Hong Kong Comprehensive starts, Japanese chaos enters, and the system supports - this time, it is not just Hong Kong that dominates.
[Young and Dangerous], [Big Era], [Hot-Blooded High School], [Shonan Pure Love Group]... And even [Slam Dunk]!
In 1990, the streets of Yokohama.
When Long You opened his eyes, he found that he had transformed from a young man in a wheelchair who was busy on the street, to the adopted son of Xiangjiang Detective Long Chengbang - unaccompanied, living in a foreign country, and having all his savings robbed by the local gangsters.
The good news is that he has awakened the "Strongest Little Yakuza System" (Patriotic Enhanced Version) and the "Many Children and Many Blessings Subsystem".
The bad news is that the system has only two ultimate tasks: to become Japan's most powerful delinquent within two years, and to become Alexandre Dumas. If you fail to complete it, you will be obliterated.
What's even more outrageous is that the world is far more than just Hong Kong TV shows.
When he thought he was facing only the grievances of the Young and Dangerous, the Star Dragon Society in Yakuza was hidden in the darkness of Yokohama;
When he thought that the Tsujido High School he transferred to was just an ordinary school, the bad legend of the Shonan Pure Love Group was waiting for him to stir up trouble;
And when the flags of Lily of the Valley, Phoenix Fairy, and the armed front were spread out in front of his eyes, he realized——
This is the ultimate brawl across the worlds of Hong Kong movies, Japanese comics, and games.
From the streets of Xiangjiang to the Japanese campus, from bare-handed to boxing.
A bad boy from Xiangjiang must use his fists and brains to write his own legend in this chaotic land.
