Xuezhi died, then came back to life.
Good news: The PPT game she played has become real, and she's become a Saniwa.
Bad news: The space-time device malfunctioned. Instead of being sent to her citadel, she was transported to an unfamiliar world.
In this world, the sword-wielding men she knows are playing volleyball, playing tennis, or working as idols. None of them are carrying swords.
Xuezhi: Excuse me?

But life is full of ups and downs, and then more downs. Just as Xuezhi, unable to summon even a single sword, receives a sortie notice.
Xuezhi: When people are speechless, they laugh.
How is she supposed to sortie with no one but herself? Is the Saniwa going to fight alone?
Kitsunezuka (obediently): Based on the time and space you are in, we have selected a sortie team for you. Please depart as soon as possible, Honored Saniwa.
An idol who sings and dances beautifully onstage, a socially anxious tennis team regular with blond hair, a mischievous white-haired teacher, the handsome owner of the flower shop next door...
Facing their varied expressions, Xuezhi gave a soft laugh. "Anyway, you can all start by calling me Master."
Theme: Work hard and live well as a blade
