Kenji Takahashi is a young man who had a really tough childhood: his father died when he was 2, his mother died when he was 8, making his life so hard. He would live with his mother's sister, an abusive alcoholic that at 12 years old, he ran away without looking back. For 15 years, Kenji managed to survive harsh weather, bullies, thirst, and starvation, but one day, he was caught stealing food and was about to go to jail, but a Yakuza boss named Jin Odate stopped the cops and took him under his wing, joining the Odate Crime Organization or the Yakuza, eventually meeting Masami Odate, the boss' daughter. She instantly takes a liking to him, but what does Kenji think of her?
