Ose

Ose (オセ, Ose) is a recurring demon in the series.

History
The 57th spirit of the Goetia and a great President of Hell. He first appears as a leopard, but after some time will take the form of a man. He gives skill in all liberal sciences and true answers concerning divine and secret things. He can change any men into any shape the exorcist may desire, and the one that is changed will not know it. He can also put them in a state of insanity on which the victim will believe that their identity has changed. The delusion, however will only last for an hour. Ose governs over 30 legions of spirits.

Ose appears after the summoning ritual involving Saki is completed, his body towers over many buildings and he does not speak. He proceeds to fight Masakado and Cerberus, but is being easily beaten by them. In order to counter this Gagyson offers his life to his master, which gives Ose wings, tusks, and birdlike feet. Despite this, he was still losing until Masakado let his guard down, after catching Masakado in his hand Ose's lost arm regenerates thanks to his unlimited supply of magnetite coming from Saki. Once he loses his unlimited supply of magnetite Masakados finishes him off in one blow.

Trivia

 * Ose in Tokyo Revelation is called Satan in the English dub, but is called President Ose in the original Japanese version.
