Mutsumi Mutsu—or just "Mu" to everyone who knows her—is basically running her classroom through a combination of genuine supernatural ability and the healthy fear that comes with it. She's got powers that let her contact the dead and communicate with heaven and hell, which is. pretty intense. On top of that, she can throw up barriers to shield people from spirits and otherworldly threats.
Needless to say, nobody in class is stupid enough to mess with her. She's not ruling through popularity or charm—she's the queen of the classroom because everyone's too spooked to challenge her authority.
