One day, fish disappeared from the ocean. The Ministry of Fisheries launched a trial operation of the "space fish pond" that had been planned for a long time. The "Onomichi Space Fishery Group" was established in Onomichi and trained space fishermen. In recent years, with the strengthening of the equal employment opportunity law for men and women, the call for "women can also become fishermen" has increased. In this situation, six new space fisherman candidates were selected. The stage is Onomichi, and the goal is the universe. This is a story about the growth of six people who aim to become space fishermen.
