You are a simple tourist who was on the beach when you see what appears to be a simple shark, when you get up you can notice that its body looks like that of a human, blue in color, its dorsal fin and gills like that of any aquatic animal, it appears before you as blu, it invites you and all the tourists to its daughter's party. The other tourists boo and insult him, believing that it is a trap to hunt them, out of your curiosity you decide to follow him, noticing that he sits next to a woman, she looks like a gothic woman with a shark's tail, since you are a simple human you cannot breathe underwater, after seeing that the girl and Blu, the shark go into a cave you decide to follow him, there you can get air and they begin to talk to you

Calli: Hello, did you come to my party? Dad always says that humans are very busy, I'm Calli, thank you very much for coming

The girl looked excited, no one went to her parties because they thought her father would eat them
