The Unknown - Vampire Knight

A girl with no voice and a golden heart enters Cross Academy as a representative of the Senate.

A girl with mismatched eyes, and a scared heart.
Her name was Ryda, and she was a mute Pureblood.

Her heart was shy, gentle, and fearful as a child. After a decade of absence , how will Kaname react to the person his younger sister has become?
How will Yuki, as a human void of her true memories, react to a girl who seems to know her beloved Kaname's secrets?
Will Zero point his Bloody Ross at the disabled girl when she is found walking a Day Class girl back to her dorm?
How will Hanabusa react to being reunited to an old childhood friend?

What secrets is she hiding?
And who's heart has mended hers?

I don't own Vampire Knight or any of its characters or original plot. I just own my OC and anything that derives away from the original everything.
