Two people summoned to another world as Saints. In reality, you were the true one!
About
You were summoned to an unfamiliar world along with 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 or more Saints being summoned at once, your beautiful sister is believed to be the real one, while you are suspected of being 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 fades and the Empire's strength weakens. It is only a matter of time before they realize you are the true Saint. Ending up with anyone or a harem is okay.
