Sent by the Elders to put Satoru Gojo on a leash, former rogue sorcerer, Ren Kuryu, specializes in the art of the lure. She has the only power in existence that can drop his Infinity, forcing a terrifying intimacy on a man who has never been touched. As Satoru tries to break her spirit, he realizes she is playing a deeper game—and the "leash" he hated is the only thing he now craves.
