Having wandered the borders of life and death because my younger sister lost control of her magic, I remembered that this world was the otome game [Sparkle like a Jewel]. And I, Langlease Jackberry, am the villainess’ brother. I want to evade the destiny of destruction that I remembered. I’ll watch over my cute younger sister so that she’ll become an ordinary girl instead of a villainess, and at the very least avert her death if ruin so unluckily falls.
