Assassination Classroom Episode 16 Recap & Characters (Spoiler-Free)

Episode Summary

School's Out - First Term

Over two days the third-year class takes end-of-term exams. Asano stays first overall and Class A dominates the top ranks, but Nakamura (English), Isogai (social studies) and Okuda (science) take first place, so Class E wins the bet. Karma, who skipped studying, drops to 13th, and Korosensei deliberately lets him taste defeat.

With four students also tied for first in Home Economics, Korosensei must grant the right to destroy seven tentacles. The class will use that right on the resort island in Okinawa it receives as its reward, and Korosensei declares the first semester over.

• Exam and results

  Students sit the exams, with Nakamura and Nagisa solving a question easily. Korosensei announces results where Asano stays first and Class A holds six top spots, while Karma drops from 4th to 13th after his arrogance.

• Tentacle prize and Home Economics loophole

  Class E takes three top spots, earning the right to destroy three tentacles. Terasaka and three others then reveal a tie for first in Home Economics, arguing nobody specified which five subjects counted, so Korosensei must grant seven tentacles; the class saves that right for the island assassination.

• Closing ceremony and reward

  At the closing ceremony Class E confronts Asano and the Big Five over their prize. Class A mocks the Big Five's loss, Asano vows revenge, and Class E's reward is a holiday resort on a tiny Okinawa island, which becomes the site of the planned assassination.

Recent Timeline

• Takaoka dismissed after knife challenge (Episode 13)

  Takaoka, who had taken over PE with violent training, proposed a duel in which a student would face him with a real knife while he stayed unarmed. Nagisa defeated him and pinned him with the blade at his throat. Chairman Asano then dismissed Takaoka for ruling by violence and fear, reminding him that the Ministry of Defense has no say over the school's teachers.

• Pool dam trap ambush (Episode 14)

  Terasaka fired the signal gun Shiro had given him, setting off an explosion that destroyed the pool dam and swept the class toward a cliff until Korosensei saved them all. In Karma's counter-plan Terasaka took Itona's blow, and the smoke-tainted shirt and the class's splashing weakened Itona until Shiro admitted defeat. Terasaka became the class's ally.

• Library bet with Class A Big Five (Episode 15)

  At the main campus library, the Big Five picked on Isogai's study group of Nagisa, Kayano, Nakamura, Kanzaki and Okuda and made a hasty bet that the winner would order the losers around. When one of them said he would stake his life on it, Nagisa, Kanzaki and Nakamura pointed their pencils at the taunters' throats and eyes. Gakushu Asano turned the bet into a contract for both classes with 50 other clauses, including one requiring Class E to answer any question truthfully if Class A won.

• Final exam results: Class E wins the bet (Episode 16)

  Asano kept first place overall and Class A held the top six spots, but Class E took first in English, social studies and science, winning the bet three subjects to two, and Asano was rebuked by his father. Karma dropped from fourth to thirteenth due to laziness and arrogance, and Korosensei's rebuke drove him away in despair, which prompted Karasuma to question Korosensei's approach.

• Home Economics tentacle claim and semester end (Episode 16)

  Terasaka, Hazama, Yoshida and Muramatsu, tied for first in Home Economics, claimed one tentacle each, so Korosensei had to grant the right to destroy seven tentacles in all. At the closing ceremony Class E confronted Asano and the Big Five to collect the prize, a holiday resort on a tiny Okinawa island, where the class will use the tentacle right. The Chairman privately resolved to restore the old order over the summer, and Korosensei declared the first semester over.

  His teacher and target; exploiting the fact that nobody had said which five subjects counted, he won the right to shoot one of his tentacles by tying for first in Home Economics.

World Memo

• Crescent moon and the destruction of Earth

  At the start of the students' third year the moon suddenly exploded into a permanent crescent. The creature responsible has declared that he will destroy Earth next March in the same way, a standing threat that frames the assassination.

• Government-sanctioned assassination and reward

  The government reluctantly accepted the creature's own offer to teach Class 3-E on condition that he harms no students, and secretly tasked the class with killing him, since public knowledge would cause global panic. A successful assassination is rewarded with 10 billion yen.

• Anti-sensei weapons

  The government developed anti-sensei BBs and knives that are harmless to humans but break down the creature's cells, and supplies them to the students.

• Class E's place in the school system

  Kunugigaoka's Class E is sent every day to an isolated mountaintop campus and discriminated against as the lowest-ranked class, nicknamed the E-as-in-End Class. The chairman deliberately keeps it at the bottom in grades and treatment so that fear of falling into it drives the other students. To escape, a student must rank in the top 50 of the 186 third-years and get permission from their former homeroom teacher.

• Final-exam tentacle prize

  Each student who topped a subject in the finals earned the right to shoot off one of Korosensei's tentacles. With three subject wins plus four students tied for first in Home Economics, Class E holds the right to destroy seven tentacles and will use it in the island assassination. Each lost tentacle cuts his speed by 10%.

• Final exam bet between Class A and Class E

  Under the bet, the class that took more of the five subjects could give the loser one order. Class E won with three subjects and claimed a holiday resort on a tiny island in Okinawa as its prize.

• Home Economics exam autonomy

  Home Economics teachers have the freedom to create their own exams, separate from the standard exam format.

Clue Board

• Vague answer on the punishment (Episode 4)

  Nagisa grows suspicious after Korosensei's punishment of Irina, and Korosensei gives only a vague answer when asked for clarification, leaving the reason open.

• The chairman's words (Episode 6)

  The chairman, briefed by the Ministry of Defense, calls Korosensei a sad being who meant to become the world's savior but ended up a great evil that will destroy it. What else he knows is not shown.

• Korosensei's past romances (Episode 8)

  Karasuma started to ask whether Korosensei's romances dated from a time when he had two arms and two legs, then let it drop. What Korosensei used to look like is still unexplained.

• Shiro and Itona's score over the moon (Episode 10)

• Claimed brotherhood with Itona (Episode 11)

  Shiro insists Itona and Korosensei are brothers despite different parents and upbringings, and the fight is presented as proof. Korosensei says he was raised as an only child and does not know what Itona means. The relation is unresolved.

• Source of Itona's tentacles (Episode 11)

  Itona has tentacles like Korosensei's growing from his hair. Korosensei demands to know where they came from, but Shiro refuses to answer, so the origin stays unexplained.

• Reason for current form and teaching Class E (Episode 11)

  Students ask why Korosensei takes his current form and why he teaches Class E. He answers seriously that they must earn these answers by trying to kill him, so the reason remains hidden.

• Another critical weakness of Korosensei (Episode 14)

  A further weakness of Korosensei surfaced during the pool assault, described as far more important than his inability to swim. The class did not realize it at the time, and its nature is not revealed.

Deduction Board

Facts

• Three subject wins

  Nakamura took English with 100, Isogai social studies with 97 and Okuda science with 98, so Class E won three of the five subjects and the bet with Class A.

• Seven-tentacle right granted

  After four students tied for first in Home Economics claimed one tentacle each, Korosensei was talked into granting the right to destroy seven tentacles; the class will use it on the island.

• Karma's drop

  Karma, fourth in the midterms, slacked off and counted on luck, and fell to 13th overall.

Evidence

• Relieved to lose only three

  Korosensei privately thought losing three tentacles would be manageable but six would have been truly dangerous, showing he counts tentacle loss as a real threat.

• Home Economics tie

  Terasaka, Hazama, Yoshida and Muramatsu tied for first in Home Economics and, arguing nobody had said which five subjects counted, each claimed a tentacle.

• Class A holds the top

  Gakushu Asano kept first place overall and Class A took all of the top six spots; Class E's best overall were Kataoka and Takebayashi, tied for seventh.

Inferences

• Tentacle loss weakens Korosensei

  Losing tentacles reduces Korosensei's strength, so the tentacle-destruction rights won in the exams give the class a real advantage.

• Why he pushed Karma

  Korosensei believes the talented Karma must taste a crushing loss and learn from it instead of relying on easy wins, so he rebuked him on purpose; Karasuma questioned the approach.

• The island as the stage

  The holiday resort on a tiny Okinawa island that Class E chose as its prize becomes the stage for the big assassination using the seven-tentacle right.

Suspicions

• Another unnamed weakness

  Nagisa's narration says another weakness of Korosensei came up that day, more important than his inability to swim, but what it is has not been revealed yet.

• Asano's vow of revenge

  Gakushu Asano, scolded by his father after losing the bet, swore revenge on Class E. How he will strike back is still unknown.

• The Chairman's plan to restore order

  The Chairman intends to take measures after the summer holidays to restore the old order. What he will do is not yet known.

Battle Record

Terasaka, Hazama, Yoshida and Muramatsu, who tied for first in Home Economics, claimed one tentacle each, and Karma's remark at Chiba's prompt led the class to talk Korosensei into granting the right to destroy seven tentacles.
