Retsu Kaioh is one of Baki’s great martial artists, a master of Chinese kenpo whose skill is presented as the product of 4,000 years of fighting tradition refined into one extremely dangerous man.
The title “Kaioh” marks him as an elite figure within Chinese martial arts, and Retsu carries that reputation with fierce pride. He fights with precision, discipline, and an enormous technical vocabulary, treating combat as both practical violence and proof of the strength of Chinese kenpo.
That pride never makes him static. Retsu repeatedly tests himself against fighters from wildly different schools and eras, adapting his approach without abandoning the tradition at the center of his identity. After losing his right foot in battle with Pickle, he does not retire from competition. Instead, he enters professional boxing, determined to demonstrate that Chinese martial arts can succeed even within another combat sport’s rules.
That combination of confidence and curiosity makes Retsu particularly compelling. He is deadly serious about his craft, but serious does not mean closed-minded.
When a new fighting problem appears, Retsu’s instinct is not to complain that the rules have changed.
It is to find out whether 4,000 years has an answer.
