Seven Deadly Sins

Seven Deadly Sins (七大罪, Nanataizai) is the term used to refer to seven Diabolus clans who give masks to their members upon maturation, which is proven by slaying their foes and stealing their life spans. Each of the clans has their own unique masks, different from the others, and each clan's masks share the same attributes. The seven attributes are named after the seven deadly sins itself:


 * Pride
 * Envy
 * Wrath
 * Sloth
 * Greed
 * Gluttony
 * Lust

Besides being an indicator of one's clan, the term itself also refers to those from each clan with the most maniac masks who reached adulthood the fastest.
