From Transcendence:
Long ago, there existed a land divided into four countries: Sou, Kou, Do, and Ah.
The King of Ah took on a wife from Kou and soon thereafter one from Do, creating a shaky alliance between the three nations. When the Second Queen gave birth to a son, the King cast aside the sickly First Queen and her daughter Aki into the depths of the Palace. But as Fate would have it, Princess Aki encounters a slave named Hakusei, who has peculiar golden hair and sky blue eyes. He promises his life to her and helps her train in the Six Arts under the guidance of the enigmatic merchant Seitetsu. However, when Aki outshines the Prince during a hunt in an attempt to gain her father's acknowledgement, she sparks a war by besmirching Do's honor and drives the Second Queen to poison her mother.
With nothing left but her faithful Hakusei, Aki is banished to the small country of Kou with a vow to return to Ah one day for revenge. But in the face of the mighty allied nations of Do and Ah, will the two survive long enough to carry out Aki´s vow?

“I’ll fix your dress according to your taste this instant!”

“My request.”

“O-Of course! As per your request, there’s only one piece available in the whole Empire.”

People around me listen to me well even if I just frown and sit still. Since I don’t have to live in difficulty, I decided to just comfortably live on as a villainess.

“Father. Is it necessary for you to solve formulas in this slow and inefficient way?”

I thought it would be good to be a rich villainess, so I used all my knowledge.

“Why don’t you give me the honor of escorting the Princess?”

I have had enough of dealing with my father, so why did an unexpected character suddenly appear? What if this person disrupts my plan?

I was falsely accused of attempting to kill my younger sister, who was worshipped as a Saintess. There was not a single person who believed in me, nor was there a person who stood up for me. Not even my blood-related family. I was 14 years old, and it was winter. I, who was Edenbell's Fourth Princess, was miserably beheaded in front of the masses. After the end of my death, I awoke and what came was... "My baby, my precious younger sister." With a delightful smile, he held my small fingers. That warm gesture, warmth, and touch. He sang me a lullaby as he held me gently and swayed.

A spin-off of the Rozen Maiden series.
