D-Rank to B-Rank (51 – 500 MP): Average to elite academy students and standard field mages.
A-Rank to S-Rank (500+ MP): Masters, headmasters, high nobles, and elite combat commanders.
Monarch / Divine Tier (Unmeasurable): Ancient entities capable of altering geography or overriding natural laws (Azrakar's peak state).
Section 3: World & Setting Guide
Saint Elyria Academy: An elite institution built atop an ancient convergence line.
The Grand Ward: A massive, multi-layered barrier surrounding the campus. It actively suppresses outside malice, screens all incoming students for dark energy, and prevents high-tier monsters or hostile factions from infiltrating.
Class Structure:
Class A–B: High nobles, clan heirs, and high-output magic prodigies.
Class C–D: Standard military track and intermediate mages.
Class E: Low-output students, scholarship commoners, and remedial martial fighters.
Section 4: Deatails
1. Faction Overview
Briefly outline the major groups so readers understand the broader world without needing long exposition in the main chapters:
The Celestial Council: Heavenly entities and their earthly envoys who enforce order and actively hunt high-tier demon signatures.
The Cult of Ash: A radical underground group worshipping the old Demon King's myth, completely unaware that Kazuki wants nothing to do with them.
The Elyrian Senate: The governing body of high nobles who control the academy's funding and favor pure bloodlines over talent.
2. The Weapon & Item Index
Detail Kazuki's starter gear and concealment items:
Ashen Charm (Suppression Tool): An antique wooden pendant Kazuki carved to bind his internal demon mana into his core, keeping the school's Grand Ward from triggering.
Standard Academy Steel Blade: A basic, non-enchanted sword Kazuki uses in class to avoid drawing attention to his combat skills.
3. Glossary of Terms
Astra: The ambient magic energy present in the atmosphere.
Mana Core: The organ within living beings that filters Astra into usable magic.
Demon Genesis: The historical event centuries ago where Azrakar's original army broke through the realms.

(Updated as of Chapter 1)
Active Equipment
The Ashen Charm

Saint Elyria Standard Uniform (Class E Issue)
Grade: Common
