This is the crossover that fans of both franchises have been arguing about for years, and it actually happens exactly how you'd want it to. The fight is pure fanservice stripped of everything else, a showcase of two completely different martial arts philosophies colliding in real time. The runtime doesn't do either series justice, and the animation cuts corners, but neither matters when you're watching your definitive answer get settled on screen.

Two martial arts franchises collide in a single-episode crossover ONA that brings together Hanma Baki and Kengan Ashura. Baki Hanma, billed as the strongest high school student on the planet, squares off against the heir to the Niko Style. The whole premise rests on one question: which of these two fighters will emerge as the winner of their ultimate showdown? Expect a focused action and sports clash built around one headline bout.
