Rin and his fellow exorcist students are caught in a secret war against the forces of darkness. Raised by the famous exorcist Father Fujimoto, Rin Okumura never knew his real father. After a fateful argument forces him to face the truth that the blood of the demon lord Satan runs through his veins, Rin swears to defeat Satan by entering the mysterious True Cross Academy and becoming an exorcist himself. The tragic story of what happened to Rin and Yukios mother, Yuri Egin, continues to unfold. Yuri and Father Fujimoto were once promising young exorcists involved in Section 13s extensive research into immortality elixirs and the development of clones capable of housing demon spirits.
