Hayate no Gotoku! Anime

Hayate no Gotoku! (ハヤテのごとく!) anime, based on the manga by Kenjiro Hata, has many references and parodies to other anime as well as some original references such as bleeping out words. Throughout the anime, the audience can see some of the characters breaking the fourth wall. Those that do not break the fourth wall are thinking that the characters are talking to blank space. The narrator is seen talking with Hayate at times, and this makes Hayate realize that there is an audience. Also, some characters may introduce themselves to no one but the audience. Most of the cast have references to their voice actor's previous roles (Nagi for example has an eyecatch where she wears the outfit of Louise's uniform in Zero no Tsukaima).
