Occasional mild fantasy violence, mostly of a comic nature. No blood or serious injury is depicted.

A side character has a condition that causes him to cough up blood. Played for laughs.

Occasional mild coarse/slang language ('damn', 'hell', 'ass', 'bastard', 'crap', 'suck', 'freaking') in the English dub and official subtitles.

The word 'hell' is used sometimes as puns to items in the demon world; for example, a hell phone instead of a cell phone.
