Olba Meyer (オルバ・メイヤー Oruba Meiyā) is a rogue Archbishop of the Church of Ente Isla. He betrayed Emilia and temporarily joined forces with Lucifer to kill Emilia and Satan. Following his failed plans, he went into hiding.
When Emi was a child, he was the one who took Emi and trained her to defeat the Demon Lord. He had been working with the corrupt Church of Ente Isla to kill any and all of their enemies, especially the rebelling 'heretics' such as those of the Allied Knights Order and anyone affiliated with them. He was Crestia's superior and would frequently give her assignments involving the brutal slaughter of the aforementioned groups of people. Later on, however, it was discovered that he had conspired with Lucifer to annihilate the Hero and the Demon Lord.

- Creation of 'Gates': Not shown directly, but Olba and Lucifer arrived in Japan by using a gate Olba created.
- Energy projectiles: Olba was shown to be able to release many purple projectiles that he can detonate at will.
