Four thousand years ago in ancient China, a form of Chinese styled-like kenpō martial arts called Jūken (獣拳, Beast-Fist) was developed.

The other seven students believed that true strength should come from within and engaged their former friends in a great war, ending the fight with a forbidden technique to seal the Kenma powers at the cost of losing their human forms in the process, becoming the Seven Kensei.

It is taught by Grand Master Sha Fu, one of the Seven Kensei, using a sports goods company named SCRTC (スクラッチ, Sukuratchi)[c] as a front.

He rebuilds the Rinjū Hall and brings the long-dead Rin Jūken users back to life as kyonshi to collect Rinki, Geki's polar opposite Qi, to resurrect the Three Kenma so that through them, he can become stronger.

To fight the new Rinjū Hall, Sha Fu trained two youths: Ran Uzaki and Retsu Fukami.

The manga mentioned are Fist of the North Star (北斗の拳, Hokuto no Ken), Dragon Ball (ドラゴンボール, Doragon Bōru, 45), Slam Dunk (スラムダンク, Suramu Danku, 31), Judo-bu Monogatari (柔道部物語, Jūdō-bu Monogatari), Ranma ½ (らんま１／２, Ranma nibun-no-ichi), Shigurui (シグルイ), and others.

They also thank Sammo Hung, Jet Li, Jackie Chan, Donnie Yen, Michelle Yeoh, and Yuen Biao for allowing them to use their names.

With Retsu as judge and Ran as moderator, the contest starts with the dunking match, as clips of the training results of Bat Li, Elephung, and Sharkie are shown, ending with the white Team winning by default.
