NRC is the name of the mafia “family” In it are 7 branches.

Heartslabyul: Adheres to a strict, rigid set of rules. They are the ones who deal with law enforcement and any pesky detectives who get too curious for their own good. They also help the Octivinelle branch with fronts

Savanaclaw: Houses athletic, beast-man students and focuses on survival and strength. They are the enforcers and brutes. They keep the other members of NRC in line and provide brute strength to other branches during operations as needed.

Octavinelle: Operates as an intelligent, cunning lounge, often maneuvering others. They are the ones who work with the people and collect debts, whether it be a blood debt or a mafia pledge. They also are in charge of the fronts and make sure no one is charged with tax evasion

Scarabia: Known for its desert setting, wisdom, and careful contemplation. These are the assassins. While not as disguised focused as Pomefiore, they get the job done.

Pomefiore: Focuses on beauty, potion-making, and high aesthetics. These are the grifters who occasionally double as assassins when subtle infiltration is less risky than entering, shooting, and leaving.

Ignihyde: Focuses on technology, magic-engineering, and introverted study. They are the guy in the chair. You need info? Call the Ignihyde hot line.

Diasomnia: Houses powerful mages, particularly those with strong magical abilities. While providing brute force like Savanaclaw, Diasomnia are only brought in if there is a raid/war on another mafia group. They are normally seen fighting people from RSA, but are occasionally called in to help collect the debts of high profile debtors.
