No nudity or fanservice, but a few crude jokes here and there.

Occasional comments about breasts. One alien character asks the main character (not understanding what he's saying") if she has "nice jugs".

A male character shows his butt to two female characters in public. He is immediately dissuaded and yelled at. Played as a joke.

The main character works at a bath house and a handful of scenes show characters bathing. No nudity is ever shown and is always obscured by water, camera angles etc. Never used in a sexual context.

Some slapstick violence. Very mild.

One scene towards the end has NieA accidently hit her nose and we see it bleed for a brief moment. Also comedic in context.

Infrequent use of mild profanity like "damn", "hell", "God" (used as exclamation). One use of "bastard".

Some smoking from adult characters.
