To the learned scholar Akihiko Chuuzenji, every enigma of existence can be unraveled by stark logic. Once he takes a post as a Japanese instructor at Tokyo Metropolitan Mitogawa High, he meets Kanna Kusakabe, an effervescent youth whose eagerness to aid others frequently lands her in mishap. When Kanna discovers that a peer has been doomed by a specter, she resolves to probe the campus after dark, only to realize that the alleged phantom was in fact Akihiko. Reluctant to reveal to classmates a concealed chamber teeming with prohibited tomes where he labors, Akihiko opts to circulate the tale that Kanna singlehandedly banished the spirit.
To Kanna"s dismay, she is now regarded as a paranormal savant by her peers, who compel her to examine numerous uncanny incidents. Yet she can count on her teacher Akihiko"s support, and though he is a stern figure, he remains steadfast in proving that rationality triumphs over superstition. His unwavering conviction inspires both students and faculty alike, fostering a culture where skepticism is cherished over fear and encourages critical daily inquiry.
