Oshi no Ko tells a story that explores both the brilliance and darkness of the entertainment industry. The protagonist, Goro, is an obstetrician who meets his favorite idol, Ai Hoshino. However, after a certain incident, he dies and is reincarnated as Aqua, Ai’s child. From that point on, he begins to walk the same path in the entertainment world as her.
