The Diva is dead, but a new one was just born. Rin is separated at birth from her mother and twin brother, Len, to become the new Diva. A Diva must sing to keep the mighty Dragon tranquil until her dying breath. Years later, as he follows the distant sound of Rin's voice, Len sets out on an adventure to find his sister and save her from her fate. He finds out the reason behind the Divas and also meets others who lives have changed due to the Diva's curse.

You can read the light(er) side...or the dark(er) side... Choice is yours. But it's just a parody lmao
