This is represented by ingame by Yuri's Pendant changing colour depending on the level.
In ascending order; Blue, Green, Yellow and, finally, Red.
While in the red, Fox Face will randomly appear in battles and fight Yuri. Though he can be beaten, he will continue to appear until the malice has been cleared out in the Graveyard. Due to the events of the story, Fox Face is replaced in the Europe section of the game with the Four Masks.
Malice can be cleared at any level, regardless, and specific enemies summoned by the Four Masks will only appear at certain colours; Evil 1 at blue, Evil 2 at green, Evil 3 at yellow, and Evil 4 at red. In the Europe section of the game, these are replaced by the similarly named, Gust Eins, Gust Zwei, Gust Drei and finally, Gust Vier.
In addition, the game keeps track of a hidden point score which determines which item is dropped after fighting an Evil or Gust monster. Every regular enemy in the game is allocated a value which contributes to this score. The range of the score is between 1 - 100.
There doesn't appear to be any solid way of determining a given enemy's value, however; some give more points than others.
