This is story related and is achieved during the Kowloon part of the game (2nd part of the game, after leaving Hong Kong).
It's totally not missable in any way, so a guide isn't really necessary. But for reference, you will get this achievement when you meet up with the bowler hat wearing scout on Dragon Street after you have defeated the 3 fighters he tasked you with beating as part of the story.
You don't need to beat the fighters flawlessly, or get the QTEs down perfectly. The achievement still pops in the cutscene on Dragon Street after beating all 3 fighters.
