The Seven Deadly Sins stand at its very top.
Academy Rankings
Rankings exist from 1st to 100th. Entering the top 100 makes you an elite. Ranking above 50th ensures a secure future. Ranking in the top 10 leads to scouting by national agencies. ──And ranks 1st through 7th are in a league of their own.
Ability Ranks
C-Rank, B-Rank, A-Rank, S-Rank, EX-Rank... Only the Seven Deadly Sins possess special abilities called Origin Abilities. They are fundamentally different from other powers.
