(This One Shot will also contain UshiTen and IwaOi (maybe other ships too I don't know yet ^-^') and this story takes place in the future. Well, everything is quite the same, but  the technology is more sophisticated and pills exists, which can extend your life expectancy^^)

"So, starting today, each of you will be assigned to a paid internship. I will screen you the list with the professors you have been allocated to on the Holographor. Please but your thumb on the touchscreen of your HoloX, your fingerprint will be registered and your allocated professor will be shown on the screen. The internship will start tomorrow. But you can already visit them today, if their praxis is open."
As the holography showed the picture and name of the black haired, he put his thumb excitedly on the screen, looking at it. I hope I'll have an awesome professor! I'm definitely gonna visit him today!
Finally, his allocated professor was shown on the screen.

"Satori Tendou..."

He mumbled to himself, somehow the name sounded familiar to him. "What? You got the guess monster?" Someone said from behind him. Guess Monster?
Kageyama turned around, facing a tall boy, who was wearing his long hair in a bun.
When the man saw that Kageyama didn't understand, he sighed a bit and explained.
"He's called like that, because he only guesses the perpetrator in his cases, without really psychoanalysing or interrogating him. The scary thing is, his guesses are 98% right. He's really a monster. Some rumors say he has a hidden laboratory, where he conducts some weird inhuman experiments..."
The tall man started to tremble in fear and the black haired got goosebumps. "He even looks like a criminal himself! Watch out kid..."
Kageyama remembered now, where he heard the name before.
Prof. Dr. Satori was in many interviews and was called the world's greatest psychoanalysist. But he was also called the guess monster, because of his creepy appearance and guessing accuracy.
"Asahi, stop scaring him! Satori-hakase is a great psychoanalysist after all. Let's go, Nishinoya is waiting for us." (Little writer's note: -hasake is the japanese honorific for Doctor/Dr.)
A silver haired man said, taking Asahi's arm and pulling him outside the auditorium. A brown haired guy followed them, rolling his eyes annoyed.
Kageyama sighed relived when he was finally alone. He stood up, wrapped up his HoloX and ScreenTab and went outside. He thought about his professor, hesitated a bit.

He even looks like a criminal! Watch out kid...

Kageyama shook his head a bit, went to his motorcycle and against his bad feeling, drove to the praxis.

He was really nervous as he went to the door. The black haired had to think of the tall man's words again, about the professor and the things he already read about him.
Is he really doing those inhuman experiment? What is he like? Will I learn something from him?
Kageyama took a deep breath, searching for a hand-eye scanner and camera, but their was only a plain door bell. Huh..?
He slowly pressed the bell, reading the sign on the door. No Holographor? Only a normal sign?

Prof. Dr. Tendou Satori, psychoanalysist and neurologist, forensic (science) laboratory

As the door opened, a young man with fawn hair, which had dark ends stood in front of him. He smiled slightly.
"Hello, my name is Semi Eita. How can I help you?"
Kageyama felt uneasy when he heard him speaking, but he did not know why though. His guts just told him.
"Ah yes, my name is Kageyama Tobio, I'm going to the University of psychiatry and neurology in Tokyo. I'm Satori-hakase's intern and kouhai for a year. Thanks in advance!"
The black haired bowed politely, he was just too nervous.
"It's for you Tendou-sama and it's only a student, you don't have to hide." Semi said and went back inside the building.
Kageyama rose an eyebrow in confusion, but did not move a muscle, as he did not know what else to do. Moreover, he feared what to do next.
After a short while a red and spiky shock of hair peaked over the door frame and suddenly, two big red glinting eyes looked at the black haired.
They did not blinked once. It sent Kageyama shivers down his spine. He felt, as if the glittering red would see directly through him, furthermore right inside his soul.

"What's the left hemisphere for?"

He asked slowly, still not blinking.
Kageyama gulped once.
"Uh... I-It's in charge of carrying out logic and exact mathematics and additionally processing, what we hear and handle most of the duties of speaking...?"
The guess monster squinted his atrocious eyes.

"Is this a question or an answer?"

"A-An answer, sir!"
Kageyama said a bit hasty, standing as straight as a pole.
"Who was John Wayne Gacy?" Kageyama was a bit nervous. Crap, I'm not good with the American's.

"Uhm... He was a famous US-American serial killer..."
He did not know more about him. Suddenly he heard a small snicker, which changed into a loud laugh.
The professor came from behind the door. He had his hands in his gown's pockets ans went with a stoop and gawky steps towards his new student.

"Great creator of the world, who is called God, who people think he really exists, we have a young intelligent handsome man in our team now!" He smirked as he walked around his new kouhai and quietly smelled him.
The black haired stopped dead in his tracks, his heart beating faster. "Mhm... Then let's go inside, I'll show you around."
The red haired went inside the building, followed by Kageyama, who slowly managed to calm down and look around interested. Semi was sitting in a office chair, typing something in a computer. A computer? They still exist?
On the wall hung several old looking lamps and pictures, which showed some tangled up lines or random dots. The whole interior design was old fashioned.
"Oh where are my manners, I'm Professor Doctor Tendou Satori, but just call me the almighty liberator." Tendou said proudly while opening the door to his office with a key.
Not even a ScanPad for his office...

He sat down on his office chair, gesturing his student to also take a seat.
Kageyama wasn't sure if he should speak or call him by the earlier mentioned name rather than calling him professor or Doctor Satori.
"So... Tell me, what are your goals?"
Tendou folded his hands and rested his chin on them, glaring Kageyama deep through his eyes.
Kageyama breathed deeply to calm down.
"I'm studying psychoanalysis and want to go further to criminal-"
He got interrupted by the guess monster.
"No no no, what objectives do you want to reach?" Tendou never lost the gaze of his kouhai, enjoying the intimidating effect he has on him.
"Oh, I'm sorry, all mighty liberator, my goals are to become one of the best international analysists like you. I want to arrest many perpetrators and only have to look at them to realise, if they're guilty or not."
The red haired began to laugh so hard, he nearly fell from his chair and had big tears rolling down his cheeks.
"Oh man, I like you brat. Even though you have a really boring and plain goal. Ah and Tendou does it."
Though Kageyama was overwhelmed with his professor, he still could not suppress his fascination and admiration for this man.

"Well, do you want to go to the arcade? My treat."

The guess monster smirked and stood up suddenly. Arcade...? Does he mean like a NerveGear?
"Sure, thank you very much, Tendou-hasake!" Kageyama stood up and bowed in front of him. The Satan laughed again, shaking his head. "Let's go." They both went to the professors car. It a fuel-based engine from the 21st century. He had not seen such a car despite on tv.

.

"Hah...This is really bringing back the memories of my childhood." Tendou smiled brightly, looking around. Kageyama felt uneasy and stood close to his professor. In the whole arcade were only old people, maybe one or two young men were his age.
After Tendou and Kageyama played some of the arcade games, the red haired went to a claw crane.
He took out some coins, putting them in and started playing.
He was so focused, Kageyama nearly was impressed. But he did not get the stuffed animal. He put some more coins in it, but failed a second time.
As he tried it the third time, he started to smirk, looking at the claw with big and intimidating eyes. Just seeing the reflection of the red light of his professor's eyes, sent shivers down Kageyama's spine.
"You know, Kageyama-kun... Life is like this claw crane..." He whispered against the big box.
"You have to put many coins in it, such as effort, hard work, diligence, capability..." He put some other coins in the claw crane, as he said each coin of life.
"And thereunto the right technic..."
The claw grabbed the stuffed animal, Tendou smirked brightly, his eyes focusing on the animal.
"To gain success."
He finished his sentence, leaned down the claw crane and took out the stuffed animal. Kageyama stood there in shock and impressed.
At this moment he knew, that Satori will be his idol and to be like him would become his only goal in life.

.

The two men were going back to the professors car, while drinking milkshakes.
Many people, who were passing by, stared at the red haired.
Well, his whole appearance was pretty noticeable, he did not even take out his gown.
They got into the car and Tendou drove back to the praxis.
"Uhm... Satori-hasake, your... secretary. He was looking human and he showed emotions, when he smiled at me for example. But still, it still felt off, talking to him. His eyes were completely... empty."
A tensed silence filled the car.
God damn it what did I say? I'm talking to the great guess monster, why did I say that, he thinks that I completely lost it now for sure!
The red haired widened his eyes a bit and then snickered.
"Oh...That means I have a talented underneath me. You're the first one who noticed it, even though I got it down pat. Do you have to go home..?" Tendou said to his kouhai, parking in front of the praxis.

"No I don't."

He wanted to know badly, why his professor reacted like this. "Good, then let me show you something." The red haired smirked, what gave Kageyama goosebumps.

"O-Okay..."

As they reached the office, Tendou went to his book shelve, pulling at a big red lexicon of Elizabethan literature, what activated a mechanism, which opened the door. Kageyama flinched, however, leaned forward to see more.
As the book shelve came to a stop, a flight of stairs was visible.

"Let's go."

The red haired took the lead, smirking slightly mischievous. The black haired hesitated, his guts and brain screaming at him not to gfollow that crazy mad man.
"Uh..O-Okay.." He mumbled and went anyway.
When they arrived at the bottom of the stairs, Kageyama was surrounded by a highly modern laboratory with machines he had never seen before.

Some rumors say, that he has a hidden laboratory, where he conducts some weird inhuman experiments.

The words of the man appeared in his mind and Kageyama slowly felt his anxiety creeping up. Tendou continued to walk stopping at an another room.
When he opened the door Kageyama saw neat stringed tanks with a green liquid, in it human looking puppets, well he hoped that they were just puppets.
"Satori-hasake...?" The black haired said as he slowly backed away. Tendou turned around, facing him and smirking brightly.
"Oh dear, don't be afraid. Those are not corpses. They are... Let me call them Hybrids. And again, do not be afraid, they are not human."
The guess monster went to a tank, stroking the glass.
"Mhm... I like you, so I'll show you my projects. After long and hard work and failings, I manage to make these Hybrids." He typed a number on a touch screen. The green liquid slowly flowed out the tank and as the glass lid opened, steam was coming out of it. Kageyamas eyes widened in shock and somehow in awe and amazement.
"Let me show you, project number 0010. I called him Hinata Shouyou, isn't that a cute name? Sun."
Tendou snickered, looking happily at his Hybrid. Kageyama finally had the courage to go closer to the tank and his professor. He stared at Hinata with big eyes.
"He looks so real... Like... Like a real human boy." The black haired whispered and Tendou nodded happily.
"Yes I know. Wait a second... Serial number 0010, Hinata Shouyou, wake up."
Suddenly, the small boys eyes opened wide, he blinked twice and looked around.
"Hinata Shouyou, serial number 0010 awake." The orange haired shook his head a little, slowly climbing out of the tank. He then started to blush suddenly.
"Gwah! I need clothes!" He tried to cover his body with his arms, what made Tendou laugh.
"I managed to program common human emotions into their brain, as if they would really feel it. Like embarrassment for example." He smirked, but Kageyama only focused on the small shaking boy, blushing slightly too.
"Uhm... Here.." He took off his sweater, carefully slipping it onto the hybrid.
Hinata looked up to him with big eyes, hiding his chin under the collar. "Thank you very much..."
He mumbled, hiding his face.
Tendou chuckled a bit as he watched the scene.
"This one is better than your secretary... He is... I'm really amazed Satori-hasake..." Kageyama was overwhelmed with the whole situation and couldn't stop looking at the small hybrid, who had slipped the sweater over his knees and smelled the collar.
"Semi is serial number 0003, so he's not perfect, but no one noticed it, that he's not a human being, which is why he is a perfect Secretary to me." Tendou smirked and kneed in front of Hinata, stroking his cheek softly. The small boy did not flinch and let him do.
"They see me as a father, that's why he does not reject me. Haha... I'm really proud of this one. Serial number 0010, Hinata Shouyou, fall asleep." He whispered in his ears.

"Hinata Shouyou falls asleep..."

The orange haired repeated, closing his eyes and slumped down. Kageyama immediately felt sad, he wanted to talk to Hinata more.
"This is our secret now, Tobio-kun."
Tendou's gaze, such as his tone, became suddenly serious and the black haired had to gulp.
But not even a second later, Tendou began to laugh and shook his head.
"No worries, as long as you do not tell anyone about this, everything's gonna be fine. Now, can you put Hinata back in the tank and close the glass lid? You have to learn it, because you will work here more often from now on..." Tendou smirked and went back upstairs.
Kageyama's eyes widened, he blushed happily, choking down a scream in excitement.
He slowly went to the hybrid, kneed down and lifted him up. He hesitated a bit, then leaned down to the orange haired and whispered a quiet:
"Serial number 0010 Hinata Shouyou, wake up..."

Nothing happened.

Kageyama sighed disappointed and laid him back in the tank. So he only reacts to Tendou-sama.
He closed the glass lid and watched, as the green liquid filled the tank again. The black haired went back upstairs, still not believing what he saw. But he was excited and looking forward to the work with his professor, Tendou Satori.
