The Grigori are the three highest-ranking leaders of the True Cross Order. They act as a supreme council, serving as the ultimate authority over all exorcists and Vatican policy.
As the "Three Sages," they are ancient, mysterious, and rarely seen in public.

Ao no Exorcist (Blue Exorcist) features a world where the material human world (Assiah) and the demon world (Gehenna) are mirrored, with locations often serving as both educational spaces and defensive barriers. The structural aesthetic heavily mixes European Gothic, Christian religious imagery, and Japanese traditional architecture to highlight the conflict between ancient demonic entities and structured human defense.

Key Locations and Structural Aesthetic
True Cross Academy (Japan Branch of the Order):
Importance: The central hub of the series, functioning as a "cram school" for training exorcists and a normal high school for innocent students.
Aesthetic: The entrance hall mirrors the Galleria Vittorio Emanuele II in Milan, featuring 19th-century cast-iron and glass-roofed arcades, juxtaposed with gothic-styled dorms.
Structure: It is a massive, complex, and partially submerged facility that seems to defy logical, safe structural design, with a "magical key" system required to navigate its shifting doors and hidden areas (e.g., the underground Exorcist Cram School).
Old Male Dormitory:
Importance: Rin and Yukio’s residence. It is an abandoned, dilapidated site perfect for hiding Rin’s demonic nature.
Aesthetic: Traditional Japanese old-style wood construction, overgrown and quiet, contrasting heavily with the grand, modern, and European look of the main academy campus.
Kyoto Branch Office & Fudoubuji Temple:
Importance: A central location during the Kyoto Impure King arc. Fudoubuji is the historical headquarters of the Myōō Dharani, a group that has fought demons for generations.
Aesthetic: Traditional Japanese, mountain-temple architecture (resembling Kiyomizu-dera and other Kyoto shrines) with red torii gates, massive wooden shrines, and serene, natural surroundings that contrast with the chaotic city of Tokyo.
The Asylum (Former Exorcist Training Dormitory):
Importance: The place where Shiro Fujimoto and Shura Kirigakure trained; its backstory is crucial for understanding the "Blue Night".
Aesthetic: A forgotten, haunted-looking structure that emphasizes the hidden, often violent history of the True Cross Order.
Vatican Main Office:
Importance: The global headquarters of the True Cross Order, providing top-down management of demon-hunting activities.
Aesthetic: Classical Catholic European, representing the ancient, deeply rooted Christian tradition of the Order.

Key Structure Features
Barriers (Anti-Demon Walls): Mephisto uses advanced, often magical technology to create massive barriers over the academy, turning it into a "mechanical prison" or a "Labyrinth Garden" to keep both humans and demons in check.
The Gate (Gehenna Gate): An interdimensional barrier that allows Satan to interact with Assiah, frequently appearing in old shrines or forbidden areas.

1. The True Cross Order
   Purpose: A 2,000-year-old Vatican-backed organization designed to protect Assiah (the human world) from Gehenna (the demon world). They train Exorcists, investigate demonic activity, and maintain the barrier between worlds.
