I recommend "Dimensional Witch from Zero" to you. The main character of this book was a Super Plane Archmage. When she was beaten until only a trace of her soul was left, she devoured a mortal's soul and occupied her body, becoming a Dimensional Witch. In this novel, the protagonist can control and occupy other people's bodies at will, which meets your needs. I hope you like my recommendation, Mwah ~😗
