Both animation and manga were art forms, but the way they were presented and expressed were slightly different. Animation is an art form that is presented in television, movies, or other media through the adaptation of comics, novels, or other literary works. Compared to comics, animation was more focused on visual effects and action performance in the creation process. Usually, the original work would be deleted or enhanced to meet the performance requirements of television or film media. The similarity between manga and animation was that they were both visual art forms that presented works through painting, comic books, animation, and other forms. They are also loved by readers and audiences, often seen as another form of literary work. Animation usually referred to the combination of animation and comics or an art form that mainly used animation and comics as its main form of expression. In Japan, anime was a very popular art form. Many famous anime works were adapted from comics, such as Detective Conan and One Piece.
