Neiru's Egg was actually her friend from way back. She's notable as the first Wonder Egg Girl to show up in the real world and interact with the protagonist while still alive. Born inside Japan Plati—a corporation focused on creating genetically superior individuals through selective breeding and IVF—she never knew her biological parents, who were chosen purely for their genes.
Her genetic makeup is exceptionally rare: she had heterochromia, albinism, and high intelligence all at once. That combination made her body a major focus for researchers, which created serious complications after her death. Kotobuki Awano eventually became a scientist and doctor, stepping into the role of Doctor Seki, and ended up being her only real friend within the corporation.
