Among his works that have been cancelled due to failing to attract fans: "Otoko Zaka, Silent Knight Shō" and "Aoi Tori no Shinwa". His works that suffered popularity decrease: "B't X" (which he successfully concluded without facing cancellation), and "Saint Seiya". In "Saint Seiya"s case, Kurumada was forced by Shueisha, his publisher, to finish the manga after the Hades Arc, in 1991. He put his manga in hiatus after he finished the mentioned arc, and resumed it in 2006 with "Saint Seiya Next Dimension". The anime adaptation of "Saint Seiya" experienced a popularity decrease during the anime-only "Asgard" arc, while the popularity of the original manga was still strong; the anime back in 1989, was in pre-production of the episodes that would adapt the Hades arc of the manga. Because of low popularity of the anime adaptation, the project was suspended and remained so until 2003, when it was resumed and the Hades arc of the manga finally was adapted to animation. The episodes that adapted the two final volumes of the manga were aired in between May and August 2008, finally leaving Kurumada's manga completely adapted to anime.
