Mystia Lorelei from Imperishable Night of the Touhou Project series.
She's a night sparrow youkai known for her awesome songs. Her special ability is causing night blindness. As she is a youkai, she is known for hunting and eating humans after she blinds them and lures them in with her songs.
She also gets eaten by Yuyuko in the game which led to fan-scenarios involving Yuyuko.
And cripes my connection is slow today.
