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. The BAD END routes for the villainess are split into three general types. 1) Destruction Route As a villainess, my sister brought about the Prince’s displeasure when incidents of her bullying the Heroine came to light. With his impropriety exposed and his peerage revoked, Father was exiled out of the country. 2) Suicide Route My sister, who had truly loved the Prince, shocked that the Prince had announced the cancellation of their engagement at the party, committed suicide. In this route, it is only my sister that dies, and my family and I are not condemned. 3) Jewel Route The END that could be said to be the centerpiece of the game. My sister, having displeased the Prince, was sentenced to be turned to a jewel with magic. She had been turned into a jewel the same color as her eyes. She was shattered to pieces in front of everyone. With pink jewels dancing in the midst, the still of the smiling Prince and Heroine was beautiful. However, it was my sister’s life that was smashed. I will absolutely never permit that kind of future for her. Presently, perhaps owing to her young age, her personality did not resemble in the slightest that of the template domineering, ill-tempered villainess in the game. She was kind and with a deep compassion, to the point where she was loved completely by the servants. Naturally I also thought of her as someone precious. Though I want to avoid the BAD END completely, I’ll work so that I can avoid at the worst the second and third routes where my sister dies and provide a viable lifestyle even after ruin. To continue living with my sister and my family.

I, Hanabelle Cantar, am the fiance of this country’s second prince, Remnass-sama. That is until today. Just now, I just had my engagement earnestly broken off by the Prince. Yes, yes, today is the day that I have been eagerly awaiting all this time. My wish was to become a Librarian in the “Tower of Books,” Biblio Tower. Since I’ve had my engagement broken off, I should be free now right? ……So why, is Prince Remnass coming to the tower to see me? He’s a hindrance to my reading, so I will give it my all to have him allow me to humbly push him out!

The world of the count's daughter, Fiori, who loves to grow plants, changed drastically the night she was mistakenly accused of pouring wine on the baron's sweet daughter. Groundless rumors of Fiori being a wicked woman leads to her being ostracized from social circles and her engagement being called off. On top of that, she is ordered to marry Adonis, a frontier count who is feared by the royal family as a mage who deals with monsters! Fiori falls from her peaceful life and despairs of the future. But the Adonis she meets is as warm as the sun... A Cinderella love fantasy about an unfortunate young lady who is surrounded by rumors!

I, Margarete Fondine, an Earl’s daughter recovered my past life’s memories when I was hovering at the boundaries of life and death. I have reincarnated as the heroine in my favorite otome game from my past life. But, hold on a second. Am I really the heroine? In my past life, I also liked web novels. Particularly stories that featured villainesses as the main characters, reading a trifling amount that roughly exceeded three figures. In those stories, the heroine was generally a fool who paid for her mistakes through a tragic end. If I am perhaps not the heroine, then am I not the stalker heroine in the villainess’ story? Whether I’m the heroine or not, it is necessary for me to investigate this first. This is all for the sake of not attracting my future destruction!
