The thing to know: strong violence, some innuendo or implied sex and light gore, more than a TV-PG usually carries. Beyond that, mild language and a few tense moments.
Our estimate: fine from about 13, higher than the TV-PG suggests, because of the violence.

What is One-Punch Man about?
Saitama is a hero who only became a hero for fun. After three years of “special” training, though, he’s become so strong that he’s practically invincible. In fact, he’s too strong—even his mightiest opponents are taken out with a single punch, and it turns out that being devastatingly powerful is actually kind of a bore. With his passion for being a hero lost along with his hair, yet still faced with new enemies every day, how much longer can he keep it going?
