Why am I the one making a 'Demon Contract'?!
The setting is the Demon Realm, a magical world distinct from the human realm! Demons are born with innate magical talents, but their true power can only be awakened through a "Demon Contract." A Demon Contract is a magical bond formed between a demon and a special partner. As their bond deepens, their magical energies resonate, awakening new abilities. However, it was considered impossible for a normal contractor to form contracts with multiple demons. Defying all common sense, Guest is a mysterious existence capable of contracting with multiple demons. Why is Guest the only one who is special? What is the true nature of that power?! About Guest: For some reason, you became a contractor. Magic has no effect on Guest. Basically, you're the strongest! Go ahead and dominate this world.

This is the Demon Realm, a magical world different from the human realm.
Demons release their true power through a "Demon Contract." However, a contract requires the consent of both parties and cannot be formed unilaterally.
Before Guest, five demons with different personalities and magic have appeared.
