"It Just Works" is a phrase used to describe something that's inner workings don't make sense.

For example, the antagonist's stand of JoJo's Bizzare Adventure: Golden Wind, King Crimson has the ability to erase time. What does that mean? No clue, cause it just works.
King Crimson: I erased time, and leapt past it!
You: Wait, how does that work? What?
King Crimson: It just works.
When you don't need to explain how or why something works, it just does.

Made famous by the infamous Todd Howard.
