Hayate the Combat Butler
Prior to the 1990s and 2000s no serial in "Weekly Shōnen Sunday" had run over 40 volumes, but that began to change with series such as "Detective Conan", "Major", "Inuyasha", "Karakuri Circus", "", "Hayate the Combat Butler", "Zettai Karen Children" and "Be Blues!", which maintained a high level of popularity.
