Chapter 1

Rose stared uncaringly at the hole made of multi-colored lights, she didn't know how long she had been falling inside but she had grown bored after the first five minutes.

At first, she had wondered how she had gotten there but then remembered that she had just died.

All she had done was go to a local convenience store to buy salsa for chips. Her brother, Jon, was waiting at home so that they could watch a movie together. It was movie night, a tradition they had kept since middle school.

She had been at the checkout counter, when she heard a small TV announce the winning lottery numbers. At first she thought she heard wrong, because they had said all of her lucky numbers, she always bought the same ones, for every game. Looking at the screen she was shocked to see all of her numbers there, and then she remembered that she had bought a ticket just that morning.

Taking her purchase, she hightailed it out of there, she couldn't believe it, she had won the lottery.

She ran down the street, she needed to go home and find the ticket as soon as possible. She crossed the street making sure the light was green first, but before she could even take her first step, a car ran past the red light, and swiveled off the road. It hit her, going at 40 miles and hour, and pinned her against the traffic lights.

She didn't even have a chance to scream, she died instantly, without pain or suffering, and then woke up to her falling into a tunnel of lights.

"God, I wish Jon was here," she said out loud.

POP!

"What the?"

"Jon!"

"Rose! How did you get here? Where is here?"

"You will never believe this but I died in a car crash as I was heading back.."

"Oh shit. Really. I'm sorry to hear that."

"It's okay, it was actually pretty painless, over in a second. How did you die?"

"I choked on a chip."

"What?"

"Well after you left, I waited for a bit, but you took too long and I started to eat the chips. Then I heard the news announce the lottery numbers and remembered that you bought a ticket today. I was so shocked that you actually won that I choked on a chip, and it looks like I finally died."

"Ouch. Was it quick at least?" she asked curiously.

"Nope. I was choking for like ten minutes before I blacked out. Then I appeared here. Not going to lie, this was not what I was expecting the afterlife to be."

"I'll say. I was expecting white fluffy clouds and a quire of angels."

"I was expecting fire and brimstone, with a mob of devils carrying pointy spears."

Jess then noticed something, "Hey look. There are glowing crystals over there."

Jon looked and saw that a little distance away there was some glowing hand-sized white crystal falling with them. "Let's grab one and see what it does."

They grabbed one each, but as soon as they did they were engulfed in a blinding light.

(Time skip)

After they had grasped the crystals, they had experienced what it felt like to be reborn, and that was not a pleasant memory. They had been reborn into a pair of twins, Jun and Mio Shimizu. After learning that Buddhas where in fact right about the whole reincarnation, they received their next shock. They had been reborn into an anime show that they used to watch, My Hero Academia.

They were born into a normal family, normal by their standards anyway. Their mother worked as a hairstylist, her quirk gave her the ability to manipulate hair to a small extent, while their father had short range telekinesis, although he never got to use it often seeing as he worked as an advertisement agent.

Yep they were a normal run of the mill family to many, the only thing that was strange was that unlike their parents, Jun and Mio had received exceptionally powerful quirks.

They had been four when they had discovered their quirks. It had started off as any normal day, their father had taken them to the park while their mother worked, and they were running around playing tag. Jun had been a bit to forceful and had pushed Mio a little to hard. She had scrapped her knee, and in her anger had hit Jun back. Jun had unfortunately flown back several feet away with a broken arm.

They had taken Jon to the hospital after that and Mio was tested to see what kind of quirk she had, after several hours they had determined that her quirk allowed her to control things she came in contact with, tactile telekinesis in other words. Mio was so excited that she punched a hole in the hospital wall by mistake.

During his stay, Jun had also discovered his own quirk. The doctors where shocked when they found him the next day with a completely healed arm. They had at first thought that he had gained a healing ability, and they were half right. What his quirk actual did was give him complete control of all things biological. They had tested him and found out that he needed direct contact with the thing in question.

In a sense they had both copied their parents, Jun had gotten his bio-kinesis from his mother, while Mio had gotten her tactile telekinesis from her father.

Mio had always admired All Might, her room was decked out in All Might merchandise, so logically she wanted to become a Hero. Jun on the other hand did not have such aspirations, he wanted to become an inspiring doctor, something that he could truly use his powers to the fullest. They both worked hard for their dreams, Mio would lift weights and exercise any moment she had free time, and her brother would pour over texts concerning biology. Mio took martial arts classes and Jun took to studying animal anatomy. Mio started to manipulate her force field and Jun began to modify his body.

In no time at all, time had passed and they both changed much, they were now both fifteen. Jun and Mio stood in a rocky wasteland, facing each other, both having determined faces. They both had dark black hair, light skin, and blue eyes. Jun stood at five feet seven inches, had a waist length ponytail, and was only dressed in pants. Mio on the other hand had shoulder length hair and wore black body armor on most of her body, a mask and goggles covering her face.

"I'm going to UA soon," she said as she manipulated her personal force field to lift herself a few feet off the ground.

Jun stretched a bit before he used his quirk to grow and sharpen his nails, "I wish you luck sister, I hope you won't cause to much trouble. I wish I could join you, but I have to take a worldwide tour in a few hours. They have been begging me to go heal people for months now, and I can't say no any longer."

"That's a shame," Mio said dejectedly, even though on the inside she felt ecstatic about the news.

"You are a terrible liar. That's why before I leave we will have one last match. What the score again?" he said as his hair began harden and move as if it had a mind of its own.

"… Lucky me. The score is 507-3, in your favor," she said grudgingly. The reason why she covered most of her skin, was because Jun only needed the briefest of contact with her skin to manipulate her body, usually by disabling her nervous system, or knocking her out instantly. There was even one instant where she had made him especially mad and he had blinded her and made her deaf. Of course he had always fixed her back to tip top shape, he was the worlds leading healer after all, but the fear was always there.

"Ready when you ar-" the shirtless boy didn't have time to finish when his sister came barreling towards, a fist pulled back aiming at his exposed chest. Despite how fast she was going, the dozens of modifications Jun had made to his body allowed him to easily see the attack coming. He rearranges the muscles in his arms and legs to have the explosive power of that of the pistol shrimp, that was capable of throwing supersonic punches in the water.

He jumped into the attack and ducked under it before hitting her with a supersonic uppercut to the abdomen. Her shield took most of the force, but she was still launched backwards. He didn't give her a chance however as he leaped at her recovering form ready for a downward kick.

Luckily, she was able to perform a backwards flip and get out of range, before she took to the sky, the only advantage she currently had was her ability to fly. While she was more durable and stronger than him, she wasn't as fast, nor did she have the ability to heal herself mid battle.

Jun however prepared for such an outcome, sucking in breath of air, he exhaled a cloud of gas, not only did it block out the ground but anyone that inhaled it would immediately start to hallucinate. Mio couldn't see him on account of the gas cloud, but Jun didn't have such a problem, he used his quirk to modify his eyes to be able to see infrared and his ears to be able to hear like a bat.

'Shit, where did he go?' she thought worried when she lost sight of him. Knowing better than to just stand in one place, she began to fly around in an unpredictable pattern. She then felt something hit one of her metal plates, there half way impeded into her armor was a what looked like a sharpened bone, the tip was leaking some type of liquid, 'Damn, he is taking out the poisons this early on.'

She began to dodge as more bone projectiles began to fly at her from the cloud. With no other choice she began to fly in a circle faster and faster, creating a whirlwind of air, trying to disperse the cloud.

Jun with his palm extended in her direction shot one last bone projectile, it came out of the hole in his hand which he closed a second later. He returned his eyes and ears back to normal, since they would just be hindrances at this point. She landed on the ground with a boom.

"Super hero landing, your getting better," he briefly commented, as he sprinted towards her.

She stood up and blocked the punch with her armguard before returning the favor with a kick to the ribs. He jumped into the air, and spun, aiming a spin kick at her head. She leaned backwards letting the kick sail past her, and aimed a low kick at his falling form.

'She's getting faster,' Jun thought as he manipulated his hair to harden and cover the spot that he was going to be hit. The kick connected and he was launched away, skidding on the earth.

"Now my chance," she exclaimed as he flew straight at him, and grabbed on of his legs with her gloves. She then slammed him against the floor multiple times, like a twisted game of wack-a-mole, then grabbed his head in her hand and proceeded to drag him against the ground at high speeds. He tried to brake the hold, but Mio would just slam him through another boulder. She knew that she couldn't give him a chance to breath, or else she would end up losing again.

See finished her assault by driving him head first into a large rock formation.

She stood ready for an assault, sure that that wasn't enough to take him out. And sure enough, it wasn't because he burst out of the rock a second later. The only damage he had gotten was a split lip and a couple of scratches. 'It's a good thing I placed a layer of woven spider silk underneath my skin and reinforced my bones to near diamond hardness. Still that kick, did fracture some of my leg bone.' He healed the damage in an instant.

"That was a good attack Mio," he said as he walked closer to her.

She tried to fly away but was unable to, her body from the neck down was frozen. "What? When did you?"

All he did was grip a lock of hair and showed it to her, she traced the strand from his hand all the way to her neck, where it went under her armor.

All Jun needed to control something biological, was have some part of him connect to the thing in question. It didn't matter if it was a hand, a finger, even a strand of hair, only that his cells were touching what he wanted to modify.

"Not bad, but you lost focus once you were attacking," he commented, connecting back her nervous system.

She cursed herself, she should have known to watch out for his hair. The real reason why his hair was so long wasn't for looks, at a moments notice he could modify it to suit his needs, like turning it into a shield, spikes, or even modify each hair into those of jellyfish stingers. His entire body could be classified as one giant weapon, the only reason why he didn't want to be a hero was because his dream had always been to be a doctor.

Unlike Mio who was barely starting off her career, Jun had already finished his education, and was a certified Doctor for many years now, something that was extremely easy when he could scan the bodies of others and fix their problems before others even had the chance to take out their stethoscope. He was actually quite the celebrity, appearing in guest shows and other media outlets, usually healing someone from cancer, fixing blindness, or some other else.

The entire battle had only lasted for two minutes, even though usually it would take much longer. Their weekly spar would be a chance to experiment with their powers and grow stronger, but this time Jun was pressed for time.

Just then a black helicopter appeared in the sky.

"Looks like my ride is here, I wish you luck Mio, and please behave, I would hate to get a letter saying you got in trouble again," he said as he gave her one last quick hug and boarded the helicopter, people inside already having a change of clothes waiting for him.

Mio looked at her brother leave, fresh tears sprung from her eyes, "… Free. I'm finally free."

The smile on her face refused to leave. She was happy, no longer did she have to hold back her thoughts for fear of angering her brother. She wouldn't have to watch over her shoulder every time Jun was in a foul mood. She still remembered the time that she had eaten his share of a cake and awoke the next day with her legs backwards. He had a sadistic side a mile wide, and some of his pranks ranged on the border of cruel.

"I need to go celebrate right away! OMG, I can finally start wearing short and skirts again," she shouted as she took off into the air and flew straight home.

However, on her way home, she spotted Tai, a boy her age that used to pick on her when she was younger. He would usually pick on her when Jun was there, knowing that he was the one holding her back. Grinning to herself she headed in his direction.

She continued her way home, not paying attention to the crying boy, that was hanging from a tree by the elastic of his underwear.

She had free rein of the neighborhood now that her brother was gone. Anyone that had ever annoyed her was now free game. "Mawhahahahahaha…"

(Scene change)

As she laid down on her couch, flipping the channel on the tv every so often. She happened to stop at a news station, the woman on the tv saying something that caught her attention.

In recent news, today a sludge villian was stopped today, thanks to everyone's favorite hero All Might. This is the first sighting we have had of the famed hero, after being out of the limelight. Critics are divided, some question the reason for his reclusive nature. Are the rumors of him secretly fostering a child have some truth to them? More on this, later in the show."

Mio stared at the tv, there was a light whisper in the back of her head saying that this should be important, but she couldn't remember.

"More on the news, earlier today, Jun Shizumi, what many call the Doctor, started his worldwide pilgrimage to heal those that are unfortunate enough to not have the means for proper healthcare. I have already received word that many are traveling miles away from their homes just to be healed by what many call the world's greatest doctor, for free. His first stop will be on the District of Kamagasaki, where he will be curing many terminally ill patients, that lack the money for such treatments. We advise those that plan to be healed to check on the dates and location for when he will in your area. We here at channel 8 news wish him luck on his journey."

She turned off the news, the last thing she wanted was to be reminded of her brother right now. It was bad enough that her mother and father had yet to get over his departure.

She didn't need have much time to relax however, seeing as someone began knocking loudly at their door. Mio grunted as she flew towards the entrance, now that Jun was gone, she could use her powers inside the house again.

Opening the door she was greeted with the sight of a pretty girl, she had waist length indigo hair and was dressed in warm clothes, contrary to Mio who only had shorts and a tank top, on account of her force field keeping her warm.

"Aoi Yamada," she grunted in reply.

Aoi Yamada was a rising pop idol that already had a huge fanbase, on account of her good looks and perfect personality. The reason why Mio knew her however was because she had known her before her transformation. When they were younger, Mio used to bully Aoi for being short and fat, while Jun was busy taking extra classes.

However, it didn't take long for news to reach his ears, and after he punished his sister for her actions, he offered to change her appearance, as an apology. She had always had a low self-esteem, so of course she agreed. It took only a few minutes but once he was done, Aoi now sported perfect skin, perfect hair, perfect teeth, and a perfect figure. That had also been the moment where her crush on Jun began.

After her transformation she became more confident in herself and decided to follow her dream of being a famous singer. Her quirk, which gave her the power to make anyone instantly happy upon hearing her voice, only help her further her career.

She was slightly panting from running all the way from her house, a couple of blocks away, to Mio's home. "Is it true!? Did Jun already leave!?" She asked desperately.

"Yep."

"Ack!" She crumbled to the floor, she was devastated to know that she had missed her chance to give her farewells to her long-time crush. She started muttering to herself as she drew tiny circles on the ground.

Mio only glanced at her for moment, before slamming the door in her face and floating back to the couch, 'Walking is a lesser man's job.'

She ignored the constant banging from the door as she turned on the TV again and open a can of soda.

A/N:

So I'm a huge fan of My Hero Academia so I decided to write a fanfic about it. So one of the reasons that Mio doesn't remember why the Sludge Villain is important is because 15 years has passed since she was reincarnated. Also since both Jun and Mio didn't know at what time in the anime they were born into they couldn't do much about it so they slowly forgot.

A short explanation to Superboy's power, it's a telekinetic force field that surrounds his body and granted him abilities that approximated some of Superman's powers such as super strength, flight and invulnerability.

As for Jun biokinesis is the ability to control and change ones genes (DNA) by just using the psychic powers of mind however in Jun's case he has to have contact with the person or thing to change them.
