The House of Rebeca was renowned as a family of alchemists. Sasha Rebeca, the family's second daughter, was ostracized throughout her upbringing due to being born out of wedlock.

Nevertheless, Sasha believed that one day her existence would be acknowledged, and so she diligently studied alchemy as a member of the Rebeca family.

Fortunately, Sasha possessed a natural, almost innate talent for alchemy, but all her achievements were stolen by her older sister, who despised her.

These days continued,

Then, on the day Sasha turned fifteen,

Her father declared, "The House of Rebeca has no need for failures," and disowned her from the family.

Sasha, with nowhere to go and utterly at a loss, was then reunited with Nagare, a boy she had met while diligently studying alchemy in the Royal Library, where she had secluded herself in hopes of being useful to her family.

"If that's the case, would you consider working at the royal castle as an alchemist?"

Nagare's true identity was none other than the neighboring country's prince, who had been traveling incognito, and Sasha decided to accept his offer.

Thus, Sasha embarks on a second life, alongside those who truly appreciate her talents.

This is the story of Sasha, an oppressed alchemist, who finds recognition among many in a new land and seizes true happiness.
