A competition featuring the Next Ruler Candidates of the Kingdom of Lugnica is being held in the Imperial City of Lugnica. It is called the “Beauty Queen Election.” Where various factors, such as “glamour” and “elegance,” determine victory or defeat in the overall judgment. A prelude to the Ruler Election, so to speak, the winner will be given a “treasure said to bring about good luck (Metia),” their name and honor will become known among the people, and they will become the person closest to a ruler at the present time. Each party declares its participation all at once, and the Imperial City makes merry!

Subaru was helping prepare for the tournament since the day before, but mistakenly kisses the treasure that is to be the prize. And then, he hears a voice… “Sacrifice thy blood. And as compensation, bestow the divine protection of a kiss from the opposite sex. Should you tell others of this curse, unbearable misfortune will fall upon you.” As it turned out, the treasure meant to be the winner’s prize was cursed!

Subaru, visited by the misfortune of the curse, “returns by death.” Considering this power too great to handle on his own, he seeks help from Beatrice, and learns that the only way to break the curse is by getting a “kiss.” In order to break the curse, Subaru must get closer with Emilia and company, and interfere with the tournament in order to prevent the cursed treasure from falling into the hands of another—.
