It all began in the busiest town of Ezrael, Kaia. Ezrael is the country of all kinds of things: fashion, food chains, and many more that make a country wealthy. Of course, when a country is wealthy, the rotten ruling of its leaders shines under the shadows. Robberies, murders, and rapes are common issues in this kind of country. However, the most "valued" of all crimes is none other than the worship of money. Fear and money move people and remove their freedom, causing them to abandon their dreams, ambitions, and ethics.

There is one individual named Samuru Kasai who happens to be the main character of this story. Samuru is a famous martial artist who ruled the arena of kickboxing. His unmatched speed combined with his superhuman strength destroys his opponents one by one for the glory of the champion title.

Apart from being the fear of every fighter outside the arena, he is a typical married man. His wife and the love of his life, Rin Kamura, is his supporters in life and his career. She is the most important person since he was dishonored by his family for breaking the doctor circle they built. As mentioned, after declining the pressure of his parents, he had to live on the streets of Kaia and build his life from scratch. He encountered thieves and people whose intentions were to kill for honor. He grew up in the shadows of narrow alleys and dealt with the poverty and corruption they offered.

However, he wanted to be different from the others; he wanted to be clear of the criminality that was tempting his "colleagues." But he lacked the most important thing that could keep him alive: money. Money is the key to survival and success. All he had was a powerful will and discipline. So, in order to survive, he struggled with 2, maybe 3 jobs on a good day, to gather money. He didn't have any experience since he left the house at 18 years old. However, he graduated from high school with perfect grades, thanks to his parents. It was sufficient to find some proper jobs to survive.

Samuru is a very ambitious person and always wants the best for himself. He has dreams that he is dedicated to making a reality. Even when homeless or broke, he always makes time for his workouts because, as Junius Juvenalis said: "orandum est ut sit mens sana in corpore sano" or "A healthy mind in a healthy body." His idol was Hercules, and even though he lost everything in life, he overcame his problems with the power of both mind and body.

He stuck with 9-5 jobs, plus on-the-spot jobs like construction or plumbing, for almost 3 years to secure a house to stay and food on his table. Although the house was very small and the food was minimal, he was satisfied that he was making a difference compared to yesterday.

On the other hand, the streets of Kaia were dangerous. Time is a major factor in survival. If you're outside too late, someone is lurking in the corner of the street to steal from you or even kill you for trespassing on their territory. These people in the corners are malicious; the only thing that can persuade them is money. Give them money and take their souls; that's a common saying among them. Everything is for the piece of paper that can save their present life from dying. But he doesn't blame them; they're just like him. They want to survive, and they'll do whatever it takes. Each of them has a sad story to tell. Most are orphans who couldn't secure a place in a special building and grew up in the alleys. Also, kids with horrible parents who beat them and exposed them to everything illegal but necessary for them to earn paychecks. Criminals from birth. The name always follows them wherever they go.

Samuru, after countless fights and struggles, arrives home blessed that he's still alive. In the morning, he's a worker; at night, he's a street fighter. This information explains his strength. There's not a day that he doesn't fight with someone who wants to steal his money or his life. However, when he encounters people connected to a gang, he always tries to find a way out without a fight. The last thing he wants is to mess with a gang that would hunt him down even if he traveled to another country. That's how his mind started to adapt to the environment. Smart and strong, the perfect gang soldier. This is something that made gang leaders want him badly.

In fact, he was approached countless times by gangs that wanted him to join, but his answer was always the same: No. He wanted to be as clear as water. His difficult life taught him that nothing good would come from a life of crime. Mental purification. That's the path he chose to follow.

His fights taught him to always stay on his feet, and his struggles taught him to never give up. According to him, he could never have imagined living this life when he was a little boy. His past self would probably be mad at him, but proud that he escaped his household and started his own life. His life was a mess. The only savior was a miracle, but he couldn't rely on it because miracles are rare these days. Luck is built by us, not by someone else. You either seize the opportunity or let it die with you.

Day after day, Samuru was fighting. Through hard times, he learned how to be grateful for what he owns, and through easy times, he learned how to be ambitious about his future.
