When Middleton High School participates in a student exchange program, Ron is selected to go to a school in Japan while a student named Hirotaka is chosen to come to Middleton. Ron finds out that the school he was assigned to visit is a secret ninja school while Kim and Monique eventually start crushing on Hirotaka. However, when Lord Monkey Fist steals the Lotus Blade from Ron’s sensei, it’s up to Ron to save the day; though without Kim’s help.

Kim, hoping not to be landed with Ron as her science project partner, instead gets a brainiac who won’t let her do anything at all. Monique gets Ron and quickly becomes exasperated by his trademark laziness. Meanwhile Drakken charms DNAmy into creating a vicious Komodo dragon.

Ron steals Kim's supersuit to use in the upcoming football game. Meanwhile, Professor Dementor becomes jealous of the suit and devises a system to control it.
