I read it and nothing it says directly says that maou can't have harems. This is obvious but just because it hasn't happened doesn't mean it can't. This may be hard to believe but there are males or characters that don't want harems. Besides it wouldn't fit with the story and if that was really true they would never mention or offer it to him because they know he'll refuse.
