Jun Narutaki is the only son of Shanghai's richest Japanese man, Hakuto Narutaki. After his father's death, Jun inherited all of his fortune and work, but he instead he turned down the offer of running his father's business and kept only the money, knowing that it would soon run out quickly. On Jun's 21st birthday, he was down to his last million and donated half of it for his father's company, which was now run by his most trusted relative, his uncle Tsutomu, and kept the other half of the million. Soon after his uncle's death, he was once again the heir to the Narutaki family business which he wanted no part of, but since he was the only heir left able to take the position, he had no choice but to be the new president. Not knowing his uncle's cause of death, he had it investigated and was then targetted by strange men who followed him almost everywhere he went. When he entered a nightclub, he met a woman named Rin who was also targetted by the same people and helped her as she helped him.

- A 21 year-old man who loves relaxation, women, wine, and all the leisures of life. When he was to inherite his father's work and wealth, he kept only the wealth because he had wanted to live peacefully until he died. During the times before his father or uncle were killed, he lived most of his days relaxing in luxury. When he was still young, he was forced to learn martial arts by his father and was sent to a temple where he was strictly taught Shaolin kung-fu, this was the reason why he had devoted his life to relaxation. He is often referred to as a young "dandy man" by his associates but he is not one and also hates to be called one; he prefers to be called "hard-boiled" instead of "dandy", which fits his personality less. He is voiced by Daisuke Ono.
- A 20 year-old woman who has no memories of her past before she was being hunted down by the organization that is chasing her. She is a strong-willed woman who is skilled in martial arts and hiding. She has a strong dislike for Jun because he would often flirt with her and try to relax at bad times. She is often cold towards others despite being very attractive and outgoing, which is needed for her to hide from the organization. She did not learn of her family name, Shoukatsu, until near the end. She is voiced by Miyuki Sawashiro.
- The 57 year-old vice-president of the Narutaki family's business corporation. He is a man who hides his true face under a personality which shows "loyalty" to the Narutaki family and secretly runs the organization that is chasing Jun and Rin. Though he looks weak and cowardly, he is actually a martial artist who mastered many Wudang style kung-fu. He is loosely based on Chow Yun-fat except in personality. He is voiced by Kouichi Hashimoto.
