Cathy, Miss Smith, Blondie, Space Girl, Rhapsodian

Cathy is a cheerful girl and can sometimes seem childish. She possesses great innocence and dislikes using force unless absolutely necessary. She is very sweet and enthusiastic. In the early chapters, she displays this great enthusiasm even for the smallest details of life on Earth. She strives to be an Earthling and follow the planet's completely normal customs. She enjoys having fun with her friends and being a "normal" Earthling. Cathy has a positive attitude and always tries to make others smile. She also works very hard to achieve her goals. She has been considered irresponsible and always looking for trouble, which is why Principal Rollins occasionally reports her to her office.
