A crumpled test paper sails into the trash, and the final bell of Kamome Academy rings not with danger but with the thud of a textbook hitting the desk. Nene Yashiro, first-year occult lover and certified assistant to the Seventh Mystery, is no longer bound to a toilet stall for the afternoon — she is free, and so, inexplicably, is Hanako-kun. The ghost who balances the scale between the living and the supernatural now balances something far more treacherous: a boredom so profound he will literally change genders out of curiosity, catch a cold he has no business catching, and drag Nene into games where the stakes are nothing but their own dignity .

What happens when the keeper of rumors clocks out? Kou Minamoto, the exorcist with a family legacy, gets roped into nonsense no lineage prepared him for. Spectral entities that normal eyes cannot perceive are not scheming in the shadows — they are getting pranked, dodging flying erasers, and watching two idiots turn the mundane into a sideways spectacle . Every quiet moment between disasters is a world-shaking secret waiting to be tripped over, and the after-school hours prove one thing the Seven Mysteries never advertised: the weirdest phenomenon at this academy is not a haunting. It is what Hanako-kun does with a free afternoon.
