When 倉木麻衣 (Mai Kuraki) sang “Secret of my heart” for 名探偵コナン (Detective Conan) in 2000, there was no reason to imagine that the collaboration would still be active more than a quarter of a century later.
On September 26, 2026, “愛で全部抱きしめて愛して” (Ai de Zenbu Dakishimete Aishite) became her 30th song for the franchise. Nine years earlier, Guinness World Records had already recognized the relationship when it stood at 21 songs.
The number matters less than the time behind it. Mai Kuraki has never become the exclusive voice of Detective Conan: she simply keeps returning to it, while her own music continues to develop elsewhere.
From “Secret of my heart” to “Ai de Zenbu Dakishimete Aishite,” twenty-six years now separate the two ends of the same musical story.
