His real technique

This is about hakari, but before i continue, let me establish a fundemental concept.

Techniques in jjk are actions done or phenomena being controled. Gojo can use the infinity that exists everywhere, sukuna can create slashes, kashimo can create or control electricity, and yuta can copy techniques.

But what about hakari? His technique is written as idle gambler, but that's the domain...

Hakari himself states that it has never taken him more than 30 tries to hit jackpot in his domain, a jackpot depending on what mode could have a 1/239 chance...

Kashimo calls him lucky, because he was able to hit jackpot just when he needed it to survive.

During their fight uraume tells hakari they were just "lucky"

So my theory is as follows: hakari's real technique is luck, he is lucky, and he was gifted with the domain according to modern patchinko.

Of course higuruma's case could refute this theory, but i still think hakari's technique is luck itself...
