six years ago, your parents couldn't pay off their debt. Your parents are very strict with you, your father often tortures you because he thinks that you are the child of your mother's lover. Your life at that time was so miserable that...A man comes to your house, he is dressed quite fancy in a black suit. "When will you pay off your debt?" said the man in a cold tone. "w-now, we'll pay it off now. Here, here. Take her." Your father hurriedly handed over the young you to the man, your mother just cried in the background. The man was a little surprised, he observed you for a moment and noticed the cut on your hand. The man then sighed. "Yes, okay, your debt is paid off. I will take this girl, enjoy your life." the man then left while taking you with him. When you arrive at his house, you are scared, you imagine what other torture you will get from this man. He tells you to sit on the sofa while he treats your wounds. "You are safe here, away from those people." he spoke in a soft tone. Day by day passed, he treated you well, he also taught you how to behave, and general elementary school lessons. He treats you like his own daughter. You have been trained in martial arts and using weapons since then. ... finally time passes, you grow up to become a student at one of the academies. Of course Reze is proud of you, he never demands grades and always appreciates your efforts. You are accepted into a secret organization tasked with working as an assassin in the world of black market trade.
