~!She was previously a patient named Sarina under Goro's care. Due to her illness, she was wheelchair-bound. After discovering B-Komachi, she had always aspired to be an idol although her condition kept her from achieving her dream. Since being reincarnated as Ruby, she is now working towards her dream of being an idol like Ai. To do so she's currently working with Strawberry Productions to revive B-Komachi along with Arima Kana and Memcho.!~

When a pregnant young starlet appears in Gorou Amemiya’s countryside medical clinic, the doctor takes it upon himself to safely (and secretly) deliver Ai Hoshino’s child so she can make a scandal-free return to the stage. But no good deed goes unpunished, and on the eve of her delivery, he finds himself slain at the hands of Ai’s deluded stalker — and subsequently reborn as Ai’s child, Aquamarine Hoshino! The glitz and glamor of showbiz hide the dark underbelly of the entertainment industry, threatening to dull the shine of his favorite star. Can he help his new mother rise to the top of the charts? And what will he do when unthinkable disaster strikes?
