I think the origin of the name Conan in "Detective Conan" is that Kudo Shinichi was asked his name by Mao Lilan after he became smaller. In desperation, he was asked by "Arthur... Conan Doyle" and the name of the Japanese detective novel writer "Edogawa Ranpo" inspired him to name himself "Edogawa Conan".
The protagonist of the Japanese anime "Detective Conan" and a guest role in "Magic Kaito". His true identity is high school detective Kudo Shinichi, known as the "Sherlock Holmes of the Heisei Era" and the "Savior of the Japanese Police."
He was attacked while trying to track members of the black organization and was given a poison codenamed "APTX4869". Although he survived, his body shrank into the size of a first-grade elementary school student. Later, he sought the help of Dr. Agasa, and when his childhood sweetheart girlfriend Mao Lilan asked about his name, he changed his name to Edogawa Conan. At the suggestion of Dr. A Li, he stayed at the home of Xiaolan's father, Mouri Kogoro, and not only solved various cases, but also secretly investigated the black organization.
Catchphrase: "There is only one truth!"
The true identity is high school detective Kudo Shinichi. 17 years old, about 7 years old after taking poison and shrinking his body. His birthday is May 4, which comes from the date when Holmes and Professor Moriarty fell into the Reichenbach Falls on May 4, 1891. The author Gosho Aoyama said that Conan's height will change subtly. He also said that Conan's height is considered small among first graders, while Kudo Shinichi's height is 174cm. The weight is 18.5 kg, and the blood type is unknown, but it is the same as Xiaolan.
I originally lived in 2-chome 21, Rice Flower Town, Tokyo, which is derived from Holmes's address, 221B Baker Street (the Japanese pronunciation of "Baker" and "rice flower" is the same, both are "Beika"). Currently living in the Mori Detective Agency, the address is No. 1, 5-39, Yoneka-cho, Tokyo (original setting of the animation). He studied in Class B of the 1st grade of Tedan Elementary School (Kudo Shinichi was in Class 1A of the 1st grade when he was 7 years old). The mobile phone model is Sony Ericsson W21S → Sony Ericsson Xperia arc S LT18i (comics File.796, TV 673 and up).
The above is purely my personal opinion.
