Koe Naki Niehime to Kokuryuu no Kekkon

Ayame, born into a family of priestesses blessed by the Black Dragon God, possesses a unique ability to heal people through her voice. However, after the death of her parents, she is taken in by her uncle's family who mistreat her, leading to the loss of her voice. Her cousin Mari even takes over Ayame’s rightful position as priestess, and Ayame is eventually offered as a sacrifice to the Black Dragon.

"Why must I be killed like this?! Someone, please help me!"

Her desperate plea brought forth the Black Dragon from the sky. He descends and transforms into a handsome young man, gently takes Ayame's hand, and flies away with her.

Thus begins Ayame’s new life as the bride of Saku, the Black Dragon, living in his mansion situated between the celestial and human worlds. However, Ayame’s cousin Mari, envious of her new status as the beautiful bride of the Black Dragon schemes to steal him away...

A Japanese-style Cinderella story of a gentle-hearted girl who lost her voice and a proud yet compassionate Black Dragon.

The Kozuki family was granted the Black Dragon's blessing, allowing them to heal the sick and purify impurity with their voices alone. But Ayame's life shatters after her parents' death, leaving her at the mercy of her cruel aunt and uncle, who tortured her until she lost her voice. As their daughter, Mari, rises to become the new priestess, Ayame is offered as a sacrifice to the Black Dragon.

"Why do I have to die like this? Please help me!"

In response to her desperate plea, the Black Dragon appears as a striking man and takes her hand, whisking her away to his realm. Chosen to be the bride of the Black Dragon Saku, Ayame finds herself in the enchanting Black Dragon Manor, suspended between the heavens and the human world. But jealousy ignites in Mari, who vows to reclaim Saku and make Ayame suffer once more.
