1. Ash Badge – The lowest rank. Worn by students who show almost no aura potential. Most are looked down upon or ignored.
2. Bronze Badge – For students who can barely control aura. They often struggle in basic training.
3. Iron Badge – These students show some aura manipulation and combat promise but are still considered weak.
4. Silver Badge – A balanced and disciplined group with stable aura flow and basic combat capabilities.
5. Gold Badge – Students at this level are considered elite. They have strong aura presence and are often team leaders.
6. Platinum Badge – Reserved for top-performing students who show leadership, rare skills, or unique talents.
7. Obsidian Badge – A rare honor. Given only to students who can face dangerous monsters alone. Considered heroes in the academy.
8. Mythril Badge – Almost legendary. Only one or two students every generation may achieve this. Their power is said to rival high-ranking generals.
9. Crimson Crown – Not even a badge, but a title. Given to those whose presence commands fear and respect. Aetherwood has no record of anyone receiving this... yet.
10. Eternal Emblem – The badge of a God slayer. A symbol not officially recognized by the academy but feared by the world. Only given to a being who controls God-level aura, capable of crushing divine entities and rewriting the fate of nations.
