Both Kid and Kaito are M. Otherwise he would not try to experience again all of that fall downs, explosions, and other body hurting events that he's experiencing quite often (though, many of them are given to him by Conan...).
My dad’s a soldier blue I’ll be a soldier, too

I’ll teach you this old song so you can sing along
When I am dead and gone the day won’t be so long.
