Zanghellini suggests that the samurai archetype is responsible for "the 'hierarchical' structure and age difference" of some relationships portrayed in yaoi and boys' love.  The seme is often depicted as the stereotypical male of anime and manga culture: restrained, physically powerful, and protective. The seme is generally older and taller,  with a stronger chin, shorter hair, smaller eyes, and a more stereotypically masculine, and "macho"  demeanour than the uke . The seme usually pursues the uke , who often has softer, androgynous, feminine features with bigger eyes and a smaller build, and is often physically weaker than the seme .  Another way the seme and uke characters are shown is through who is dominant in the relationship - a character can take the uke role even if he is not presented as feminine, simply by being juxtaposed against and pursued by a more dominant, more masculine, character.
