Andou Jurai is a high school sophomore with a classic example of chuunibyou, when one day he and the other four members of the Literature Club suddenly obtain super powers. Kanzaki Tomoyo, a bright, determined, closet otaku; Kushikawa Hatoko, a soothing, airheaded girl and Andou's childhood friend; Takanashi Sayumi, a mature older classmen excelling in both sports and academics; and Himegi Chifuyu, a fourth grader who's also the niece of their club's advisor, all obtain unique, powerful powers of their own, yet for some reason Andou only receives the power to produce a dark flame that has absolutely no offensive capabilities. Then, another person with super powers appears before them...
That an evil power will never, 
for all time, dwell in my right arm?
بأنّه لن تثور قوّة شرّيرة بذراعي اليمنى في أحد الأيام؟
¿Que un poder maligno jamás reposará en 
mi brazo derecho hasta el final de los tiempos?
¿Que hasta el día de mi muerte, no habrá
día que un poder maligno resida en mi brazo derecho?
Che un potere malvagio non dimorerà 
mai nel mio braccio destro?
Que um poder malévolo nunca vai residir 
no meu braço direito para todo o sempre?
