Many Noh plays have some supernatural creatures such as ghosts, fairies or demons, etc. as the protagonist (Shite), and the play structure is mostly the supporting player (Nohwaki), who is often a flesh-and-blood character, who discovers their stories by questioning.
すなわち、能においては多くの場合、亡霊や神仙、鬼といった超自然的な存在が主役（シテ）であり、常に生身の人間である脇役（ワキ）が彼らの話を聞き出すという構造を持っているのである。
