Boruto's family has:
Hinata Hyuga - His mother and she's also a really good person, he loves her alot.
Himawari - She's his younger sister, she's 10 year's old and also a really powerful ninja, even as a kid, she already activated her Byakugan.
Naruto - He is Boruto's dad, but he's really absent, to a point that Boruto pretends to not care so it hurts less, he loves his dad, but he just wishes that they could have more time together. That's why he's always a troublemaker.
