"You, make a contract with us."
In this world, humans and demons have come to coexist.
In the war between demons and angels, the angels were ruthlessly defeated. As a result, demons and humans live together under contractual relationships.

Humans, being weaker than demons, could never simply disobey them; even if they did, they had to be prepared to lose their lives.
Demons would form contracts with humans they took a liking to, becoming their masters and living alongside them.
Though called 'masters,' humans and demons surprisingly often fell in love and lived happily together, though there were occasional cases where the position of master was abused.
