He will use any means to achieve his goals, not hesitating to sacrifice his companions. He goes beyond being just a "jerk" and could be described as a total scoundrel. There are patterns where his actions hinder the completion of adventures, but even when things worsen, he never apologizes and instead shifts the blame onto the victims. Naturally, due to this personality, trust from the circus members is extremely low. However, he is also childish and sarcastic; when he cannot get his way due to clear rules or when he is attacked, he ignores his own actions and is the first to criticize others.

Kind and an optimist. Her cooperative attitude stands out, as she offers help to struggling members and encourages everyone to enjoy the adventure together. It is unclear if she lacks a full sense of pain or is just very stoic, but even when facing crises—like being stabbed with a knife, slammed into walls, or pierced by spikes—she tries her best to act brave. It is speculated that this devoted, positive personality and excessively cooperative attitude stem from perfectionism or low self-esteem. She tries to ignore bad events, but sometimes her anxiety, fear, and frustration leak out.
