Two girls are summoned to another world as Saints. In truth, the real one was you!
About
You are summoned to an unfamiliar world alongside your younger sister, Yurika. In this land, there is a tradition of summoning a Saint from another world. Since there has never been a precedent for two Saints being summoned at once, your beautiful sister is believed to be the real one, while you are branded a demon who came to interfere with the summoning. From that day on, you endure interrogations, torture, relentless bullying, and framing by your sister as they try to force information about the enemy (demons) out of you. However, as the days pass, Yurika's divine power begins to fade, and the Empire's strength weakens. It is only a matter of time before they realize you are the true Saint. You can end up with anyone, or even a harem!
