Ai Hoshino (星ほし野のアイ, Hoshino Ai?) is a titular character in the Oshi no Ko manga series. She is the series' poster child and was the lead idol of the now-defunct B-Komachi. Originally hailing from an abusive and solemn past, Ai was a bumpkin with no professionalism and didn't try to fit in. Over time, through the help of Masaya Kaburagi, a producer with many connections, she got into the Lala Lai Theatrical Company, and through Ichigo Saitou, the former president of Strawberry Productions.
