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 loner 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 Lalalie Theatrical Company, and through Ichigo Saitou, the former president of Strawberry Productions, became the star idol for B-Komachi.
