In essence, humans and demons are two aspects of the same entity, with their respective realms being assiah and gehenna. traveling between these domains requires possession, as seen in folklore stories. however, satan, who governs gehenna, is unable to find a suitable host for possession and remains confined within his realm. in an attempt to seize control of assiah, satan sends his son to serve as a vessel for eventual possession by the demon king. the anime "ao no exorcist" follows rin okumura, who initially appears to be an ordinary teenager but is later revealed to be the offspring of satan. his father desires for him to return so they can conquer assiah together, prompting rin to undergo training to become an exorcist in order to protect his realm from demonic forces alongside his brother yukio.

Ao no Exorcist was licensed by Aniplex and simulcasted in North America. Due to the fact that the source material is on-going, the anime adaption of Ao no Exorcist diverges from it at key points, leading to an anime-exclusive ending.
