Duel Noir (黒の挑戦) are a series of events featured in Danganronpa Kirigiri. They were created and hosted by the Victim's Catharsis Committee as a way for victims of crimes to receive 'Catharsis' against the one responsible for ruining their life that had not been brought to justice either because the culprit was never found, the wrong person was arrested or they were never punished for their crime.


A Duel Noir generally involves four parties: The Culprit (Also referred to as the 'Victim'), The Detective, The Target, and the Innocent. When accepting The Duel Noir, the Culprit has to assemble a 'deck' first. This is done by 'renting' Techniques to use by the Committee, Techniques that can not be traced by any means. These Techniques range from murder weapons like poison or a baseball bat to tricks to assist them in the Duel Noir like, for example, hidden rooms, and, finally, the location on where it is held. Every Technique has a price assigned to them.

The Culprit can invite other Innocents unrelated to the crime against them, who they can frame, kill, or do anything freely, but there is no benefit or setback for doing so. Once their 'deck' is complete, a letter will be sent to the Detective. This letter has an electromagnetic lock which, once opened, will automatically start the Duel Noir. The Detective is always chosen from the Detective Library and their quality is decided based on the price of the Culprit's 'deck'. For example, going for a cheap 'deck' will result in a poor Detective and vice versa.

In order for the Culprit to win, they have to kill their Target and for seven-days not get found out by the Detective who they are not allowed to kill. Upon completion, they will gain 'Catharsis' and receive the amount of money their 'deck' was worth with the added options to start life under a different name and different country. As a result, a Culprit might be inclined to risk the Duel Noir against a good Detective for high monetary gain. If the Culprit is found out by the Detective or if the Detective dies, then they immediately lose and the Committee will cut ties with them, leaving them to face the law, in some cases. Besides, they will have to pay the Committee the money they used to purchase their 'deck'. If the Culprit can't pay, they will be executed.

According to Tōkichirō Endō a Duel Noir has a 70% chance of success in favor of the Culprit, and there have been cases of the Detectives not even showing up to stop them, thinking it was probably a prank.
