Siren Caves

Cryaotic, a popular Captain, is left known as the killer of Sweden's Prince after the Prince falls into the ocean during a trip to America. Due to the paranoia, anxiety, and depression he gets from this, he clings onto any hope of the Prince being alive. Since he's so desperate, he agrees to go to the island known as the Siren Caves to search for him.

With the knowledge of his crew losing faith in him, he tries to get the mission done as soon as possible. But, the speed of this mission all relies on the Prince being alive.
