Maya walks into her father's occult academy ready to burn it all down out of pure spite. Then a time traveler from a dead future shows up, and suddenly she's stuck investigating supernatural mysteries she never wanted to solve with a guy she has no reason to trust. The show knows the real plot isn't saving the world, it's watching two people who actively annoy each other become the reason either of them bothers showing up to school. Every episode lands its comedy through the smallest things: a facial expression, a perfectly timed line, the way Maya's contempt slowly cracks when she realizes Fumiaki might actually be on her side. The premise could have been bigger than the show had time for, but what it actually is, a comedy about two misfits accidentally becoming partners, hits harder than trying to save reality ever could.

Maya returns to Waldstein Academy in 1999 determined to destroy her late father's legacy. The school is known for its occult phenomena, and she despises the obsession that consumed him, so she means to run the place into the ground by taking over as principal. Her plans hit a snag when Fumiaki appears, a spoon-bending time agent with an impossible story: he's from 2012, when aliens have already invaded the planet. His mission is clear. He must find and destroy the Nostradamus Key, the object prophesied to bring about the apocalypse. Time agents carry special cell phones to identify it: photograph a suspect object while imagining its destruction, and a peaceful world in the picture means the key has been found. What begins as an uneasy partnership between a distrustful skeptic and a time traveler becomes something stranger, as the pair look into one bizarre occult occurrence after another in the academy and the town around it.
