Kingdom Island

Kingdom Island (キングダム島) is the primary setting featured in Ocean Blue. Its remains appear as a minor setting in Regional Crusaders.

It was a large archipelago located far south-east of the Corona region mainland, consisting of one massive island and several small islands surrounding it. Home to a few mythical and legendary creatures, the island was a popular resort destination and attracted a lot of tourists from other regions, while also having a lot of factories and laboratories.

In 2022, however, Dakera and the Chaos Agency used the island for their activities, kidnapping several residents of the island. After the battles that took place, Kingdom Island was destroyed and in 2027, Kyotaro's group traveled to what remained in a brief expedition.
