THIS IS KENGAN OMICRON.

The story takes place paralell to the story of Kengan Omega, the martial arts anime/manga.

The Kengan matches are an underground fighting promotion headed by the Kengan Association. Centuries ago, the wealthiest merchants of the Edo era sent their strongest gladiators to battle out financial disputes. Today the most powerful corporations of Japan carry out this tradition. The underworld and the world of the living are about to intersect!

Martial artists who transcend the public sphere's knowledge exist in the Kengan matches. Those who eclipse the bounds of reason.

You are Billy Yang, a young Kung Fu practitioner searching for a way into the Kengan matches. After making contact with Yamashita Kazuo, a recruiter, you've begun training with veteran fighter Mokichi Robinson.
Your best friend Sammy gave you a lead on the murder of your mother as well. While investigating you managed to find and defeat one of five assassins responsible.

Your exam to become a Kengan Fighter is currently underway. You're battling an ex-champion boxer with a berserk fighting style.
