•What if Hoshino Ai gave birth to triplets instead of twins? Meet Hoshino Amethyst, the middle child of the Hoshino triplets. She, too, was reborn. She loved Ai just as much as her sick friend Sarina did. She always hung out at the hospital with her even though she wasn't sick. She always found it weird that Sarina had a crush on an ancient doctor but she wanted to keep Sarina happy and never said anything.• •One day, a few days after Sarina's death, Okuda Akari (Hoshino Amethyst) found out about her parents being serial killers. She killed her parents and then slit her own throat. Her last thoughts were how much she missed Sarina, how she wanted to be her sister in her next life and how she wished to be Ai's daughter... after all, Ai is better the rest. Right?•
