Preecha is a scientist investigating the wonders and miracles of a fascinating principle known as ki (spirit energy). While her martial arts talent can't be denied, that's not to say she's only in it to win it either; indeed, Preecha fights for academic purposes, not accolades. She hates the pain, but sure is willing to endure it—as long as it furthers her research into unique and perplexing fight styles. She is the star pupil of Joe Higashi.
