The episode begins with Sei receiving the news that she will be officially introduced to the nobility and celebrities of the kingdom as part of a debut ceremony. The ceremony coincides with the last royal ball of the season, and Sei is informed that she will attend both events. Despite her initial reluctance to be in the spotlight, she accepts the royal invitation.

Sei prepares for the ceremony at the royal palace, where the attendants dress her in magnificent robes. During the ceremony, she is officially presented as the Saint who helped reduce the threat of monsters in Salutania. The ceremony is a success, and Sei rests for a while before the ball.

At the ball, Sei is accompanied by Commander Hawke. She is nervous, but thanks to Hawke's guidance, she handles the social event with grace. She also dances with various partners, including Johan, the director of the institute where she works, and Marquis Drewes. Each man has a different leading style, which fascinates Sei.

At the ball, Sei meets Rayne Salutania, the second prince, who apologizes for his brother's rudeness and expresses his admiration for her. Sei also reunites with her friend Liz, who is delighted to see her so dressed up.

After the ball, Sei reflects on how her life hasn’t changed much despite the formal introduction. She learns that the royal palace has been declining social invitations on her behalf, as she is considered an important figure for the kingdom's defense. The episode ends with the arrival of a messenger informing Sei that the king wishes to discuss something important with her.
