Koro Sensei and his students try some matchmaking at the end of their island trip. Class 3-E's eventful summer ends with a taste of pure festival fun.

Kaede comes up with a delicious plan of attack, Class 3-E plays an intense game of Cops and Robbers, and Koro Sensei is accused of a serious crime.

Koro Sensei faces off against the powerful, tentacled Itona and his handler Shiro yet again, revealing more of his teaching philosophy along the way.

Itona endears himself to the boys in Class 3-E as he shows off his assassination creation. The students call each other code names for an entire day.

Competition between the elite A Class and downtrodden E Class heats up at the school sports festival, with Isogai's livelihood hanging in the balance.

After an accident, the E Class winds up doing a whole different kind of studying off campus. But will they have a chance to bone up for the midterms?

A well-intentioned act leads to a falling-out with Professor Bitch. Soon the E Class finds itself facing off alone against a formidable assassin foe.

When Koro Sensei and Mr. Karasuma reach the Reaper's hideout, it's anyone's guess who'll come out on top--especially with wild-card Irina in the mix.
