In the as of yet unnamed world that Tales of Crestoria is set it, people are required to carry objects known as vision orbs (ビジョンオーブ Bijonoobu) at their side at all times. The images recorded within vision orbs can be transmitted via vision centrals (ビジョンセントラル Bijonsentoraru), structures located in place of importance, like plazas and churches. When a person is to be judged, the vision central shows "footage" from orbs related to the crime and according to the "prayers" sent by the citizens watching the images, the individual in question is judged innocent or guilty. In case the person related to the crime is judged guilty, they are branded with a "stain," and an enforcer (執行者 shikkousha) is dispatched to hunt the criminal down and pass the sentence.
The Stain of Guilt (罪の刻印 Tsumi no Kokuin, "Carved Seal of Sin") is a mark that appears on body part of those acknowledged as sinners, thus becoming a "criminal" chased down by enforcers. The positioning of the mark differs depending on the sin itself. The Stain of Blood Sin (ブラッドシンの刻印 Buraddoshin no Kokuin, "Carved Seal of Blood Sin") is an evolved form of the Stain of Blood Sin, born from the criminal's intent to carry the burden of their sin and overcoming Vicious's selection. The Blood Sin (ブラッドシン Buraddoshin) is a weapon drawn from the Stain of Blood Sin using magic after a person accepts their sin which is then embedded into their blood.
