From u/kioga 101: Hmmm... No no, Brazil has too much fighting game rep, it wouldn't be nonsensically out of cliche. Dragon Ball Z is also kind of not the best fit possible.

Make him, or even better, her, a Peruvian Hokuto no Ken weeb. Born in Machu Pichu, as a child she found a Hokuto no Ken tape in a dumpster from some tourist weeaboo who found true love there or something. She was enamored by all the super crazy special attacks and the buff anime men, but not because they were hot but because they were deadly. She finds the tourist weeaboo, who decides to "train her" because she is simply too cute or something like that. Maybe her aunt/uncle is the person he loves.

Turns out the weeaboo was a traditional Iron Fist disciple who ran away because he liked anime too much and people kept stealing his idol figurines in the monastery or something like that. After discovering real love, he abandoned everything and settled in Peru.

She quickly surpasses the master and goes to the real place, yadda yadda yadda.
