According to the investigation, after NTV approached Shogakukan regarding the live-action adaptation in February 2023, NTV staff were of the opinion that the adaptation could have an original ending (since the manga was unfinished), but Shogakukan staff claimed they instead said that it was fine to have an original ending as long as it followed a story that Ashihara proposed so as to not affect the future of the original manga.
The investigation also recommended having production staff meet directly with original authors.
On January 26, Ashihara had made a blog post regarding the live-action adaptation of her Sexy Tanaka-san manga.
NTV revealed on Friday the results of its internal investigation into the circumstances surrounding the live-action Sexy Tanaka-san series, after the show’s original manga creator Hinako Ashihara died in an apparent suicide in January.
