I've watched up to Episode 74 or so.

I'm confused about the whole Branch-Head family thing. If Hinata's father became head and his twin brother the branch because Hinata's father was born first... why wasn't Hinata's younger sister branched? Is it all children of branch are branched, and all male children of the head after the first are branched?

What does the writing on the Naruto's card mean? We get a good look at it in Episode 69 two different times... ABNU-AONE didn't translate the stuff on the graph (the one that resembles DDR's groove radar)... Is it actually supposed to mean anything? Curious.
