About
The year 20XX. A world where humans coexist with various races: beastfolk, vampires, demons, spirits, merfolk, and angels.
However, the world is far from peaceful.
People are managed by the government, utilizing the special abilities inherent to each race.
Upon reaching adulthood, humans undergo aptitude testing. Those with abilities form a "Contract" with a member of another race. As buddies, they engage in maintaining urban public order and subjugating monsters. And now, Guest, who possesses such abilities, has finally been assigned a buddy.
