Kagi

Kagi was born as a similar experiment to Niko and Luo, though they ultimately ended in failure when they lost control of their physical body at the age of 12. After a period of grieving, Kagi's parents sent them to the Ranta family to act as a babysitter for the young Niko and Luo. Along with their caregiver position, Kagi also helps keep the family's systems organized. With nothing else to do, Kagi relieves their boredom by keeping up with idols. The odd circumstances around their "death" have led Kagi to believe they're an artificial copy of the human they once were. It's because of this belief that Kagi feels ashamed about their desire for connection.
