Ok, this is my first attempt of a fic based in the To Aru series, this is basically an idea I was having for a while and wanted to write it and let others see and judge it, the English is not my mother language so if there is any grammatical error or something else, please tell me and I'll try to correct it quickly. I hope everyone has enjoyed the story so far. I definitely have fun writing it.

"Such misfortuneeeeeeeeeeee!"

A boy of about sixteen years old with spikey black hair slid down the side of the bank, landing on the flat portion and started running. His head was bandaged, he also had a bandaid on his left cheek and if you looked closely, you'll notice some layers of bandages under the shirt. That boy, Kamijou Touma, a level 0, Imagine Breaker, he had came back from a fight with evil magicians, he was seriously injured and nearly cost him his life. Luckily, Heaven Canceler treated promptly, so Touma escaped from death

But after that, he had a huge problem facing him.

Everyone, who met Touma, knew that he was a brave boy. He didn't frighten enemies, although it was the number one of Academy City or who had power that could killed him and destroyed the world, they never make him falter.

However, he was still scared of a person.

"Get back here! You idiot!"

A bolt of lightning shot out from just over the bank and hit the ground in front of him. Shortly after, a girl of about fourteen years old slid down the bank as well, seemingly chasing after the boy. That girl was a one of strongest espers, #3 level 5, the Electromaster, Railgun, Misaka Mikoto.

"Oh come on, Biribiri! I just got discharged from the hospital last week!" The boy shouted as he turned to face his pursuer.

"It's your fault, why you always doing such an dangerous things!? Do you know how much people was worried about you!? "said Mikoto while sending an mass of electricity to Touma.

"I'm so sorry, Mikoto-"

"You know, I'm always worried about you…" Mikoto hugged Touma and a bit of tears came out from Mikoto eyes. "After all, I'm your girlfriend, I could share your burdens."

"Mikoto-chan..."

Yes, he was her boyfriend. It had been about 5 months since they first began seeing each other as more than friends, a fleeting amount of romantic feelings had entered their relationship. After 2 months since he became her boyfriend, Touma missed in 3 months. During those months, Mikoto didn't eat and sleep easily, she would always cry whenever she thought about him, her fear of losing him caused her not to stop concerning about him. Until that day, when she knew that he came back, she was so glad but she was also worried when she saw his serious wounds in his body, her heart stopped beating when the doctor said that he nearly died. She could just sigh of relief when she knew he was alright but her anger for him got worse, she attacked him because of his reckless and stupid action.

Touma got silent a little time and then he stroked Mikoto head, which caused her to blush.

"I'm so sorry, Mikoto-chan. I was wrong when I left without saying anything, it's just that I don't want to make everyone concern and I also don't want anybody to be hurt." Touma said guiltily.

"You idiot, you're my boyfriend. You think I could stay here without worrying, it seemed that I spent three months in the hell."

"Ok ok. I'm wrong. What about walking and shopping together in Seventh Mist?" Touma said softly.

"Sure." Mikoto answered, wiping the tears from her eyes. "But your treat, you caused me to be in hell in 3 months, so you had to make it up to me."

"Nah, it's harsh." Touma groaned but he still smiled

"By the way..." The Electromaster's face got serious. "Just promise me."

Touma gave her a curious look, confused by her expression.

"You will never leave my side, I don't want you to leave and you got yourself into dangerous situation." She said seriously.

"Right right, I won't left without telling to you. I won't be reckless and careless and caused you to concern about me. Ok, my Tsundere girl?" He joked and rub her head.

Misaka looked at him, a pure of innocence and happiness, adorned with genuine expression was shown by her face. She smiled softly, she was grateful for what the spiky haired guy had said. He was Kamijou Touma, a level 0 but that level 0 could take her heart, he was the most important person of Mikoto, he was her life and he was also her idiot.

In a building deep under the ground, Academy City.

The laboratory, number 730, a research-facilities of a famous pharmaceutical company in Academy City. In there, there are hundreds of experiment, scientific researchs performed, talent scientists gathered together. In addition, not much was known about that lab, it was a secret lab, it covered in thicked walls of steel, thicked doors of steel. Hardly anybody knew about its existence, the security system was a one of the best ones in the world, it could hardly disabled, there are hundreds of cameras were mounted and thealert system would active if there were strangers broke into the bulding, guaranting the total security of people at the lab.

"Good morning Dr. Fusui."

A young woman in a lab coat around her 25's with long hair tied into a tight bun walked into a lab room.

"Good morning Dr. Hikari" The man with black hair, about 30, said friendly.

"How are the experiment coming along?"

"The hosts are excellent vessels for the delivery of the virus, and I think we can begin to move on to a clinical test" Dr. Akira said excitedly.

However, Dr. Hikari seemed not to be happy, in fact, she was worried. That research, it was a weird study...no, it had to be a crazy one. Dr. Hikari her full name was Hikari Yuki, she was the talent and youngest scientist, she had come to that lab for 5 years. For Yuki, scientific research was her great passion, she always dedicated herself in every project, when she completed a one, she was so happy, excited, it felt like that she created something which was new, helpful and even it could be huge contribution for the scientific community and mankind.

But now...

She didn't see like that as before...

She didn't see her excited and interested expression show on her face.

Instead,

She feared it.

She was so scared it. That research, that project, which was assigned to her and that guy, Dr. Fusui, his full name was Fusui Akira, a mysterious scientist. Yuki didn't know much about his background, she just met him when she took over the project and she would be his main partner, researching that project together. During the 2 years, she just saw that Akira was very intelligent, a expert scientist, he had a plenty of knowledge, from basic ones to advanced ones, he set up various experiments and conducted them, his dedications for company was great, his react and influence was so big.

"Dr. Hikari, what's wrong? Why do you make this expression? Don't you see that we nearly success? Cheer up my partner, when the project was completed we could created a greatest invention about overcome the greatest enemy." Akira said excitedly.

"I know. But Dr. Fusui, the project, are you sure that it will be alright? I mean...that thing, it's always believed to not exist and in the history, a lot of people found, research so hard, they required a lot of time and energy, even they cost them their future, happiness and life for it but results was zero, they couldn't stop that, it still come to them, it wasn't against the order of nature which anybody must face sooner or later." Yuki said sternly. Yes, a crazy experiment, it was not possible that thing could existed!

But Akira seemed not to be furious because of her words. Thus, he had a good laugh, his laugh could be seen that he didn't mean to mock her, it was just a laugh, Yuki didn't really understand that person.

"Your words was essentially correct, Dr. Hikari. I don't deny that a lot of people pursued it and they failed, even it cost them their most precious things and it could their life. Everyone considered them poor persons, wizards, psychopaths, etc... and denied all their writings, researches." Akira said calmly.

"If so, why do you-"

"But..." Akira interrupted. "It's trivial thoughts, Yuki-san. Trivial ones of ignorant, jerk, stupid persons and they don't deserve attention. We can just accomplished great achievement if we have faith and do our best. The proof is this project, it's nearly completed and all I need a test subject now.

"I see." Yuki sighed "So what do you want to choose? Monkeys? Rabbits? Or lad rats?"

"Oh no no no." Akira smiled "Animal tests is never helpful completely. It's just about 70-80% and this research, I don't want any mistakes to happen though it's the smallest, it's so important. So I'm not going to use animals. Instead, I'm going to test them on humans.

"What!?" Yuki yelled " Doctor please tell me that you're kidding."

"Oh, I'm not kidding, Yuki-san. You saw, right? Human is always the greatest sample, results was received from human experimentations, which was so exacted and and perfect."

"But you fully know that it's illegal and inhuman. If somebody die during the experiment, consequences to us will be extremely severe, think about it, Dr. Fusui!"

Yuki said with a stern expression. She didn't like experiments on humans, they was so cruel, merciless and inhuman even though they was really far more effective than animal tests. But many unprinciple scientists disregarded the negative side, they didn't care the mortality of others and acted coolly, they was no more than monsters and she didn't want her colleague to be like that, no anymore.

But replying her, he laughed loudly.

A evil laughed.

"It seems that you're so young that you can understand the real science. Ahahahaha."

The young girl pissed off because of his attitude but she was silent. She wanted to know what that man was going to say her.

"Yuki-san, it's for that reasons the science failed miserably in a lot of important researchs. It's for that reason many excellent researchers frittered their talent on little things and it's just for that reason that old-man refused me!" Akira said angrily "I'm going to show him this project, my succcess and he will be regret at discounting me, discounting his son."

Then he took the record on the table. He smiled evilly.

"And this's the person whom I chose for the experiment." He looked at the file, especially the picture, the picture of a certain spiky haired boy.

In somewhere, Academy City.

In a dark alleyway, a person stood on one leg with my back to a wall, their hand held cell phones to their ears . Looking closer, that was a blonde haired boy, sun glasses and he wore a certain highschool's uniform. He was a spy, a esper-magician hybrid, magic name Fallere825 and Kamijou Touma's friend, Tsuchimikado Motoharu.

"I see. So he finished it. What he's going to do next?"

"..."

"What? Are you sure?"

"..."

"Oh man. That man is really crazy. But it's natural in that city, many cruel experiments happened, even victims are children."

"..."

"Ok ok, I know I have to do. So who is that?"

"..."

"What the hell!? Don't joke right now!How could it be him!?"

"..."

"F*ck! That bastard! He should see himself to be so lucky! If I find him, I won't forgive him!"

"..."

"I'm being very patient. So...are you okay? No one is around you?"

"..."

"Of course. It's my work and I don't think that he could make it easy. He had the girlfriend who loves him more than anybody."

"..."

"Oh, his girlfriend is Railgun. You know, no doubt that she will become so scary when someone dares harm him. In addition, after his missing, she's usually with him and rarely leaves his side, it's so difficult to do anything him, at least in this moment."

"..."

"Don't worry, he's my best friend so I will also do anything to protect him...as he always helped me and everybody."

"..."

"Ok, so I hang up, you should go back before he suspects you."

"..."

"I know that I will do, so don't worry about me. See you later."

Motoharu hung up and sighed. He was thinking, thinking about his friend and in fact, his best friend. Motoharu chuckled to himself, a spy has a best friend, there was surely a humorous thing when he was a trickster and liar by his own admission, willing to betray anyone if it helped him, his enemies who wanted to kill him was surely too many to count.

"Kami-yan, you own me again, my friend."

OK, here you go my first chapter of this fic and I'm already exhausted, hope the next ones don't become so tiresome and extended, well see you next time.
