Dopamine, Serotonin, Oxytocin (DR. STONE FANFIC)

Prologue

"Alright, next is Senku-Kun!"
The young boy stood up immediately after his teacher called out his name in class. It was an icebreaking session of the students talking about their ambitions.

"I'm going to space," said Senku.

All of his classmates were amazed to hear that.

"An astronaut! That's a great dream. Well, when you grow up..."
"No, I'm going immediately,"

The teacher got interrupted by the ambitious boy. Everyone kept quiet afterwards. After the class ended, Senku broke the silence with his chuckle.

"Kukuku, then again, I'm just a kid who doesn't know the first thing about science,"

He immediately walked away to the library as his goal was to find some books to read.

He said to himself, "I'm going to study every last thing."
"I'm going to try everything."

On his way back from school, he talked with his father, Byakuya. Senku was reading a book at the same time.

"I can't help you. But, Senku, if you're serious, you can accomplish anything through diligent application of science,"

One day, Christmas was around the corner, and Byakuya wanted to surprise Senku with the best gift possible. He went as far as selling his car just to buy him something that his son could cherish for a long time.

"I'm sure Santa Claus will give you the tools you need," Byakuya said happily to himself.

On Christmas Eve, Senku was astonished to see whatever was in his room - a whole set of equipment for scientific research. He couldn't believe his eyes. It left him in awe.

From that day onwards, he started to conduct various experiments and begin with exciting projects. Every of Senku's experiments left people speechless, especially his friend, Taiju.

"You can burn things with the point of light from a magnifying glass," Senku said to himself.

An old man that seemed to be nearby made his comment, "What an adorable experiment!"

On another day, Senku conducted a thermochemistry experiment.
"Sand iron and aluminium foil are awesome!"
"The frying pan is melting from the thermite reaction,"

The same old man as before has been observing Senku's actions.
"How adorable...?"

Another day passed, and Senku brought an odd-looking machine to the school field.

"The liquid oxygen for the injector boils off ten billion per cent at a normal temperature, and it freezes when it's too cold."
"I'll have to keep trying with ethanol for a while until I switch it to kerosene."

Such words that Senku uttered kept the old man shell-shocked.

Senku left the field for a while to get some resources just to find a group of seniors destroying his invention with their feet. Taiju rushed to the scene and defended Senku from those students, leaving Taiju injured afterwards.

Senku went to the school's laboratory to quickly assemble a gun that shot electrical waves and used it against the seniors.

Usually, Taiju will help Senku with his experiments by getting the bits and pieces from stores. Taiju walked into an electrical shop and approached the cashier.

"Sumimasen. I need a Raspberry Pi, a transmitter module, and this thing called a "gyro," He later arrived at Senku's house with the equipment and observed Senku's progress with his invention.

"We'll use a good old Yagi antenna for the receiver. It's what they'd use for TVs," said Senku joyfully.

Whenever Taiju tags along with Senku during experiments, he can be reckless and make careless mistakes, resulting in mini explosions in Senku's apartment block. Byakuya doesn't seem to mind, though.

When Senku was around 11 years old, he decided to make a mini rocket. Of course, Taiju and Yuzuriha wanted to join in with the fun. Taiju walked into the school's laboratory with Yuzuriha and approached his friend.

"Senku, you said you'd try it with a light payload, right? I had Ogawa Yuzuriha-san of the crafts club make us three passengers,"

"It's seriously embarrassing, having a doll of myself. What are you even using these for?" asked Yuzuriha to Taiju.

Taiju didn't answer her question. The trio left the laboratory to go to the field. Senku felt tired during the walk.

He put the three handcrafted dolls into the rocket. After a push of a button, the miniature rocket launched high up into the sky. It managed to fly up high into the blue sky.

"It blew up at a high altitude," said Senku.
"Failed again?!" Taiju started to scratch his head in confusion.
"Not entirely,"

Senku showed his monitor display to Taiju and Yuzuriha. Both of them giggled with excitement the moment they saw the scene.

The three dolls were successfully made outside of Earth into outer space. Senku immediately reminisces about his younger self.

"I'm going to space,"
"I'm going immediately,"

"You can accomplish anything through diligent application of science,"

Senku could hear the voice of his old man clearly in his thoughts.

But that's not the end of his glory days...
