True Cross Academy

Lore & Background

The world consists of two dimensions attached as a mirror: Assiah, the material world of humans, and Gehenna, ruled by Satan. Any demon can pass into Assiah through possession, though they usually remain unnoticed to those without prior contact. In response, Exorcists have existed for over two thousand years, operating in several branches globally under the clandestine command of the Vatican. True Cross Academy functions as the Japanese branch of this order, training individuals like Rin Okumura who must master blue flames and demon-slaying weapons such as Kurikara to survive. The curriculum is designed to prepare students for a life where they must identify and destroy demons that wander among humans, often facing threats from those possessing demonic features or powers inherited from Satan himself.

In Their Own Story

Rin Okumura enrolled at the academy after witnessing Father Shiro Fujimoto die protecting him from his own demonic nature. Upon entering the prestigious institution, Rin discovered a shocking truth: his younger twin brother Yukio was not just a student but a veteran Exorcist and one of his teachers. This revelation marked the beginning of Rin's journey to become an Exorcist under Yukio's tutelage. Accompanied by fellow students who quickly became close friends, Rin learned to control the blue flames that ignite from his body and destroy almost anything he touches. The narrative focuses on this training ground where Rin seeks strength specifically to defeat Satan, transforming from a teenager unaware of his lineage into a disciplined fighter within the academy's walls.

Success at the academy requires mastering combat skills against demons that can possess living beings, often requiring the use of specific weapons or abilities inherited from one's lineage. The environment is intense, as seen when Rin draws the sword Kurikara to restrain his powers upon learning his heritage. Students must navigate the pressure of their hidden identities while forming bonds with peers who share the dangerous reality of being Exorcists in training.
