The episode begins with the arrival of Sei and her group in Morgenhafen, a bustling port city. They are greeted by Oscar, who is already in town on business. They decide to stay at an inn and explore the Morgenhafen market the next day.

Sei, disguised as a merchant's daughter, goes to the market with her bodyguards Jude and Wolff. They hear about an accident at the harbor where a man was seriously injured. Sei wants to help, but she is advised against using her healing magic to avoid drawing attention. Instead, she offers a powerful potion she carries for emergencies, saving the man's life.

Ceyran, the captain of a merchant ship from the Zaidera Empire, visits Sei later to thank her. He insists on compensating her, but she declines. Instead, she asks to see the specialties of Zaidera. To her delight, she finds familiar ingredients like miso and rice.

She decides to cook a Japanese meal and invites everyone, including Aira and Albert. While they wait, Albert and another person discuss Sei's growing fame and potential marriage proposals.

At the end of the episode, the Japanese meal is served, and everyone is excited to try it. Meanwhile, Ceyran decides to stay in the country to find the alchemist who brewed the powerful potion.
