Episode 15

End of Term Time is the fifteenth episode of the Assassination Classroom anime series. The episode is scheduled to air on May 1, 2015.

Overview
As Class E studies for the upcoming end-of-term finals, the Five Virtuosos, led by Gakushū Asano, is on their case. With a bet in which the class with highest grades in five subjects gets to request anything from the losing class on the line, each group studies hard for that fateful day.

Summary
The final exams is almost upon the school and Korosensei busies himself preparing Class E for it. Having got the basics down from the mid-terms, Korosensei does not wish for all the class to get into the top 50. Instead he motivates them with a goal: whoever reaches the top spot in any of the subjects gets the right to shoot off one of Korosensei's tentacles. As Shiro previously demonstrated, each tentacle that is cut decreases Korosensei's speed by 10%, making it easier for the class to kill him.

Sugino receives a call from Shindo who tells them that in order for E Class to return to the main campus (or in their case, make it easier for the class to kill their teacher) they have to beat the Five Virtuosos of Class A, led by the charismatic Gakushū Asano, the chairman's only son. Meanwhile Karasuma and Irina are given reassurance from the chairman that he will not resort to petty tricks like in the last mid-terms. Asano himself rallies Class A to study hard but also wishes to discover the truth behind the rumours of Class E's mysterious teacher, wanting to use the information to blackmail his father.

Yuma Isogai invites Nagisa and Kaede Kayano to join him, Rio Nakamura, Yukiko Kanzaki and Manami Okuda for a study session in the main campus library. At the library they are confronted by the Five Virtuoses sans Asano. The five attempt to intimidate the group, one trying to flirt with Kanzaki (which Nagisa and Kayano comment that she has the worst luck in men) and another confronting Okuda standing up for Class E. The latter realises that Kanzaki, Nakamura, Isogai and Okuda are ranked quite highly in Japanese, English, Social Studies and Science respectively from the mid-terms. Seeing their potential, the Five make a hasty bet that whoever wins gets to order the losers around. When one comments that they are willing to put their lives on the line however, Nagisa, Kanzaki, Isogai and Nakamura each point the sharp end of their pencils at their intimidators' throats and eye. Nagisa comments that they should not be so quick to offer their lives as the Virtuosos make their exit.

The Virtuosos report the deal to Asano. He sees that this could work for Class A as motivation and quickly types up a contract for Classes A and E to sign. Whoever wins has one request to order the losers around, which comes with 50 other clauses. Asano motivates Class A further but for him, one clause states that Class E must answer any question truthfully if Class A wins. This would allow him to find out about their mysterious teacher and control his father. The night before the exam, the principal supervises the exam writers, who come up with questions that even Class A will have a hard time to solve.

On the morning before the exam, Nakamura and Nagisa are among the first to arrive. When they enter their exam room they discover a Ritsu proxy. Karasuma explains that an AI could not take part and had to humiliatingly seek the principal's permission to allow a substitute to fill in for Ritsu. He does however wish the two good luck as the whole school begin their exams.
