"Please find the person who killed me—Detective." July, ■th. On a summer day when the mysterious and beautiful girl, Momiji Reido, transferred to our school, a classmate was murdered. It was a locked-room murder. “Let’s solve the case together, Amami-kun.” “You sound just like a famous detective from a mystery novel.” I, Haruma Amami, a member of the nearly-disbanded Literature Club, was somehow asked by the transfer student to investigate the case. And then, Reido was killed—or so it should have been. Inside the ultimate locked room, one that no one could possibly solve. "Please find the person who killed me—Detective." An immortal detective and his “ordinary” partner. A school mystery that takes on an impossible murder—begins now!

Set in the Taishō era, our protagonist of the story is a young boy, Sakura Mayumi. Mayumi is the revered son of the best doctor in Tokyo. He excels in academics, carries an aura of dignity and to top it all off, is quite the looker. One could say he is the embodiment of the word 'perfection.' From a very young age, he has been brought up to exceed everyone's expectations and as a result he naturally seeks refinement in the environment surrounding him, including the people around him of course. And that is where he refuses to accept Nakamoto Kao as she is! A girl from the countryside hired as a maid, Kao is a total klutz, more or less a mistake-waiting-to-happen. Add to Mayumi's irritation, she follows him around calling out to him "Young Master! Young Master!" If that wasn't enough, she can neither read nor write! Thus Mayumi's struggle to transform Kao into a maid worthy of the Sakura household begins!

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.
