French is occasionally used throughout the story; for example, the series is given the French subtitle "La Vierge Marie vous regarde", which means "The Virgin Mary is watching you". In keeping with the tone of the series, formal language is used: is a strictly formal and respectful greeting in Japanese, and is used both to greet and to bid farewell. By custom, this greeting is used often in the Lillian School; this has been one of the distinguishable and popular phrases of the series, and it is used to begin or to finish each volume. The Animax English-language version translates the word as "good day to you".
