Dolphin Divers

In the near future, countries focused on marine development to accommodate the growing population, need for increased food supply and environmental control, creating many floating cities.

The small island of Naginoshima was once popular with tourists, but now it has been mostly forgotten. To bring the island back to its past glory, a marine training school was built using a government subsidy.

However, only 15 people joined the school and they had problems not only with the training, but with the outdated equipment as well.
