do you think they have a ninja school

tekken got the caipoeira fighting style pretty spot-on, except for a couple or so moves that are impossible (or really unprobable) to perform

the thing with caipoeira being a "dance" and a "game" is that at first, the fighting style was used by black slaves to defend themselves, but later on, as slavery was banned, caipoeira was still seen as something ethnic and a harmful fighting style instead of culture. So, in order to make caipoeira to be seen as a cultural thing, they started doing caipoeira fights with rhythm (a tambourine and a jew's harp plays a music with a constant rhythm) and showing it off to the public. The fights doesn't involve each one harming and beating each other, but just dealing attacks and avoiding/blocking all of them, like if the two fighters were dancing. The rhythm, being faster or slower also affects how "fast" the fighters will move, they have to move within the rhythm of the one who's playing the instrument. This is why I said that caipoeira is seen as a "dance" and a "game" too.
