His life takes a dramatic turn when he accidentally falls down a flight of stairs and kisses Urara Shiraishi, the school’s top honor student. This unexpected event triggers a body-swapping phenomenon between the two, revealing that Shiraishi possesses a unique ability tied to witchcraft.

The discovery leads to the revelation that Suzaku High is home to a group of witches, each with distinct supernatural powers. These powers are activated through physical contact, often involving kissing. Yamada, Shiraishi, and their classmates form the Supernatural Studies Club to investigate these abilities and uncover the identities of the seven witches.
