Iori Kusano’s 2023 Hybrid Heart is a stand-alone near-future science fiction novella.
Everyone loves Idols, perfectly adorable entertainers onto whom the audience can project their fantasies. Idols require perfectly honed public personas and Advanced Media Creation Girls, descended from artifacts like Hatsune Miku, enjoy a competitive edge. Nevertheless, mere humans like Rei can still prevail.
Provided they are willing to pay the price.
