To commemorate the 30th anniversary of the TV anime " Detective Conan ," based on the manga by Gosho Aoyama , a one-hour special, " Detective Conan Episode ZERO: Kudo Shinichi's Aquarium Incident," aired on Yomiuri TV and Nippon TV on January 3rd. The original opening theme, "Mune ga Doki Doki" by the rock band "The High-Lows," and the original ending theme, "STEP BY STEP" by the rock band "ZIGGY," were played as a surprise. The opening and ending videos pay homage to the original, while also expressing the grand worldview of the series, which has continued to expand over the past 30 years.
On this day's broadcast, the original author, Aoyama, Minami Takayama, who plays Edogawa Conan, Yamaguchi Kappei, who plays Kappei Yamaguchi , and Yamazaki Wakana, who plays Mouri Ran, announced their most memorable TV theme songs. Aoyama chose "Moroshi no Roulette wo Tsurugishite" by the music unit "ZARD," commenting, "The lyrics and melody are just great, and I remember even though I'm tone-deaf, I found myself humming along without realizing it (laughs)." Takayama chose Mai Kuraki's "Your Best Friend," saying, "The image of the two cute characters rowing the trolley was memorable. It made me feel like I was watching a scene from my childhood."
Both Yamazaki and Yamaguchi chose Kuraki's songs. Yamazaki chose "Secret of my heart," saying, "The ending video of Ran singing the chorus of the song still remains in my heart," while Yamaguchi chose "Rose-Colored Life," saying, "It's the opening song of the memorable episode 'Scarlet School Trip,' where Shinichi and Ran finally become lovers, so it's memorable." The series' official YouTube channel has released videos of all the opening and ending themes from the series.
A new visual for "Episode ZERO: Kudo Shinichi's Aquarium Incident" has also been released. It depicts Kuroba Kaito and Nakamori Aoko chatting with ice cream in hand in front of the Tropical Land fountain, which Shinichi witnessed while scouting the area. This visual is paired with the visual of Shinichi and Ran enjoying the aquarium released in September 2025, revealing that the "two shadows" reflected at Shinichi and Ran's feet are Kaito and Aoko. In addition to the release of a special video of the two visuals, it was also announced that the episode "Kid vs. White Horse: The Azure Throne," in which Kaito ( Kaito Kid ) plays a major role, will be broadcast. More details will be announced at a later date.
