Claudio originates from Italy and is said to be "the world's strongest exorcist." He leads the organization known as the Archers of Sirius. Claudio is somewhat sarcastic and cocky, as suggested by his intro quotes that see him calling his opponents either amateurs or an easy win, all while flicking his hair. A number of his poses and entrances have dramatic flair to them, suggesting some pride and vanity to him. One of his victory poses suggests that he can be more empathetic and kind, as he lends a hand to his opponent after they lose against him. However, in another instance, he is also shown to slow clap sarcastically.
