After wandering on the brink of life and death due to my sister's magic running wild, I remembered that the world I'm currently in is that of the otome game "Glittering Like Jewels."

And also that I, Langrice Jackberry, am the villainess's older brother.

Now that I've remembered, I must avert this destructive fate.

The villainess's BAD ENDs can be roughly divided into three types.

1) The Downfall Route

My sister, the villainess, incurs the prince's displeasure, and it's discovered that she relentlessly bullied the heroine.

My father's corruption is also exposed, leading to the stripping of his title and exile from the country.

2) The Suicide Route

In this route, my sister, who has truly fallen in love with the prince, is told by him that their engagement is broken at the engagement announcement party, and she commits suicide from the shock.

In this case, only my sister dies, and my family and I face no repercussions.

3) The Jewel Route

This is an END that could be called the highlight of "Glittering Like Jewels."

My sister, who incurred the prince's displeasure, is shockingly subjected to the Jewel Punishment by magic.

My sister, who was turned into a jewel, shatters into pieces in front of everyone, and the still image of the prince and heroine smiling amidst scattered pink jewels was indeed beautiful.

But what shatters is my sister's life.

I will absolutely not allow such a future for my sister.

My sister, as she is now—perhaps because she's young—has a personality completely unlike the haughty, mean, stereotypical villainess from the game.

She's kind and deeply considerate, to the extent that the servants genuinely adore her.

Naturally, I also cherish my sister.

I want to avoid all BAD ENDs, but in the worst case, I'll avoid routes 2 and 3 where my sister dies, and I'll acquire a skill so that we can still live even after a downfall.

So that I can live with my sister and family.
