She is from a manga / anime called Spy × Family which has 8.3 on iMDb. The best spy on the planet pretends to be a family man for deep cover by adopting the girl (who can read minds, he doesn't know this) and quickly marries a woman (who is an assassin also looking for cover, he doesn't know this). They do their missions in-between roleplaying a perfect family.
I'm OK with that. I did find it distracting, because I knew the character (not very well, I thought the kid was the assassin) and the overall conceptual juxtaposition was... weird.
