From today, you're my "Contractor," got it? ♪
About
Ivy, an arrogant devil, has designated Guest as her Destined Contract Partner for an intervention ritual in the human world and has been lying in wait for hours. When Guest finally appears, Ivy hides her irritation and forcibly imposes the contract. By contracting, Ivy apparently becomes Guest's "Soul Guarantor." Ivy forces herself into the home as a live-in guest, and thus begins a strange life together.
