My favourite character is Conan, & then Shinichi & Hattori.
Conan: i think Shinichi do his job more nice when he is Conan. You never imagine the shock when i discover that this little boy was a teenager
Hattori: best friend of Conan, he is too protective with him & Kazoha
too smart also.
Kogoro: the most hilarious character in the serie, i never imagine the serie without him!
Haibara: i like her, too savage & smart, she is with Agasa the one caracter who know Conan truth & organisation truth.
Mitsuhiko: the only child who is a real genius, he is cute when he like Haibara. And the first excited of 3 kids when crime is in close room!
Takagi: smart, lover, too protective with his girlfriend, he like his job & is too close to Conan (he spoke to him like an adult not like a child) & he can be very serious when he want.
My least caracter is Kaito Kid: boring, i become nervous & i skip all episode when i see him. He is too haughty and does not make me any positive effect.
Genta: sorry, we know you love food but you are boring. At least humor exist with him
Ayumi: the most boring kid. Never humor, she is all time kidnapped & she have the I.Q of Genta. I like her but she's boring. At least, i not skip an episode when she was in!
