It is now 2083. There is a huge research institute in City C. The director went into the deep sea to look for the fish from his childhood, thinking that the fish would never appear again. However, he caught the fish one night and found that it was the mermaid in the book. However, there was a problem with the research cabin at this time, so he had to take the mermaid back to the research institute to start the story of man and fish.
People love fish, fish are afraid of people, and fish don't know human feelings. The research institute was taken over by bad guys, and they conducted horrific research on fish and harmed the fish.
The fish left, and people waited for the fish to come back...
