Regulus Corneas is the Witch Cult's Sin Archbishop of Greed. He is the most infamous Sin Archbishop alongside
Sloth, as he is the strongest within the cult and the scale of his rare attacks are devastating.
Regulus was born over a century ago to a poor family, consistenting of his father, his mother, and his two brothers. Regulus hated his family because although they were flawed people, they all tried to be kind to Regulus, which he only saw as pity. Regulus was eventually approached by the Witch Cult and chosen by the Greed Witch Factor, which he accepted alongside the position of Sin Archbishop of Greed. With his newfound Authority of Greed, Regulus killed his entire family for pitying him, killed everyone in his village who had ever looked at him with contempt, destroyed the town that had forced him into such a village, and finally destroyed the country that overlooked the issues in these towns. When he was satisfied, he married a girl from his childhood after killing her family, taking her as his first wife.
Despite his efforts to make her happy, his wife never spoke to him, smiled, or expressed herself. It was only when she killed herself that she finally smiled, being freed from her marriage and knowing Regulus would end up alone– leaving a scar upon Regulus' heart. After making her grave, Regulus began marrying any virgin woman whose face took his fancy, using his Authority to force them to submit; his wives were forbidden from smiling, could not speak unless spoken to, and were always at risk of being killed for upsetting Regulus. The number of wives he took numbered 291 in the modern day, although only 53 are alive today, the rest having been killed by Regulus over various trivial matters.
