Sei, an office worker from our world, is transported to another along with a young highschool student. Originally, she is seen to have been summoned by mistake while the highschooler is the "saint" that will destroy the miasma that endangers the magical kingdom. This series was turned into a popular anime in 2023. All nine of these books are unstained, untorn, and their covers are in good condition. Book four is a recycled book from a library, so it has some stickers that obscure the title and side; it is still in tip-top shape!
