What if Yurui is the son of Atsui? Samui's younger brother
Atsui has a hot-headed and spirited attitude
Yurui has an arrogant personality and saw the Cloud being superior than other villages
I know many thinks he could be Darui's son, but they likely would have included that in the show version of the Chunin exams compared to the movie version. They did add the detail about Shinki being Gaara's adopted son in the stats book in the show when Sarada looked him up.
The Eight Tails necklace and face tattoo also suggests being Killer B's son, but very likely just looks up to him as a hero.
It would be an interesting plot twist if he's revealed to be a son of a side character we've met long ago in the past.
And yes, I'm aware many think he could also be Samui's son
