Amma go with Sarada for now, she acts like she's edgy/cool for no reason. Like when she screamed at Boruto and friends because they saw her walking on the river. Like what?
It's hard to say whether Future Boruto is edgy, Salad fan's seem kinda insecure about Bolt's design in the future, prob because Sasuke trains him, so they think he's 'trying to be cool'. Like how are you trying to be cool when Sasuke is your Master?
It could very well be that Sasuke passed down his teachings to Boruto, and Boruto probably went through something traumatic, even based on the scar. That made him darker.
To that, they'll be eating their words.
