World Trigger Tops Oricon's Comic Ranking for October
The 30th volume of Daisuke Ashihara's World Trigger manga topped the chart, selling 280,785 copies. The volume shipped in Japan on October 2. The manga's anime adaptation is getting a "Reboot Project" that will re-adapt the original manga from the first chapter and will include the Border Enlistment Arc, Large-Scale Invasion Arc, and B-Rank Wars Arc. Toei Animation will continue to produce the anime, and the anime's staff stated it will be a "powered up World Trigger 1st Season."
The 33rd volume of Taiki Kawakami's That Time I Got Reincarnated as a Slime (Tensei Shitara Slime Datta Ken) manga, based on Fuse and Mitz Vah's light novel series of the same title, ranked at #2 selling 261,337 copies. The volume shipped in Japan on October 8. The manga is notable for being the basis of the story's long-running anime adaptation (as opposed to the light novel series itself). Kodansha USA Publishing releases the manga in English. The third cours (quarter of a year) of the anime adaptation's fourth season will debut in July 2027.
The 109th volume of Gōshō Aoyama's Case Closed manga ranked at #3 selling 209,686 copies. The volume shipped in Japan on October 16. Detective Conan: 30-gō Satsujin Jiken (The Counterfeit Case of Ultra 30), the franchise's first new two-hour special in 10 years, debuted in Japan on September 25. Detective Conan: Highway no Datenshi (Detective Conan: Fallen Angel of the Highway), the franchise's 29th film, opened in Japan on April 10.
