Status and Power: As she carries the blood of Hell's royalty, she technically possesses immense power, but she does not flaunt it, instead struggling toward her dreams as an ordinary girl. While others sometimes mock her for being a bit scatterbrained, she shows growth by moving the hearts of those around her throughout the story. There is a meaningful moment where Vox asks Charlie, "Do you think I could be rehabilitated too?" suggesting their relationship isn't just one of simple antagonism, but something deeper.

Afterward, Vox shows his cold-hearted nature by attempting to discard Angel as "useless."

Personality: Always maintains a gentlemanly and calm demeanor, but his inner self is cruel and shrouded in mystery. He has a sadistic side that enjoys the suffering and chaos of others.
