"Most of the stories place them on that island, but some of them place them on Cape Pelorum, Sirenuse, Paestum or Capreae. There could be up to eight of those sirens, lingering around out there on the open seas." Senku grinned.

"But for them to pick an island, it has to be surrounded by rough waters and rocks, they're a must, otherwise it's not dangerous to lure the sailors there. They lure people to their deaths because the story goes, if they should ever fail and someone should resist the siren's call, they would be the ones to die."

He looked pretty pleased with her reaction though. "The Greeks had a lot of stories like that."
