Amaymon
(重定向自Amaimon)
In demonology, Amaymon (also Amaimon, or Amoymon) is a Prince of Hell, and, according to some Grimoires, the only one who has power over Asmodai.
A curious characteristic of this Spirit is shown during the Evocation of Asmodai to visible appearance, when the Exorcist must stand upright with his Cap or Headdress removed in a show of respect; for if he does not it is Amaymon who will deceive him and doom all his work.
