Alongside this announcement, the production has revealed the theme song artists. The opening theme will be Happy Ever After feat. Yu-ka performed by Reina Washio, while the ending theme has been confirmed as Camellia by Yukari Tamura.

The story follows Constance Grail, a quiet and earnest viscount's daughter whose only virtue is her sincerity. After being ensnared by the schemes of her fiancé’s lover, she finds herself pushed into despair. Extending a helping hand is Scarlett Castiel, the infamous duke’s daughter and legendary villainess who was executed ten years earlier. Their fateful encounter sets the stage for a suspenseful fantasy in which a massive conspiracy lurking within aristocratic society gradually comes to light.

In the newly released visual, Constance and Scarlett take center stage, surrounded by Randolph, Lily, and other key characters who appear throughout the series. The illustration heightens anticipation as fans wonder what roles each character will play in the unfolding drama.
