Summary:
One of CLAMP's earlier volumes, Man of Many Faces (originally called 20 Mensou ni Onegai!) revolves around Akira, a young, skilled master thief. While on a mission for his "crime bosses" (family), a kindergarten student by the name of Utako finds out his secret identity. The second volume shows the young pair many years later, with love pending. In a way, this is a prequel to Clamp School Detectives, as it tells the story of Akira before he joined up with the crime-fighting, mystery-solving team.
There are only two volumes of this manga and no anime was ever produced.
