Tick tock, tick tock, tick tock. The sound of the clock ticking was the only sound the seven-year-old boy could hear. At this very moment, the boy was looking at a man with a gun in his hands. This random man came into their home and killed his parents because they wouldn't give him what he wanted.

The killer kept on hitting the boy until he bled, still, no matter how much he hurt the boy, the boy didn't faint nor did he scream. He aimed his gun at the boy but hesitated in shooting him. The boy on the other hand looked at the killer of his parents and stared at the gun with no visible emotion on his face. There was no anger, no fear, no sadness, nor regret in that emotionless face of his.

The killer was scared by the boy's nonchalance, he out of fear was going to shoot the boy, just to put an end to this scene. He was ready to pull the trigger. BANG! The killer fell to the ground dead, and a hole was seen in his forehead. The boy looked at the one who shot his enemy dead. There in front of him stood a man who looked to be around the same age as his father.

The man who was wearing something similar to a military uniform stepped forward. He looked at the boy and started smoking, afterwards, he pointed his gun at him.

"Do you want to live?"

The boy couldn't answer immediately since he was injured, but he looked at the man and with the last bit of his strength answered.

"I want to be strong."

The man smiled at the boy's answer.

"Heh, nice answer kid. If you want to live and be strong. First, you must die."

The man aimed at the boy and shot his gun. BANG! Before the boy fainted he heard the man speak.

"From this day forth you're my son, Alexander Samarita."

...

The world of Esterorht had many wars, which were due to it having many countries. And each country differed in their opinions - their opinions on religion, territories, and which was the most powerful of them all, these were some of the different opinions which led to wars.In this war-torn world, being a mercenary was the fastest way to become rich, as well as the fastest way to die.

It had been eight years since Carlo Samarita adopted Alexander. He who was called the messenger of death by his enemies, and allies, suddenly adopting a seven-year-old boy shocked everyone on his squad.

Carlo's squad was a special one. None of them were any good in anything else aside from their own specialty, Carlo was the only one who could somehow do most of everything. Though they couldn't do anything aside from their specialty, they were the best in their own specialty.

They had the best demolition expert, the best marksman, the best stealth operative, the best driver of any kind of vehicle, the best hand-to-hand combat specialist, the best researcher, and the best supporters. Due to all these factors, their little squad was feared throughout the world.

They had a completion rate of 99.70%, out of the numerous missions they had carried out, they only failed once. The squad didn't know how to handle the new recruit who was also the adopted son of their leader. When they first met Alexander no one knew what to say to him, so they just started teaching him their skills and knowledge as ordered by the leader.

Alexander was like a sponge who was able to absorb whatever you taught him quickly. Now after eight years of training, and real-life battle experience, he could be called the perfect soldier. By himself, Alexander had the stunning achievement of a 100% completion rate in all of his missions.

The boy had a drive like no other, and whenever he heard the word mission from his father, something inside his mind always got triggered. Hence whenever he heard the word, he would always try with all his might to complete it no matter the cost.

At the age of ten, he made his first kill, at the age of twelve, he successfully infiltrated an enemy base and killed the enemy leader without anyone noticing, at the age of fourteen he blew up an entire enemy command center.

Though he retained his indifferent expression, he found new warmth in the company of the mercenary squad and was somehow satisfied with this life. He had become strong like his father had promised him.

Yet this kind of lifestyle came to an abrupt end when Carlo made a mistake and got his right leg cut off. This was not a failure of the squad, but more of Carlo's ability. Since he was getting older he had misjudged the opponent's abilities and was caught off guard. Though the squad was able to finish the mission, in the end, Carlo needed to retire.

After appointing a new squad leader for his mercenary group, Carlo alongside his son Alexander returned to his homeland. Carlo has been thinking of going back into normal society, ever since Alexander turned fifteen. He wanted his adopted son to become something more than a soldier who only knew how to fight and kill. Now that he had given him strength, he wished to give him a normal life, and normal happiness.

He wanted to go back to his homeland but couldn't find the right opportunity to tell Alexander, so it was postponed for a few weeks. Then, the incident happened. Though it was unlucky to lose a leg, he now had a real solid reason to retire.

'If a leg is needed to be sacrificed to give my son a normal life, then it's worth it,' he thought.

After years on the battlefield, Carlo had amassed a fortune, and with it founded numerous companies. The companies he owned were varied- he owned a gaming company, a shopping mall, a brand line of bags and shirts, and so on and so forth.

In his home country, in normal society, no one knew his true self as the former leader of the Unique Squad. All the normal people knew him as the owner and founder of numerous companies. Using his money and status, Carlo was able to easily hide the truth from the public eye.

Once the father and son arrived in front of their mansion, a bunch of maids and butlers greeted the two. After which the butlers took their luggage and fixed their rooms. Carlo and Alexander, on the other hand, were in the living room discussing some important matters.

"Nope, it's final, you're going to a public High school," Carlo said with finality in his tone

"Dad, I don't understand why you want me to attend school. With all the knowledge I have, not even mentioning High School, I can probably pass a doctorate-level exam." Alexander asked his dad confused at the whole situation.

Carlo knew his son was smart and didn't really need to go to school since he could just inherit his companies, or return to the battlefield. But that was not the point, he didn't want his son to return to the gloomy battlefield, he wanted his son to have a normal life and happiness, and step one to achieve that, was to get him a girlfriend.

A public school was the best place to find someone his age who might be able to tie him down and bring him normal happiness.

'Tsk I didn't want to do this, but you give me no choice, Alex.' Carlo looked at the stubborn Alex and sighed.

"Fine then, I have a mission for you Alexander Samarita." When Alex heard the word "mission" from his father, he stood upright and did a military salute. When Carlo saw Alex's reaction he nodded.

"The mission objective is to find a girl in the public High School you'll be attending and protect her."

'This way he could bond with a girl, and try his absolute best.'
