- Cancellation: After the author was arrested for groping minors in early August 2020, artist Shiro Usazaki and publisher Shueisha immediately reacted and announced a few days later that the manga has been cancelled.
- Demand Overload: Matsuki's arrest and the manga's cancellation made the Streisand Effect kick in and copies promptly flew off the shelves.
- Keep Circulating the Tapes: The entire series was pulled from distribution worldwide on August 17 2020, a week after Matsuki's arrest.
- No Export for You: Prior to the manga's delisting, Chapters 26 through 45 were unavailable on Viz, so the first half of "Night on the Galactic Railroad" were not legally available in the States, and the manga's final chapter (123) wasn't officially released on MangaPlus or Viz immediately following Matsuki's arrest.
- Promoted Fangirl: The artist, Shiro Usazaki, was originally known as a popular fanartist, mainly for fellow Weekly Shonen Jump series World Trigger (which she also considers to be her favorite manga) and My Hero Academia, before starting her work on the series and getting serialized in WSJ herself. An interview with the editor revealed that she was actually originally found through her fan arts which led to WSJ contacting her for work on her first one-shot.
- Role-Ending Misdemeanor: Writer Tatsuya Matsuki was caught and arrested for sexually harassing middle-school girls, leading to the manga's cancellation.
- Sleeper Hit: The series slowly but surely gained popularity during its first year of publication, and the first few volumes eventually got heavy reprints with the fifth selling over 50,000 copies in a few days. This baffled even the fans, who didn't expect a series that's neither action-, nor romance- or comedy-focused to survive long in Jump, much less a series so focused on grounded showbiz having an impact at all outside of shoujo manga. Instead it was regularly put forward with color pages and often stood near the top of Jump's table of contents. Sadly, the series' status as this trope would never be fully realized as it was Cut Short in August 2020 due to writer Tatsuya Matsuki's arrest.
- What Could Have Been: There was a stage play adaptation planned for 2022. The manga's cancellation put the kibosh on that during the audition stage.
