by The third feature-length film of the Butt Detective series, Butt Detective: Star and Moon, will be released on March 20, 2025. The first double interview with Sanpei Yuuko and Sakurai Takahiro has arrived. In addition, 11 never-before-seen stills were also unveiled all at once.
“Butt Detective,” initially written by Troll, is a detective series that has been developed into an app, picture books, reading material, anime, and movies. As of February 2025, the total number of copies of the book series has reached 3,000,000 worldwide. With over 10 million copies sold, the currently airing TV anime is enjoyed by many generations, from children to adults.
The feature-length film version will be released in 2022 as “Butt Detective Seriously” and in 2024 as “Butt Detective Farewell My Beloved Partner,” and “Butt Detective Star and Moon” will be the long-awaited third installment. For the first time, this work will be released at the same time as the two original reading books, “Butt Detective Battle! Pirate Academy Starside” and “Butt Detective Battle! Pirate Academy Moonside.”
Original elements of the anime will also be added, making it twice as enjoyable. One of the major highlights of this work is that “Butt Detective” and “Pirate U” temporarily team up to thwart a terrible plot. Until now, the two have been enemies, and the roles of detective and phantom thief have never been compatible, but now they join forces to face a significant incident.
This is the first time that this has happened in the anime series and even in the theater, and it is no exaggeration to say that this is the birth of the “strongest buddy movie!” In response to this first-ever collaboration, a double interview has arrived from Sanpei Yuuko, who voices Butt Detective, and Sakurai Takahiro, who voices Thief U. They share their thoughts on their first collaboration, so be sure to check it out in preparation for the release.
In addition, 11 stills were unveiled at once ahead of the release. You can see Butt Detective, Brown, and Koala-chan’s innocent yet reliable appearance as they form an idol unit to carry out an undercover investigation, as well as the lineup of unique idol candidates who will be their rivals at the audition. There is also a cut of Butt Detective lying down, completely exhausted, and Brown with tears in his eyes, but what on earth happened? Expectations are rising for the main story.
The third feature-length film of Butt Detective, Butt Detective: Star and Moon, will be released on March 20, 2025. We look forward to hearing more news in the future. Sanpei Yuuko (voice of Butt Detective) Q: Time flies, and this film is the third feature-length film of Butt Detective. It must be very moving for everyone who plays the role, so please tell us your thoughts on this.
I always look forward to the Butt Detective film, which is a little different from the usual TV version and is packed with unique fun. It’s full of volume, full of mysteries, and complete with action and tricks. I always look forward to reading the script. Q: Please tell us your thoughts when you first read the script for this film. It’s always like that, but I’m surprised and think, “Oh, that’s how it is!” “What? Something like this happens!” Furthermore, this time, more than ever, things that had not been revealed before were revealed, and it was a genuinely new development. Q: In this work, you teamed up with your eternal rival, Kaitou U, and temporarily became partners. How was your first tag team? After all, because you know each other so well and think about each other, you can sense the other person’s next move without them saying anything! That’s because of the relationship you have so far. Q: Please tell us the highlights of this work. I guess the highlight of Butt Detective is his idol appearance. But really, everything is a highlight.
The stars, the moon, the ground, the underground. Allies and enemies. Detectives, phantom thieves, idols! There are so many highlights that you might not be able to see them all in one go!? There are so many highlights, so be careful not to miss them. Look for the butts too. Q: When you played Butt Detective dressed as an idol group, did you change your acting style from usual? Also, did you use any idols or singers as references when creating the image? When I saw Pretty’s outfit, I remembered Hikaru Genji.
However, the team name was Pretty, and the three songs and atmosphere were unique, so I didn’t change how I acted. I always try to be confident. Butt Detective’s heart is unfathomable. Q: Finally, please give a message to the viewers.
Thank you for always supporting Butt Detective. Thanks to you, the movie version of Butt Detective has reached its third feature-length film! This time, it’s a dynamic attempt to see the same episode as the original in the movie at the same time! I hope you enjoy both the book and the movie. Sakurai Takahiro (voice of Kaito U) Q: Time flies, and this is the third feature-length film version of Butt Detective.
It must be very emotional for everyone who plays the role, so please tell us your thoughts on this. The best part of the movie version is that you can experience a story on a larger scale than the TV version. I enjoyed the thrilling development that only a feature-length film can offer. I was happy to be able to appear in the film. Q: What were your thoughts when you first read the script for this film? I was excited to see so many members of the Pirate Academy.
Seeing the unique characters rampaging all over the screen was funny and cool. Pirate U also plays a significant role, so watch for that. Q: In this film, you team up with your eternal rival, Butt Detective, and the two of you temporarily cooperate. How was your first team-up? I’m so excited to see Butt Detective and Pirate U team up.
I was moved by the way the rivals trusted each other. Maybe because they knew each other well, they were in perfect sync, and I was moved by the two of them. Q: What are the highlights of this film? This is an important episode that reveals the secrets of Pirate U. A shocking story awaits you! Q: Is there any memorable episode from this dubbing?
