Temozarela is an arch-angel who fought on God's side in the war against Lucifer. However, this war caused God to lose faith in the angels and prefer humanity instead.
Temozarela, bitter at this, took twelve angels who felt the same way as he did to Earth to prove to God how flawed humans are. To do this he set up a cult to him and his angels which involved human sacrifice. However, this only made God angry and caused Temozarela to be banished to earth and imprisoned.
Temozarela persuaded a vulnerable Vascar de Guillon to let himself be possessed by Temozarela. 100 years later Temozarela then tried to seduce Betheal, but Betheal resists and eventually imprisons both himself and Temozarela in the Domas Porada. At the end of the 6th Volume, we see the flashbacks of the past where Temozarela is freed from the Domas Porada and in the 7th Volume where Temozarela notices his weakened state (likely due to being imprisoned). He and Belial skirmish which results in Temozarela's body being horribly incinerated, yet he is saved from death by several of his Dark Apostles, consisting of Netraphim, Achmode, and Armand, and taken away to be fully restored. At the end of Volume 7 he is left as little more than a blasted skeleton with barely any flesh left on the bones, yet still alive.
He next appears at Achmode's death in volume 10, where he projects an image of himself from his castle to Achmode's and declares his displeasment at Achmode's treachery. While not taking any major actions since, he appears at various times in the story to communicate with various characters through a circle on a floor that depicts the circle of sabbath. He also seems to have gained more strength since volume 7 in the way he is no longer constrained to his seat where he was previously seen regenerating by absorbing helpless victims' energies in Volume 3.
