is new to Japan." Aizawa told them turning to the girl at his side. "Say something."

"It's a pleasure to meet you all. Please call me Halyn." she said politely, her accent rolling some of her letters. She bowed slightly to the class and gave them all a bright smile.

"Very good, now take your seat. You'll be sitting behind Todoroki." Aizawa told her.

"Yes sir." Halyn replied.

Halyn slipped between the desks, taking her seat at the very back of the classroom. As she sat, her tail curled around her waist, making sure that she didn't sit on it. Once she was seated and the class's attention had returned to Aizawa, class was started. The regular morning classes passed pretty much the same as they always did. Each teacher made it a point to call on the new student, testing to see what she knew.

The girl was pretty decent, though she excelled in foreign languages. Kind of fitting of someone who came from a country where today's youngsters spoke several different languages, including English. When afternoon classes rolled around and All Might took over for combat training, Halyn seemed just as thrilled about being able to put on her costume as any other student would be. When she came out to join the rest of the class, all eyes became glued on her.

After the debut of the R-rated Hero, Midnight, whose outfit had left little to the imagination, regulations on just how much skin could be revealed by a costume, had come into play. It only took one look at Halyn in her costume for them all to know one fact.

Halyn was flirting with the line between what was acceptable and what wasn't.

She came strolling out in nothing more than a strapless, bra-like top and high rise, panty-like bottoms, both in a royal blue, with a sleeveless, cropped, black hoodie worn over them. A black belt was strapped around her waist with knives, a pole of some sort, and pouches strapped to the back and belt like straps decorated each bicep. She had added fingerless, royal blue gloves, thigh-high silver stockings, and knee high boots that were nothing more than straps on the sides and back. To top it off, she had covered the top half of her face with a royal blue mask.

Despite the revealing nature of the outfit, she strolled out to join the rest of the class as if she had no issue with it at all, her tail swaying happily. Mineta had a field day upon seeing her, his eyes going wide. In fact, all of the boys turned to look at her as she joined them.

"Don't you think that's a little too..."

"Little?" Halyn asked, finishing Jiro's sentence for her.

"Yeah." Jiro confirmed.

"You know, without the hoodie, yeah, but I'm pretty comfortable in this and it falls within the limits of the costume regulations. Not to mention that, with my quirk, it has it's uses." Halyn replied.

Before anyone could begin to question her on what her quirk was, exactly, All Might approached

the class then, to explain what they would be doing for the class. Halyn, a grin on her face, jammed her hands into the pockets of her hoodie.

"Today we will be testing your ability to think on your feet against real life enemies in a game of Capture the Flag. You can go at it alone, or in teams of two or three. You will have the duration of the class to capture as many of your classmate's "flags" as you can. You will be graded on your performance as well as how many flags you manage to capture and lose." All Might explained to them.

It wasn't the most difficult objective they had been given in class, but it would be challenging. Especially when they were granted the permission to use their quirks in any way they could. Halyn's gears were already turning, her eyes scanning the mock city beyond them that would serve as their battlefield of sorts.

"Leander-chan!" Halyn perked up, her tail giving one idle flick, before she turned to see who had called her. Uraraka, with Midoriya behind her, approached Halyn, a smile on her face. "Would you like to team up with us?"

"Thanks for the offer, but I think I'll go at this alone. I want to be able to observe as well as participate, and that's difficult to do if I'm with a team." Halyn said honestly, not the least bit concerned with announcing her intentions.

She gave Uraraka and Midoriya a smile before turning back to look at the mock city. There were several high points, but also a lot of low points. Plenty of places to lie in wait and plenty of places to ambush from. She could definitely have a wide range of fun with this location as she got a feel for her classmates and their range of quirks. The thought put a smile on her face.

All Might passed out the "flags" they would be using, which was just basically tie-on headbands of a bright red. They were allowed to tie it anywhere on the body, but they had to use a certain knot that All Might showed them for tying it. To make it easier for others to take them. Halyn took hers and stared at it. Where on her body could she tie it that she would always be aware of it without having to consciously remind herself every second?

Then it hit her.

Halyn's tail gave a happy flick, but she was pulled from her thoughts when All Might announced that he was going to give them all ten minutes to find themselves a starting point. After those ten minutes, the race to snag other flags would begin. He called a start to the ten minute time limit and retreated to the observation room while they ran to find the perfect spot. Since the students had full rein to use their quirks, Recovery Girl was already waiting in the observation room. Even Aizawa was there, ready to observe the students and their progress.

A simple push of the button brought the many screens sprawled throughout the area, to life. From one angle or another, they could see almost every student in the class. A few, though, like Toru, were really well hidden, escaping sight from their fellow classmates, as well as their teachers. Among that number of well hidden students, was Halyn. The girl had already vanished among the city. All Might had already seen a bit of how the other students thought and worked, and was curious to see how Halyn handled herself.

When the ten minutes ran out, students started moving. It wasn't long before some of the faster and stronger members of the class, Bakugo and Todoroki among them, started snagging other flags, adding them to a slowly growing collection around their necks. After only ten minutes of play time, every member of the class came out of hiding, the mock city becoming a chaotic battleground.

Every member, but one.

Halyn.

No matter how many screens All Might studied, he could find no trace of Halyn. Wherever the girl had hidden, she had hidden well and hadn't come out yet. That, or she had a quirk similar to Toru's, which could work to her advantage in a game like this one.

Then he saw it.

It was just a brief flash of blue across the screen, heading right for Mineta and Sero, who were arguing and kicking up quite a racket. And then the two boys were on their faces, Halyn sitting on their backs. She snatched their flags and bolted, easily bouncing from one place to another until she was on the roof, then she was deftly jumping from roof to roof. It was as she was running away that All Might, Aizawa, and Recovery Girl finally saw where Halyn had tied her flags. Reaching behind her while her eyes continued to constantly search the area around her, Halyn tied the flags she had just stolen...to her tail.

"It's a clever idea." Recovery Girl commented. "Whether her tail is apart of her quirk or not, she would always subconsciously be aware of it and anyone or anything that could cause it harm or attack it."

"By tying the flags to the base of her tail, she is always constantly aware of them. Not to mention that some of the other students would be hesitant on reaching for the flags when they are that close to her backside." Aizawa said.

They watched the screen as Halyn dropped out of sight between two buildings. She reappeared a moment later, stealthily peeking out around a corner, her body low to the ground and her purple eyes constantly scanning the area while her tail flicked in anticipation behind her. In that moment, she managed to look like a cat that was out on a prowl. Then her eyes landed on their next target.

Kirishima.

A grin curled her face and, like a cat, her whole body froze on the spot, the bottom half of her body lifting just a little bit more into the air as she prepared to ambush him. Kirishima obviously didn't see her. He was scanning the area, but he, somehow, managed to over look Halyn. Which would be his undoing in this game. The moment his back was to her, Halyn's tail flick once, and then she was rocketing forward, like a pouncing cat.

Poor Kirishima went down before he even knew what hit him.

A yelp of surprise left him as Halyn hit him squarely, just below the shoulder blades. The suddenly addition of her weight was enough to send his body swaying forward and off its feet. Next thing Kirishima knew, he was face first on the ground, a foot on the back of his head, keeping him in place.

"Thank you~!" came a sing song voice before his flag was ripped from its place around his neck.

Then Halyn sprang off him, vanishing down a darken alley between two building before he could react. For the most part, every time Halyn came across someone she wanted to steal a flag from, it was the same kind of attack. She would lay in wait, watching patiently for her opening, and would attack swiftly and precisely, vanishing once more before her surprised opponent had the chance to counter-attack. Before the game had hit twenty-five minutes, Halyn had gathered a total of four flags, including her own.

Then she came across an opponent that would be more difficult to take by surprise. Halyn, who had managed to squeeze her generous figure in a space that was about a third her size, came across Todoroki as he was walking down a back street, his eyes constantly surveying his surroundings. Halyn watched him patiently, her eyes never leaving him. As she watched him, the top half of her body sank low to the ground, her tail curling over her back as she froze in the position.

It was only a brief window, not bigger than a breath, in which he turned his back to her, but Halyn took it, and took it swiftly. She exploded out from her hiding space and was already just inches behind him by the time Todoroki realized that someone was breathing down his neck. He whipped around, wide eyed in surprise, but Halyn had already hit him, taking him off his feet. She rolled with him as he hit the ground, and quickly sprang away from him as ice sprang to life from his right hand. Another jump carried her to the nearest rooftop.

Todoroki quickly got to his feet, rounding on the roof top, but Halyn was already sprinting away...carrying two of his flags with her. It was in that flight that Halyn finally drew attention to herself and it was attention she would have been better not drawing.

Halyn had just jumped across a gap between two roofs when, out of the side of her eyes, she became alerted to a fast approaching opponent from her right. She landed, but instead of running, her knees bent a little further and she waited a breath until a hand was reaching for her face. Then she sprang directly into the air, the strength of her legs rocketing her a good twenty feet up. Looking down, she looked into the surprised face of Bakugo.

Surprise quickly turned to annoyance, as he twisted to change directions. It was in that moment that Halyn reached back, pulling a blade off the back of her belt. She gave a yank, the sunlight catching on the wire attached to the end of the blade, before she threw it, the blade burying itself deep into the side of a taller building across the street. Thinking she had screwed up or something, with a blast from his left palm, he sent himself rocketing towards her.

Halyn had other plans. She gave a yank on the wire connected to the knife and a whirling noise reached Bakugo's ears before some kind of mechanism in her belt, started reeling the wire back in, yanking Halyn out of Bakugo's way and towards the building she had thrown the knife at. Halyn hit the building feet first, kicking off to swing herself up and onto the roof. Another pull of the wire and the knife came free, Halyn catching it.

Bakugo wasn't giving up that easily. He had five flags and Halyn had six of the remaining sixteen. He had been following Todoroki up until she had attacked him and taken two of his flags. With those two missing, Todoroki had been reduced to just one. That left nine more somewhere in play, but, at the moment, Bakugo was sure that Halyn had the most.

Halyn wasn't going to let herself be captured so easily. Especially when Todoroki joined the fray, seeking to reclaim the flags she had stolen from him.

Both of the boys landed on the roof with her in their pursuit of her flags. Halyn's head whipped back and forth as she, herself, took in the two boys now facing her. Instead of expressing concern, though, a grin curled her lips. She jumped into the air, to avoid Todoroki's ice, and another throw of the knife and yank of the wire, pulled her up to the next roof and out of the way of Bakugo's attack. The two boys followed her, Halyn remaining crouched, her eyes intent on the two in front of her.

"She's very clever." Recovery Girl remarked as they watched the screens.

"She's nimble and patient. Not impatient and rash like young Bakugo." All Might agreed.

"But what is her quirk?" Aizawa mused.

"It doesn't say in her file?" All Might asked.

"No. I have her results from her entrance exam, but even in that, she didn't noticeably use a quirk. Though, notes from the exam judges said that she was out of sight for most of the exam. The only time they caught sight of her was when she finally attacked." Aizawa replied.

"Didn't she have official recommendations?" Recovery Girl asked.

"She did?" All Might asked.

"Yeah. Her parents were both well known heroes in her home country. The best team the country ever saw. Not to mention, she excelled all through middle school, but she chose to take the exam, to get in under her own power rather than by the recommandations of someone else." Aizawa answered.

It was a bit naive, but it was honorable as well. Aizawa could see and appreciate that. When he had read Halyn's file, he had been mildly impressed and intrigued. The girl had been the top of her grade since fourth grade. Before that, her scores, rather it was academically or athletically, had been sub-par, at best. Whatever had changed between third and fourth grade, Halyn had preformed a completely one-eighty, her grades improving and her potential as a hero, sky rocketing.

Now, he was watching as she dodged and avoided two people with confidence in every step she took. And it seemed that she was well aware that it took hard work to make it. Now the question they all had was...what the hell was her quirk?

Back out in the mock city, Halyn's eyes shifted from one boy to the other, her tail flicking idly. Bakugo looked...well, pissed off. His face was twisted in his annoyance. It was a shame really. Halyn was sure he would be good looking guy if he would relax and smile genuinely. At the moment, though, he was all eyes for her, a growl rumbling from his chest.

Todoroki, on the other hand, was watching the both of them. He wasn't going to relax his guard around Bakugo just because the explosive teenager was focused more on Halyn. Halyn's eyes scanned both, her mind working through one idea after another.

If she could get one to attack her, then, for a brief moment, the other would focus on him and not her. That would give her the opening she would need to avoid the attacker and escape the other. All she needed was a few seconds' head start and she would be good.

Now, which one could she provoke?

Duh!

Halyn turned her focus to Bakugo. She knew his type, was aware of what she could do to set him off, and all without saying a single word to him. So, she waited until his eyes met hers...and she grinned, her tail curling playfully. Bakugo twitched, his face twisting just a bit more. With one eye fixed on him, Halyn raised a hand and covered a fake yawn. It was as if she was saying that both of them were too boring to bother with.

And just like that, just as she planned, Bakugo exploded, launching himself at her. He roared in fury, ticked off with just that simple gesture.

But Halyn miscalculated.

Bakugo wasn't the only one to attack her.

Just as Bakugo attacked her, so did Todoroki. Halyn's eyes widened in surprise, but the grin on her face only grew.

This was even better than she planned!

Just as they were about to reach striking range of Halyn, she jumped. She sprang easily into the air, clearing their heads as they reached her. She landed deftly on Bakugo's shoulders and used him like a diving board to spring forward, knocking him into Todoroki. The two rolled apart when they hit the ground.

By the time they got their balance back and turned to look at her, Halyn was already three streets over, vanishing over the side of a roof top and carrying with her two of Bakugo's flags.

In the end, when time was called, Halyn came out the winner with eleven of the twenty-one flags tied to her tail. She stood in front of All Might as he pat her on the head with praise. Though she acted like it was nothing, the happy swaying of her tail betrayed her true feelings while waving the eleven flags in victory. The girls also sang their praises to Halyn who waved it away as if slightly embarrassed.

"I saw your stand off with Bakugo and Todoroki. That was so clever, getting them to attack you so you could jump over their heads and escape with two of Bakugo's flags." Uraraka said.

"Todoroki is the one with two hair colors, right?" Halyn asked.

"Yeah."

"Well, to be honest...I honestly didn't think he would attack, too. I originally had a completely different plan in mind." Halyn admitted.

Todoroki and Bakugo turned to look at her from where they stood a little ways away from her. Halyn was smiling sheepishly back at the girl, her tail curling.

"Seriously!? What was the original plan?" Jiro asked.

"Well, I had only intended to provoke one of them into attacking. Bakugo seemed like the one with a bigger sense of pride, so I was actually only aiming to prick his pride. I didn't take Todoroki as the type to easily have his pride wounded, so it kind of surprised me. Though, honestly, he's human, so I guess it makes sense that I kind of insulted him." Halyn remarked, sheepishly scratching one cheek as she smiled.

"And you went the whole time without using your quirk?" Yaoyorozu asked.

"All of my brothers are pro heroes and they've taught me that you can't always rely on your quirk. I've been trained in hand-to-hand combat since I was about eight years old, so now it's second nature to just resort to that over my quirk." Halyn replied.

Before anyone could start asking what her quirk was, All Might dismissed the class, and the girls split off from the boys to go to their locker room to change. Halyn was able to avoid all questions about her quirk after that.

In the end, she was able to escape school for the day without anyone ever finding out.
