Ochita Ojou-sama The Motion Anime is based on the Murapara manga of the same name.

Reya, the daughter of Lord Florence, has long been in love with Ars, a young man who is her personal servant.

The relationship between the two, who hold different positions in society, is truly a "forbidden love", but nothing can stop their spiritual connection and true love, and their relationship gradually develops and grows stronger.

Meanwhile, Rhea is approached by a fat, lecherous old Earl Randolph Decamar, who holds a high office and is essentially Lord Florence's right-hand man.

Naturally, Rhea, who likes Ars, steadfastly refuses Randolph's advances. But some time later, Randolph betrays Florence's family and succeeds in his conscienceless rebellion - Rhea and Ars are captured.

The cunning Randolph sets a condition for Rhea.

If she wants Ars to be granted life, she must give Randolph her intact body....
