Taki is a high school teenager who must balance his work and social life while pursuing a future career in architecture. However, Taki’s life takes a dramatic twist as he finds himself inside Mistsuha Miyamizu’s body. After finding out their dilemma, Taki must work alongside Mitsuha to resolve their body switch problem.

She is a female high school student who serves as her town’s priestess in her family shrine. At the same time, Mitsuha doesn’t enjoy her rural life because of her father’s stern desires and the criticism she receives as a shrine maiden.

Even though she achieved her goal by body-switching with Taki, she eventually learned about other issues that would spell doom for her and her entire town.

Katsuhiko Teshigawara is one of Mitsuha’s friends with expertise in machinery and explosives. Though his parents are never named, Katsuhiko worked under his father as a construction worker.
