   Summary

   “Something really fucking weird is going on.”
   “What?”
   “I don’t know. There’s a new mer, and everyone is convinced he needs to be released right now, even though he’s actively bleeding out.”

   When an injured merman with a purple tail is taken to the Sea Life Rescue & Rehabilitation Center, they know he's different because he doesn't look like any of the other mer species they've seen, but they don't expect him to hypnotize everyone into carrying him back to the ocean with his singing. Hitoshi doesn't expect Katsuki to not be able to hear him.
