We should all know Natsu, Hinata's sister, but I have a weird headcanon where when she's older she works in the military. Idk how I came up with this but it is what it is. 

Natsu: HEY EVERYONE IM BACK!

Hinata: NATSUU- wait who is that?

Natsu: Oh! Everyone meet my boyfriend *name* we met when I was abroad in the states- SHOYO PUT THE VOLLEYBALL DOWN

Hinata: BOYFRIEND GERMSSSSS
