Around 1996, Funazaki was informed by a reader that Detective Conan, had similarities to Picasso-kun no tantei note. Funazaki checked Detective Conan and "verified close resemblances." Funazaki considered "these resemble points has possibility of coincidence," so he contacted Shogakukan. Funazaki was told, "The creator might not have read Picasso-kun no tantei note. But I can't deny the possibility that one of his staff members was amused at the situation of Picasso-kun no tantei note and suggested as an idea." Later, he wrote about this inquiry process in the quarterly magazine Parolu, where he declared, "There is no responsibility," "I'll fall into evil way ". Funazaki was offended at the response, and he published the third book as a protest against Aoyama. -->
