When asked about the universal popularity of Clamp's works, John Oppliger of AnimeNation stated that although it is "not based on originality their artistic skill", they possess a distinct style that "perfectly mesh[es the conventional attributes of shōnen and shōjo manga". He also pointed out that Clamp often "recycles" characters from their own earlier works, which gave rise to "a loosely defined 'Clamp Universe' that gives much of their work a unifying tone", and creates "absorbing, complex narratives that appeal to both male and female readers". All these factors result in "a cult following devoted to anything and everything the group publishes". "" authors stated that "whatever Clamp are on, we'd like some".
