A woman teases a man with a feminine name for making her "call out a girl's name in bed". It's unclear if the two are actually intimately involved, but this is the only instance of innuendo in the series.

The teenage main character begins to remove her top to change, and the bottom of her breasts are briefly visible.

An adult female character frequently wears a very low-cut dress.

References to a great war that preceded the events of the main story are sometimes accompanied with images of the war. Very brief and infrequent in nature.

Some moderate bloody violence occurs in a war setting, including dismembered limbs and pools of blood. These occur mostly in flashbacks, and once in the present.

Flashbacks of gilbert in a pool of his blood while talkingto violet (nothing too graphic.) Episode 8 I believe, is all about war and can be graphic at times, but overall it is a not a gorey show (its about writing letters, lol) yet it is a Masterpiece

Bastard is used alongside lesser profanity.

Alcohol use.
