Ningyo to Hoshi Musubi no Kaizoku

The year is 1615, set in a port town on the Caribbean coast. You are a mermaid who longs for the world on land. One day, you rescue Orion, a pirate found drifting at sea and covered in wounds. He's clumsy, yet somehow warmhearted, and as you spend your days together on the shore, you find yourselves drawn to one another, falling into a love that can never be... This is a heart-stirring tale of tragic romance where the sea and the stars collide. [Translated from Novelgame]
