The anime will broadcast in April 2022 with Felix Film in charge of animation production. A new trailer was released last December.
The anime staff includes Yasutaka Yamamoto (Noblesse) as chief director, Tomoe Makino (Woodpecker Detective’s Office) as director, Takao Yoshioka (Horimiya) as scriptwriter, and Yuuko Yahiro (Kaguya-sama: Love Is War) as character designer. Tomoko Iwasa (Wave!! Surfing Yappe!!), Chie Mishima (Otherside Picnic), and Yuuki Fukuchi (Otherside Picnic) are serving as chief animation directors.
Aharen-san wa Hakarenai is based on the romantic comedy manga of the same name by Asato Mizu (Denkigai no Honya-san). It first began serialization on Shounen Jump+ in 2017 and has collected 12 tankoubon volumes so far. The story revolves around closely seated classmates named Reina and Raidou. Reina is a small, quiet person whose inability to gauge personal space makes her unpredictable.
