The year was 1999 and in Nagano Matsushiro, the private Voltstein Academy proudly stood, earning itself the title "Occult Academy" due to its frequent encounters with supernatural activities. While the dean immersed himself in the study of the occult, the students remained dedicated to their regular academic pursuits.
Upon the dean's demise, Kumashiro Maya - his doubtful daughter, visited the academy. Here, she meets Uchida Fumiaki, a self-declared time traveler from 2012 with an exceptional talent of bending spoons. Together, they explore the eerie incidents taking place within the academy, eventually leading them to the explanation behind Fumiaki's sudden timeslip to 1999.
