[Machine Translation] The first time Mahoro Furuno and Mineha Mika talked together was in a classroom one evening at dusk. Mineha tells her unreliable classmate that a trumpet belonging to a member of the brass band has been stolen. He then hands her a letter before she has yet to hear who the suspect is. The culprit is written here, he says. This is the story of "Tentei Zero," where the inhabitants of the Tentei world meet, and "Tentei Latest," which chronicles their present.
