Hikaru Sudo is a human doctor who specializes in treating humanoids, who come to him with various problems and worries. Although humanoids suffer from “diseases” like humans, there are “treatment” options available only to them. In a world where humans, humanoids, and robots live alongside one another in daily life, the protagonist is a human doctor who treats humanoids.

This is a wide ranging story that examines the problems that arise due to differences between human and humanoids perspectives, not by focusing on war, terrorism, murder, conspiracy, violence or, hatred, but instead on love and friendship.
