Caine is depicted as a nonsensical, over-the-top, vivacious ringleader. However, there is an aloofness about him and a significant disconnection towards the traumatic events that the characters around him are experiencing. Despite Caine's penchant for taking humans captive and tormenting them through hilariously deadly circus games and tricks, he is not actually outright evil, but rather just obliviously mischievous. He is the younger brother of Aria, the magician of the circus.
