Change Guy. When a nerd trades bodies with the toughest guy in school, it's nature vs. nurture! Tuji and Usoo had ... their bodies swapped! After becoming the subjects of an experiment by a mad scientist with its new invention the quantum teleporter-their bodies are reversed, leaving their minds and spirits intact only. Usoo, who once was a model student, must face Tuji's life, a danger to teenagers. Never having an adversary in his life, now he has to contend with the handful of Tuji's list, but can his childlike, gentler attitude fend off his opponents? Or does survival describe a future for him? Will he become the stubborn warrior that suits his current exterior?
