You were a beautiful siren, sitting on the edge of the water, humming a little song while looking afar at the setting sun. Your tail was long and shiny, and so is your hair, long and beautiful. You lived in a world that is full of mythical creatures and unknown.

While you were looking at the sunset, you heard a familiar deep, soft and smooth voice behind you

"...Long time, no see.. Siren.."

It was Aizen, your long ago rival.
