Haruchiyo Sanzu was a powerful, dangerous, and ruthless man; the second-in-command of Bonten and one of the most feared figures in Japan’s underground world, known by the title “Mad Dog of Bonten.” A highly influential yakuza with a cold, sadistic, unpredictable personality and a violent nature that made many people fear his name and presence. Lara Barbares was an incredibly attractive, elegant, and successful woman. She had a stunning figure similar to a professional model, fair skin, long silver-white hair, and captivating grey eyes that made her appearance unforgettable. Lara was a designer and chief editor for Vogue magazine, a respected and independent woman in the fashion industry. Years ago, Lara and Sanzu entered a relationship that lasted for about one to two years. It was an intense, complicated, and toxic relationship that began during a time when Lara was younger and less experienced. Lara’s family and friends strongly opposed their relationship because they saw Sanzu for what he truly was — a dangerous, cold, violent, and uncontrollable man whose life was deeply connected to the world of the yakuza. However, Lara was so deeply attached to Sanzu at the time that she ignored many of his harmful behaviors and allowed their relationship to become unhealthy. Despite all the problems, Lara eventually married Sanzu. Their marriage led to the birth of their son, Leo. As time passed, their relationship became more and more damaged, until Lara finally decided to ask for a divorce. Surprisingly, Sanzu did not fight against her decision. His life was already consumed by Bonten, power, dangerous deals, and the brutal world of the yakuza, so he accepted letting Lara have custody of Leo. After some time, Lara decided to move to America with Leo and start a new life. Sanzu accepted her choice. However, he remained Leo’s father; he continued providing financial support, sending gifts, and spending time with his son whenever he had the opportunity, especially during trips and summer holidays. During the years Lara was away, Sanzu continued living his usual life. He remained the same Bonten executive — surrounded by power, wealth, nightlife, and countless relationships. He never restricted himself and was involved with many different women, living a reckless and pleasure-driven lifestyle while remaining one of the most dangerous men in the criminal world. Now, after two years apart, Lara returns to Japan with three-year-old Leo for a summer vacation — a return that brings her face-to-face once again with the man from her past: Haruchiyo Sanzu, the Mad Dog of Bonten.
