Ratings (レート, rēto) are a system used by the Commission of Counter Ghoul to classify ghouls with respect to their perceived individual ability and threat level.


Ghouls are rated based upon various factors, including their basic strengths, activity levels, influence and hostility towards investigators. In modern-day, there are six rating levels, from SSS (the most powerful) to C (the weakest). In some cases, a tilde (~) is added to the base rating. This indicates that the ghoul is estimated to be at least that strong, but the rating may change once more is known about the subject.

Originally, ghouls were designated degrees, the CCG converted from this system to using the degrees' rating equivalents — e.g. a "special third degree" (特三度, Toku san do) threat became an "SSS" rated ghoul.[1]

Rating Assessment Criteria

The rating of a ghoul is set through evaluation of the ghoul's individual ability. The following criteria are employed to determine the rating according to their individual ability:[2]

SSS rated
Criteria is unclear.
SS rated
Multiple Special Class Investigators are needed.
S+ rated
Equivalent to the ability of an average Special Class Investigator. (approx.)
S- rated
Equivalent to the ability of an average Associate Special Class Investigator. (approx.)
A rated
Comparable to a First Class Investigator. These ghouls are usually set as a target and some ghouls might develop a second tail/tentacle.
B rated
Comparable to a Rank 1 to Rank 3 Investigator. These ghouls should have their Kagune mastered and are usually a small threat to the CCG.
C rated
Ghouls of smaller ability, these ghouls usually can't fight any ghoul investigators and only attack unarmed humans.

In addition to the ghoul's individual ability, the actual damage caused by the ghoul is also evaluated. The rating is set in consideration of the predation and killing incidents committed by the ghoul.

For some ghouls, their influence over other ghouls is also taken into account when ratings are given.[3]
