Phantoms are supernatural entities, such as ghosts or youkai, that were considered mere superstition until recently. However, when a brain-infecting virus spreads through society, people's perception of the world shifts as these mythical beings are revealed to have lived alongside humanity all along. This virus has also significantly impacted the next generation, granting them special abilities to combat dangerous phantoms. Haruhiko Ichijou and Mai Kawakami are two individuals who received such power. Haruhiko possesses the ability to summon and seal phantoms through drawings, while Mai channels elemental power into martial arts. Together with the friendly phantom Ruru, they form Team E at Hosea Academy, an organization dedicated to handling these often mischievous beings. In a world where the real and the surreal intertwine, they address the everyday troubles caused by phantoms.
