Where to continue the Oshi no Ko manga

Oshi no Ko by Aka Akasaka & Mengo Yokoyari, 2020. The manga is complete at 166 chapters across 16 volumes.

• Season 1 (11 episodes): Continue the manga from chapter 41 in volume 5.
• Season 2 (13 episodes): Continue the manga from chapter 81 in volume 9. The finale pulls a scene from a much later chapter forward as a teaser. Keep reading from chapter 81 anyway, Season 3 covers what comes in between.
• Season 3 (11 episodes): Continue the manga from chapter 127 in volume 13. Season 3 stops partway through chapter 127, so start there again to catch the second half you haven't seen yet.
