Ruby Kwee is the 11 year old sister of Tina Kwee. Despite her young age Ruby has been skipped ahead several grades and is currently in 10th grade, and was recommended to university by her favourite teacher, Mr. Rousseau.

Along with a few other geniuses, including the "Tech Nerd", Nadene and Irwin Dexter, formed the "Genius Club": an organisation dedicated to making sure the Cleaners do not go haywire again.
