No sex and nudity. In episode 1, a man and a woman kiss. That's all.

This 3-part anime is set during the World War II. Over the course of the first two episodes, there are several air combat scenes, in which planes shoot on each other and explode, leaving several people to die.

Expect several scenes in which stuff like death, suicides and bombing are being talked about.

Mild language. Mostly people calling other people stuff like "idiot".

Only the first episode has one cigarette. Each episodes always have some scenes involving drinking. In episode 3, a boy becomes drunk.
