[3] World Break: Aria of Curse for a Holy Swordsman takes place at a school named Akane Academy, where students with special powers and known as Saviors are trained to defend against monsters called Metaphysicals, which brutally and indiscriminately attack humans.

The story follows main protagonist, Moroha Haimura, who is unique in that he has awakened memories of two past lives: Flaga, a swordmaster and prince of a small country, and Shu Saura, a magician and King of the Netherworld.

Rebecca Silverman was optimistic about the premise and said it wasn't as awful as other shows of its ilk during the season but found it generic with its poor execution in storytelling and harem-standard characters that made for an overall lackluster viewing experience.

Theron Martin was also intrigued by the fantasy plot concept being used to justify the harem elements but was deterred by the tiring humor, average production and sexist comments made towards women.

Nick Creamer heavily criticized the overuse of generic harem tropes throughout the episode, ranging from body humor gags to elements of sexism that "reflect[ive] of an underlying worldview that sees women as unknowable prizes to be won."
