Saluntia had just graduated from junior high school and wanted to continue her studies in high school, but lacked the funds to support her studies. One day, she found a brochure about a free school with a dormitory, but it was located in a different city. Without reading further, Saluntia immediately packed her things and left.

The atmosphere suddenly became tense, and the gymnasium plunged into darkness. The new students' panicked voices suddenly fell silent, making the scene even more bizarre.
