Cathy Katherine

Kathy is a character appearing in Yu-Gi-Oh! ZEXAL.

Design
Kathy, like her nickname has the appearance of a cat. She has two pieces of hair held up by clips which give her the apperance of having cat ears. She also wears the same outfit that Kotori Mizuki wears as they attend the same High School. She also features a pair of huge glasses which are similar to that of Carly Nagisa.

Personality
Kathy is a generally quiet person, who throughout the current duration of ZEXAL has only been seen "stalking" Yuma and his friends. She is also seen in the opening staring at Yuma and his friends from behind a tree. When Yuma attempts to swim the length of the swimming pool without breathing, she is seen in the crowd of students who are laughing at Yuma, but she along with Kotori are the only ones not laughing. She was also seen when Yuma challenged Ryoga Kamishiro to a duel in the central park, and she most likely is observing the duel too.
