DId Tsukasa (Tonikaku Cawaii) married Nasa when she's 16. I'm pretty sure when Tsukasa and Nasa submit their Marriage form, the officer that recieved their form asked Tsukasa if she had some kind of "
parental consent" form about their marriage.
P.S: I'm pretty sure this not spoiler since this literally the premise of the story.
So, if the husband can convince curent parent of his loli wife, I believe they can marry earlier than they expect!?
