Rainbow Sea is a pixel-art visual novel inspired by the Japanese tale of the Seven Lucky Gods. You play as a Human who wakes up aboard a mysterious treasure ship and is told by one of the gods that you’ve been chosen as a candidate to become a deity. Your reflection in a mirror gives a strange command to lie, and when you step out of the storeroom you meet the Seven Lucky Gods - most of whom are distant or reserved toward you. Over the course of a year at sea, your choices and discoveries decide whether you become a god, return to your previous life, or follow another path.
