None.

The film contains few actions scenes. It's violent (but not extremely bloody or gory) despite the cute main character and the colourful setting.

Light profanity, but this depends on whether one is viewing the English dub or the Japanese subtitles. Translators will vary.

The teacher in the film is a smoker. Other than that, nothing else.

The second half of the film has an intense feel to it.

The main themes that run throughout the story are about death, grief, desperation, redemption and letting go. Those who experienced a personal loss, will find the film upsetting. At the same time, the film's message is an uplifting one.

A young girl is kidnapped and thrown into another world, and fighting for her life at almost every corner.

Different characters experience the loss of a loved one.
