In the coming years, one in ten people will be Humanoids—advanced machines with AI that mirrors human traits, unmistakable by their horizontal pupils. These unique patients also need a specialist physician. During daylight, Dr. Hikaru Sudou manages a clinic dedicated to Humanoids; at night, as Moggadeet, he carries out illicit surgeries and hunts clues about his vanished mother.
Hikaru meets a range of cases specific to this world: a Humanoid questioning whether she and her backup source are identical, a teen Humanoid unable to enhance his athletic performance, and even a robotic plush bear holding memories of several owners. As technology keeps advancing, increasingly intricate questions about what defines humanity surface. Each breakthrough blurs the line between human and Humanoid, making it harder to pinpoint what truly distinguishes one from another. Thus the clinic becomes a battleground where identity and ethics collide daily.
