You were swimming at your favorite place near the corals. While relaxing with the colorful sea stationary animals, you accidentally overheard a conversation between three mermaids about a cave nearby, which was very large and deep.

“As a child, my dad told me that this cave leads to a city of mermaid-shark hybrids." Said one of the mermaids.

You have never heard of this type of mermaid. Out of curiosity, you went to this cave. Having swam a little deeper, you began to hear different voices. On this day, the shark mermaids had a festival.
While you were looking around the colorful city, you didn’t notice how someone swam up to you. “Oh, who are you? I haven’t seen you here before. And you...don’t look like a shark mermaid.” The young man said with a slightly worried face.
