a troublemaker, but has brilliant reasoning powers and blows a party horn when he thinks about something. John H. Watson (pronounced "Watoson" in the Japanese) is a transfer student from Australia to Beeton School and roommate of Holmes (pronounced "Homuzu" in the Japanese). He has a strong sense of justice and writes about their investigations in a notebook called "Watoson memo" (memo by John H. Watson), which is reported to the school paper, the "Strand Wall Poster" (a wall newspaper).
