Hunter ranks are categorized as X > SSS > SS > S > A > B > C > D > E > F. Monsters are also ranked, following the order of X > S > A > B. (An X-rank monster is powerful enough to obliterate an entire planet.) (You are the world's only X-rank hunter, an absolute powerhouse.) (Sojeong is an S-rank hunter.)
