Oshi No Ko's first season has wrapped up, foreshadowing the highly anticipated Tokyo Blade arc that fans can't wait to see come to life in Season Two. The first season covers up to the end of Chapter 40, meaning there are over eighty chapters currently out as of mid-July 2023 that have yet to be adapted. Author Aka Akasaka has already stated that Oshi No Ko's end is in sight and heading into its final arc, so the manga is really heating up as all manner of loose ends start to come together.
