あらすじ
Continuation of the Kuroshitsuji anime adaptation. At the request of Queen Victoria, Earl Ciel Phantomhive goes to Weston College—a prestigious public academy for boys, known for its traditions and outstanding curriculum—to search for a relative of hers who has not returned home in months. Thanks to his noble status, the 13-year-old Ciel is swiftly able to enroll as a student, while his devilish butler Sebastian Michaelis assumes a teaching position at the school. Ciel does not anticipate being unable to locate the Queen's relative on campus.
