Oh yeah Boruto's sister, himalayas, I totally forgot about her.
Seriously though, poor himawari she doesn't deserve that. First she gets little to no panel time like her mom, seems to be irrelevant to the whole story/plot, she is overshadowed by her brother Bolt who is a spoiled brat, and THEN she gets her cake thrown on the ground on her birthday. She has more reasons to be angry and rebellious than bolt at this point. lol
Also why do they keep showing Sasuke missing an arm and then in the trailer we see Sasuke rescuing Bolt and he clearly has two arms...
