Ranks and EvolutionEdit

Rank D: DeganEdit

Mud Eyes (泥眼 Degan?) are the weakest impurity and the most of them. They have small bodies, weak perception and slow movements. An average adult male exorcist (Ryogo Nagitsuji as standard) can take down ten of them at once. Their risk levels are (from low to high): D and +D.[1]

Rank C: HannyaEdit

Hannya (般若 Hannya?) (A type of monster of Japanese folklore, originally mean "wisdom" in Buddism) are bigger than Degan, but it's much more powerful - can be barely taken down by that kind of average exorcist in Mainland. Their risk levels are (from low to high): C, +C and CC.

Rank B: JaEdit

Snakes ( Jya?) are much stronger and bigger, one needs about ten average exorcists to be taken down. However, at the Tsuchimikado Island they are considered as low level ones. Their appearance are influenced by the people they killed. Their risk levels are (from low to high): B, +B and BB.

Rank A: ShinjaEdit

True Snakes (真蛇 Shinjya?) have human speech and high perception. They need high level exorcist teams and Twelve Guardians to be dealt with. As the impurities hunt each other, this kind of impurity is rare. Their strength is about the power of 50 average exorcists. Impurities start to have sex at this rank. Their risk levels are (from low to high): A, +A and AA.

Rank S: BasaraEdit

Once a Shinja absorbs enough spell power, it evolves into a Basara. A human like impurity that can speak human language. Their power and strength is a much more powerful than most impurities and exorcists. They also gain an ability to use enchanted gears like exorcists do. Only a few of them exists in Magano. Their rank is solely determined by their basara age instead of risk. Their strength is at least the power of 100 average exorcists. Their risk levels are (from low to high): S, +S and SS.


Exorcists and humans that are corrupted by a spell are called Product (生成 Namanari?) or fallen impurities. These impurities are much stronger than normal impurities.Their appearance are much like the normal impurities but their kuji-kiri marks are green. Some of the victims were the Hinatsuki Dormitory students, Mayura Otomi that was later purified by Benio and Rokuro. Their risk levels are ex S or ex A.
