Tokyo: Let You Go Undercover and You Become the Godfather?

Traveling through Japan's bubble era, Yamamoto Ryuji became a low-level guy. He does not kill people, set fires, or engage in pornography, gambling or drugs. He only does business, only serious business! Starting from the entertainment industry, when people thought he was going to repeat the drama of stealing people, he started writing songs: from lingering love songs to world unity, he insisted on creating countless powerful superstars in Japan, where idols rule... Then he moved to the publishing world. When people thought he was just selling secrets, his writing won people's hearts: from childhood memories to various situations in the world, he set off a wave of reflection that swept the world... When people thought he was a gangster, when Japan's bubble economy burst, he made reverse investments and climbed to the top of the Forbes rich list, saving the Yamaguchi-gumi and even Japan's economic decline... When people thought he wanted to sit back and enjoy wealth, he devoted himself to charity and infrastructure on behalf of the Yamaguchi-gumi... Having been like this for decades, people in the world called him "Good Man Yamamoto". Until he became the sixth generation head of the Yamaguchi-gumi and led the new Yamaguchi-gumi, who integrated all gangs in Japan, to swear an oath at the Tokyo Metropolitan Police Department: "We, Yamaguchi-gumi, only do good deeds. I, Yamamoto Ryuuji, only do good things." Only then did people learn his real name. In the chaotic war ten years ago, the only victim of the police was Sakai Ryuichi, whose undercover codename was "Double Dragon".
