Asuka Island is a land filled with the remains of an ancient civilisation, with crumbling architecture and gutted stone palaces being a common sight around the jungle island.
Recently however, Asuka Island has come under the protection of Saga, a former marine officer. When Saga first came to this island, it was under attack from pirates. After he and his forces defeated the pirates, they stayed for a short time in order to resupply. During this time, Saga and the local priestess Maya, fell in love.
Due to this, Saga left the marines in order to protect both Asuka Island and Maya from further pirate attacks. He was accompanied by his loyal subordinates, who were charmed by the island's way of life.
