"Don't Leave" is a short film that talks about toxicity in relationships. Onryo represents this toxicity that we can find in anyone, be it in the couple, friends or even family. In this case, Onryo appears in a masculine form when he meets our protagonist Shiory. Due to the theme, I consider that this short film is intended for people over 15 years of age since it is unlikely that people under this age have experienced or can understand a situation as complicated as a toxic relationship. Even so, the style is quite friendly and is not restricted to any age, however it is not recommended for children under 10 years of age.
