Q.E.D. - SHOUMEI SHUURYOU
Q.E.D. ~Shomei Shuryo~ (normally referred to simply as Q.E.D.) is a mystery manga by Motohiro Katou in the same style as Detective Conan and Kindaichi Case Files. Unlike those two, however, the main character Sou Touma does not stumble onto murders with absurd regularity. Instead, he encounters a variety of crimes ranging from murder to fraud. Also unlike his contemporaries (who either work alone or whose partners provide minimal assistance), he often works in tandem with his friend and potential love interest Kana, with him supplying the brain while she acts as brawn.
