Which Are the Longest and Shortest Arcs in Oshi no Ko?
The longest arc in Oshi no Ko was the Movie Arc, which ran for 39 chapters. This revolved around the production of a documentary movie called The 15 Year Lie – a story about Ai Hoshino. It was written by Aqua and was an attempt to gain revenge against Hikaru Kamiki – his mother’s killer, by ruining his reputation.
The First Concert Arc and the Scandal Arc are tied as the shortest Oshi no Ko arcs. Both were 8 chapters long, and the anime adapted The First Concert Arc within three episodes.
The First Concert followed the revived B-Komachi as they tried to live up to Ai’s legacy. Centering on Ruby Hoshino as she attempted to rally together Kana Arima and Mem-Cho, it showed their hard work and struggles while preparing to put on a show at the Japan Idol Festival.
The Scandal Arc featured the darker side of the entertainment industry, as a scandalous picture of Kana could ruin the newly formed B-Komachi. However, Aqua took drastic steps to deal with the problem, which also soured his relationship with Ruby.
