Aru Zonbi Shoujo no Sainan

Description

One day, a group of students from the occult studies club decided to hunt for ancient treasures. They found the information online, and it turned out the valuables were stored in the library's storage room at their school. The students gathered and went out at night to loot their ancestors' heritage. However, they found no treasure except for two coffins containing remarkably preserved mummies of young women. But one of them managed to take the Stone of Life, which was kept inside one of the mummies. The students disturbed the mummies—Baroness Efrosinya Studion and her governess Alma—and they awoke. Without the Stone, Efrosinya will soon die, so the girls must urgently find it.
