Класс убийц, 1-й сезон

Class 3-E prepare for the arrival of their second transfer student, who is allegedly more powerful than Ritsu.

A baseball tournament is to be held, in which Class 3-E are forced to play an exhibition match against the top players of the school's baseball club, which Sugino used to be a part of.

As Karasuma briefly senses what appears to be a fearsome aura coming from Nagisa, Akira Takaoka, an aquaintance of Karasuma from the Ministry of Defense, is sent to Class 3-E to take over Karasuma's role as P.E. teacher.

Koro Sensei exposes a major weakness, and Terasaka interrupts a fun summer day out with an assassination attempt that goes a little too far.

For finals, Koro Sensei gives his class a new goal--with an irresistible reward. The E Class makes its own deal with the top-tier A Class's Big Five.

After two days of exams, the results are in. Both the ace A Class and the end E Class must come to terms with the outcome--and so must Koro Sensei.

The E Class trains intently under a pro killer to prepare for their island assassination. Once there, they must make sure everything falls into place.

The summer assassination attempt is followed by a crisis affecting nearly half the E Class. Can the rest think and move fast enough to save them?

The E Class must put their lessons into practice as they tackle an intimidating hotel brimming with baddies--and all without Koro Sensei's help.

Karma must use his head to get past a formidable foe. Nagisa goes undercover as the E Class continues to sneak its way to the hotel's top floor.

The students take on one last assassin opponent before meeting the shadowy figure who's holding the virus remedy hostage in exhange for Koro Sensei.
