Kendall is usually a tough, bossy and tomboyish young girl, but is a very good and intelligent student. She has very rarely failed a class (one or twice in one 6 months) and is a straight A student who earns mostly the highest marks (A-, A, A+, and even A++) although in "Frame Story" she only manages to earn a D- (51-60) due to Kick's failure at cooking. Sometimes she is really cool and extreme. Kendall is seen as a "convinced-by-herself" girl because of her school life.
