The demon of Wrath, who's Latin name is Ira. He was among the angels who fell with Lucifer after the Fall, along with the other Deadly Sins.

It has been said that the sin of wrath encompassed anger pointed internally as well as externally. Thus suicide was deemed as the ultimate, albeit tragic, expression of hatred directed inwardly, a final rejection of God's gifts. In Hell, at work, he tortures the wrathful sinners and those who committed suicide (that is not to say that all suicides go to Hell, of course); on Earth, he is normally around those who are quick to anger, people with high stress jobs, war, etc. He especially enjoys infecting those with anger that no one would expect to get angry; and at home, in Hell, of course, he spends times with his brothers or bothers Beelzebub.
