Sorata Muon is more than a mild-mannered teacher-he is a master thief. By night, Muon dons the disguise and alter-ego known as Mouse, alerting the authorities before a heist just so that he can watch them fail to capture him every time. He is assisted by three scantily clad ladies who also operate under the cover of being teachers. Muon spends a lot of time half-heartedly fending off the advances of his accomplices, but when an art protection society decides that the only way to deal with Mouse is to take him out, he suddenly has a lot more on his mind.
