Kawanaka (川中,Kawanaka?), commonly referred to as Detective Kawanaka (川中刑事,Takano-keiji?), is a character in the manga and anime franchise Detective Conan.
He meets Conan Edogawa in several cases and his great deduction impresses him only during Detective Takagi's kidnapping, but Conan justifies himself saying which, when he consulted Shinichi Kudo earlier on the phone, that's what he told him.[2] In the end, along with Haibara, Conan shows to the police the trick used by the culprit, even if he making them to believe that is Professor Agasa to find the evidence.[3]
He looks like a drop of water to Kogoro Mori, when he was younger and had not mustache yet.
^Episode 681: The Life-Threatening Broadcast of Love (Part 1). Inspector Shiratori tells to Inspector Megure that they can know where the camera signal is coming from if they let the Cyber Police handle it, but Conan tells to him that they don't think he can anytime soon. The only thing they can investigate on the outside of the tablet is the "On/Off" switch. Anything else, including the touch screen, power button, and the charging connecter have been rendered useless. However, in Inspector Shiratori opinion, if they open the tablet, they can recharge it directly from the inside: if they get the data from the hard drive, they could figure out where the signal is coming from. But, in Conan opinion, after they take it apart, what happens if they can't see Detective Takagi anymore? The culprit is smart enough to modify the buttons and make the touch screen useless. It's safe to assume there's a trap set to shut it down completely if they mess with it. There's another way to avoid that risk by using the tablet's network provider, but this criminal used an overseas server, so it's most likely impossible to find out with so little time.
