The Rainbow Fish introduced itself as a kind of God. "I used to be the Marine Goddess of Beauty. All the fishermen used to pray to me for a beautiful wife. The merfolks used to come to me for love advice, and I was extremely adored."
Zero listened to the Rainbow Fish brag about its glorious history. This Rainbow Fish had quite the attitude and was rather haughty. The doctor could understand a little about why the single-scaled fish had no friends. However, he chose to withhold his opinions for now and simply listen.
"With scales the colour of the rainbow, many sea creatures of the deep were attracted to me. For marine animals, light is a very sacred thing meant to be respected, worshipped and revered. It was only natural for them to be envious of my colourful scales. I can understand why everyone disliked me after a while. However, I was so lonely with nobody to talk to. Hence, I asked the Goddess of the Sea, Sedna, for advice."
