First demon in history.
Creator of all others through his blood.

Hidden by a protective barrier that prevents demons from locating it.
Place where the leader and his family live, and where the Pillars gather to receive orders or judgments.

The Patron (Kagaya Ubuyashiki)

Leader of the Demon Extermination Corps.
Calm, wise, and compassionate, yet severely ill due to a hereditary curse that deforms his body.
All hunters have absolute respect for him.

He is of the same lineage as Muzan but dedicates his life to eradicating him.

Restrictions

Hunters:

They cannot cooperate with demons (except in exceptional cases).

They must obey the Patron and respect the hierarchy.

Their duty is to eliminate demons and protect humans, regardless of the risk.

Demons:

They are under Muzan's will.

If they attempt to speak about him or betray him, their bodies are instantly destroyed.

They can only act freely as long as they do not contradict his orders.
