well we all know Luffy wants one, and I'm not sure but I think the next arc will provide Luffy with a mermaid that can sing. Im basing this off of the fact that mermaids are sometimes thought to be singers. Maybe he will find a siren in the Florian Triangle… but I think the next arc is definitely going to provide us with a new SH.
I apologize if I am reposting some1s idea, but i didnt see one like this.
