Elayne Harris is a thief, a skilful one. The crazy idea of gifting herself something even monsters haven't thought of pops up in her head one day, and she dedices to gift herself the sacred ring of Diabolo as a present for her twenty-eight birthday. Really, it's the unthinkable. She's perfect, and leaves little to the imagination after every deal. Turns out there's a first time for everything. Alessio Fiorentino can carve out your eyes if you're ever caught stealing from him. He'll place you on a platter, chop off your head and record it if he's the ones who's caught you. When a sentinel of his catches a woman trying to steal the L'anello sacro del Diabolo, he looses his shit, but he looses his shit the more when said thief is brought to him. One look at the thief with braces lacing her white teeth, and glasses seated comfortably on her nose, and Alessio knows she'd be of so much use to him.
