Kurata-san is a rookie teacher who has just joined a new school. With little experience as an educator, she must deal with the challenges of teaching a class full of rebellious students.
During a meeting with the principal, she learns that her students will soon undergo a special program designed to transform their attitudes and turn them into model individuals.
However, the method is far stranger than she ever expected: the students will be possessed by the school's own teachers. Surrounded by students controlled by their teachers' personalities, Kurata-sensei must confront this unsettling situation and find a way to restore them to normal.
