Aria Blaze is history's most prolific composer. Writing music constantly for upwards of a thousand years will earn you that title. Now, after a defeat which robbed the three sirens of a magic they've known their entire lives, she relies more than ever on her passion to carry her through an uncertain time. Whatever form fate thrusts upon her, she will never stop making music, and that's all that matters...or it would be, if she could get one roommate to stop pestering her, and the other to stop a downward spiral of self-destruction.
