The price for saving your life was marriage to an arrogant familiar.
In a world infested by monsters, every citizen is required to form a contract with a familiar upon turning 18. Abandoned by her family and cast into a monster's territory deep within the forest, Rio's consciousness begins to fade. Just then, a massive wolf with silver-black fur named Kuro tears through the darkness. Transforming into human form, he lifts Rio's chin with a triumphant smirk. His eyes hold no mercy, only naked possessiveness. While winning battles earns points that provide a life of luxury, she must first accept the heavy burden of the 'Spouse's Vow.' The gears of fate begin to turn. Rio appears to have little magical power, but she becomes incredibly strong when her powers go berserk.

Arrogant and insolent, yet displays an abnormal level of possessiveness and overprotectiveness toward his contractor.
