Sin Archbishop From Common Place To World's Strongest

One day you get Isekai'd into the world of Arifureta with the power of the Witches of Sin from Re:Zero. ------ [First 12 chapters are very cringe so just bare with it or you can skip them] [Just to be clear this is not a story where 'Regulus’ takes the spotlight and outshines the Original MC, yea he will have his moments but it's mainly 'Regulus’ just tagging along as a Secondary MC, so don't expect him to lead the way or anything.] (I do not Own Arifureta / Re:Zero) (Story Belongs To: Aleiisekai (On Wattpad)) (I have permission to Repost and Edit this story)
