In the vibrant world of anime and manga, fans are always eager for new adventures and fresh content. On November 4, 2025, the staff behind the beloved series Butt Detective (Oshiri Tantei) announced an exciting development that has fans buzzing with anticipation. Akihiro Sakuchi’s Oshiri Dandy the Young manga will be adapted into an anime, set to premiere within the Butt Detective television series in April 2026.
The announcement coincides with a special day in Japan, known as “Ii Oshiri no Hi” or “Nice Butt Day,” a playful nod to the date 11/4 and the birthday of the Butt Detective character. To celebrate, the anime’s staff revealed a special visual featuring the debut of a new character from the first episode of the upcoming adaptation.
The Oshiri Dandy the Young manga, which focuses on the escapades of Oshiri Tantei’s father, launched in 2020 in Shueisha’s Saikyล Jump magazine. The series is credited to creator Troll, who provided the original story concept and supervision, along with Robinson Haruhara, who handled the original story and composition. The manga’s 11th compiled book volume is set to hit the shelves on November 5.
The Butt Detective television anime has been a staple for fans since its premiere on NHK Educational in May 2018. The series began with a three-episode run and later expanded to a seven-episode series in July 2018. It transitioned to a regular weekly airing in December 2018 and has continued to captivate audiences with new episodes. The latest batch of episodes premiered on October 4, 2025.
In addition to the television series, the Butt Detective franchise has also seen success on the big screen. The third anime film, Eiga Oshiri Tantei: Star and Moon, opened in Japan on March 20, 2024, further expanding the universe of Butt Detective.
The excitement around the upcoming adaptation of Oshiri Dandy the Young is palpable, and fans are eagerly awaiting the new adventures that await them in April 2026.
