Lua

I first heard of it from an episode of Hawaii Five O. In the episode, Lua is taught in secret, only to native Hawaians and supposed to be only to males but the master is training his daughter because she is his only child. Is that some ancient Hawaiian tradition?

In the end she is forced to fight a female MMA fighter, a pro, and kicks her ass. But then, you can't go by a scripted tv episode right? ANyway I'm curious about Lua now.
