LINE Manga Introduces AI Character Chat Feature byUs

Japanese digital comic application LINE Manga has launched a new artificial intelligence service named byUs, enabling users to engage in interactive conversations with fictional characters and generate narrative content. The platform confirms that all intellectual properties utilized within the feature have received explicit approval from their respective creators, with some authors contributing original storylines for participants to experience directly on the app.

The service offers two distinct modes: Official Stories, which adhere strictly to established world-building and character dynamics provided by the source material's creators, and Fan Stories, which allow users to create and share user-generated scenarios that may diverge significantly from canonical plots. This initiative follows a successful pilot on the South Korean platform NAVER WEBTOON in June 2026, where the feature generated fourteen million conversations in ten weeks and boosted viewership metrics.

The initial roster of available characters includes Joy and Esther from Job Change Log, alongside Ren Tachibana and Reo Momotani from Operation True Love. LINE Manga plans to expand the selection of titles and characters in future updates as the service integrates into its broader ecosystem.
