[Machine Translation] Sei enjoyed exploring the port town, helping the captain of a foreign country, Zaidera, with a homemade potion, and discovering a long-sought-after Japanese food ingredient. If only we had miso as well as rice, we could eat Japanese food! Sei's interest in the foreign country was growing stronger when a disturbing report came in. A prince from Zaidera is coming to Japan as a foreign student.

The researcher shows his true colors and jointly develops a new potion with the prince!
