In the 16th century, the Franji people introduced a large number of black slaves from West Africa to South America.
These slaves painstakingly practiced martial arts that could be used for vengeance while their hands were bound. It is said that to avoid the watchful eyes of their slave masters, they practiced during gatherings where they reminisced about their homeland, disguising their practice as dance.
This martial art is called Capoeira.
"Capoeira" is not an exceptionally outstanding martial art. Its moves both have a long wind-up and recovery time, and it involves movements that do not fully conform to the basic design philosophy of the human body.
However, it also has significant advantages. Among attacks of the same level, Capoeira's powerful moves are some of the most forceful.
The principle of many techniques in this martial art is the "Rolling Circle," accelerating the heavier and more muscular lower limbs to their limits.
