Nagihiko Fujisaki (藤咲なぎひこ, Fujisaki Nagihiko) is a male hero in the manga and anime series Shugo Chara!, the male ego of "Nadeshiko Fujisaki," and one of the main protagonists of the story. He is voiced by Saeko Chiba.
In Episode 25, Nadeshiko is revealed to be a boy named Nagihiko. It is a tradition in the Fujisaki family for the males to be raised as females as part of their training so that they may play female roles in Japanese dances.
