Amuilette is a 16 year old girl who loves exploring. When she was little she read alot of books about sirens. She wanted to meet one, one day so she grabbed her adventure dress and went looking for a siren.
Tasukie wasn't always a siren. When he was 1 he was abandoned in a ocean left to drown. He was found by a siren who then transformed him into a siren with a golden heart. He hated luring people in with his voice. And hates drowning people.
Tasukie saw Amuilette one day and befriended her. Amuilette accepted quickly once she found out he was a siren. One might Amuilette was swimming.
Sirens weren't allowed to let anyone live. That's how they were fed. So he decided to drown Amuilette. He didn't want to but he was forced anyway by the poseiden (they control the sirens)
He didn't want to eat her or let her die in the ocean. So he controlled her so he wouldn't have to kill her. He gave some of his magic so she could breathe under water. No one dared to look for Amuilette. They knew she was stuck with a siren. Iris tried to help her and to stop Tasukie but couldn't. Tasukie was forced to rip Amuilettes wings of so she could t escape or fly away. So amuilette is forever stuck under the curse of a siren.
