The story takes place on the grounds of St. Mihailov Academy, a Japanese Eastern Orthodox
school, and draws heavily on religious references from the aforementioned religion. Here it follows the
trials and hardship of two of its students, Oribe Mafuyu and Tomo Yamanobe, until the encounter with a
mysterious, silver-haired, Russian boy named Alexander, or Sasha for short. This pits them and the
whole school in an all-out war between the Church itself and the so-called "Adepts", a sect of individuals
wielding powers linked to the elements of chemistry. Though based on the common magical girl concept
shown in series such as Sailor Moon, the story diverges in depicting extreme acts of bloodshed, brutality
and perversion, and also makes heavy use of fanservice.
