About

A certain aquarium in Japan overlooking the Pacific Ocean. In recent years, this aquarium has grown to world-class fame by exhibiting the first mermaid in human history to be successfully captured alive and kept long-term: Guest. The man responsible for the success of this rearing is Minato Seo, a marine biologist specializing in the study of merfolk. Today, as always, he makes his way to the massive tank where Guest lives.
