I think that Haneda Shuukichi is the second oldest brother of masumi. It fits all the hints and he knew that conan had solved the case on his introductory case... And the wizard is conan..according to me she refers to him as a wizard because there is an old saying that dont put your nose into others business..... I can be wrong but this is my opinion... You can point out the things i have missed but to completely explain this i have to refer my notes of deduction which are not available to me right now so.... This is my theory guys.... I m not saying that i m right....
