Anime fans, action-comedy lovers, and those who are impressed by assassins found a common interest in 2015 when the anime adaptation of Yusei Matsui's manga series, Assassination Classroom, was released. Even though the series came to a bittersweet end in 2016, it remains in the hearts of viewers everywhere to this day.
While the wild antics, complex plot, and lovable characters made it enjoyable, many would agree that the intricate assassination attempts made by Class 3-E were the best part of the series. The protagonist, Nagisa Shiota, and his classmates crafted several plans to kill Koro-Sensei, who not only was their target but also their homeroom teacher. Although every attempt made to exterminate Koro-Sensei was equally entertaining, some attempts stood out and were surprisingly more impressive than the rest.
10 Koro-Sensei Dodged Tomohito's Deadly Fast Ball
One of the first advanced attempts to assassinate Koro-Sensei occurred during the episode titled "Baseball Time." Nagisa Shiota and baseball prodigy, Tomohito Sugino, hatched a plan to use Tomohito's skills to successfully land a fatal hit on their teacher.
Knowing that Koro-Sensei was isolated, relaxed, and preoccupied with catching up on the latest stories in the newspaper, Tomohito threw a baseball pierced with Anti-Sensei Bullets directly at his head. Koro-Sensei reacted quickly and easily caught it with a baseball glove before it was able to reach him.
9 Karma Risked His Life & Forced Koro-Sensei To Make The Ultimate Decision
Karma Akabane was especially ruthless in his attempt to kill Koro-Sensei. In the episode "Karma Time," Karma immediately noticed Koro-Sensei's soft-hearted nature and realized that his new homeroom teacher would do any and everything to protect the students in Class 3-E.
Using Koro-Sensei's biggest weakness against him, Karma jumped off a cliff with a gun loaded with Anti-Sensei Bullets in hand. Koro-Sensei found a way to save Karma's life without getting injured, leaving Karma with no choice but to develop a newfound respect for him.
8 A Mission To Assassinate Disguised As A Fun-Filled School Field Trip
As the students in Class 3-E prepared for the first field trip to Kyoto in the episode "School Trip Time/1st Period," they mapped out a detailed plan to use the long list of trip activities to their advantage. While the students were looking forward to enjoying the festivities of the trip, they also remained focused on keeping Koro-Sensei distracted and blinded by the fun.
The group traveled with their teacher and guided him to the various assassination landmarks, but their plan fell through when they were unexpectedly ambushed by a gang of delinquent upperclassmen.
7 The Deadliest Artificial Intelligence Transferred Into Class 3-E
When the students in Class 3-E seemingly came to a standstill in their journey to find new ways to assassinate Koro-Sensei, an artificial intelligence robot, also known as Autonomous Intelligence Fixed Artillery, was added to their class roster in the episode "Transfer Student Time."
Shortly after arriving, the new transfer student began firing rounds of Anti-Sensei Bullets after calculating the most effective and efficient ways to shoot Koro-Sensei. Although the student successfully hit Koro-Sensei's fingertip, their attempts were quickly halted when the other students complained about the distraction, leading Koro-Sensei to reprogram the student to be a good team player.
6 Ryoma's Treacherous Actions Led To A Dangerous Day At The Pool
Through observation in the episode "Vision Time," the students learned that one of Koro-Sensei's biggest weaknesses was water. Ryoma Terasaka, a student who felt particularly betrayed by his peers, sought out help from Shiro and Itona Horibe, a villainous duo who had a well-thought-out plan of attack with ulterior motives.
After luring Koro-Sensei and his classmates to a pool, Ryoma set off a transmitter as a signal, but unknowingly triggered an explosion that put Class 3-E in danger, serving as bait for Koro-Sensei to enter the water. With help from his classmates, Ryoma was able to save the day and Koro-Sensei survived.
5 Koro-Sensei's Obsession With Crude Content Nearly Led Him To His Demise
While the rest of his classmates were busy bug hunting in the episode "Island Time," Taiga Okajima was focused on carrying out his plan to catch Koro-Sensei in a fatal trap. By secretly observing Koro-Sensei for months on end, Taiga learned that his teacher had an affinity for adult magazines.
Taiga orchestrated a scheme that would use Koro-Sensei's lewd habits against him by enticing him with a pile of his favorite content that secretly covered a pit full of Anti-Sensei weaponry. However, his plan was spoiled when Class 3-E biologist, Hinano Kurahashi, blew his cover by expressing excitement when Koro-Sensei happened upon a rare and valuable beetle.
4 The On-Sea Chapel Quickly Became A Death Trap
Using a chapel placed in the sea surrounding Okinawa Island Resort, Class 3-E managed to trap Koro-Sensei in the episode "Action Time." With nowhere to go, Koro-Sensei was forced to watch a film edited by his student Koki Mimura, which served as a distraction for the rising water level in the chapel.
The students then shot off seven of his tentacles and encased him in a hydraulic cage. Rendered helpless, Koro-Sensei was left to the mercy of Ryunosuka Chiba and Rinka Hayami, who had their sniper rifles aimed directly at him. However, with the use of his ultimate defense, Koro-Sensei was able to evade death once more.
3 Kaeda & Her Classmates Made A Colossal Caramel Pudding With Explosives Hidden Inside
News of a surplus of eggs led Kaeda Kayano to come up with a plan to assassinate Koro-Sensei in the episode "Kaeda Time." Knowing Koro-Sensei's love for food, she and her classmates assembled a giant caramel pudding with a bomb discreetly planted within it.
After the construction was complete, she gifted it to Koro-Sensei, who wasted no time and happily began devouring the humongous dessert. Unfortunately, Koro-Sensei sensed the bomb and was able to disable it before it exploded. He then shared the remainder of the pudding amongst his students and congratulated them on their effort.
2 Kaeda Unleashed Her Lethal Tentacles On Koro-Sensei & Revealed Her True Identity
Out came one of the biggest surprises yet when Kaeda revealed her true identity during the episode "Secret Identity Time." As she, Nagisa, and Koro-Sensei worked together to clean the storage shed, Kaeda caught her teacher by surprise by attacking him with deadly tentacles that emerged from her body.
Her motives were uncovered when she admitted that her real name was Akina Yukimura, and she blamed Koro-Sensei for the death of her sister, the former homeroom teacher for Class 3-E. Knowing the tentacles were life-threatening, Nagisa kissed her and released her from her rage long enough for Koro-Sensei to remove the tentacles and save her.
1 The Final Assassination Attempt Was Simple, Sorrowful, & Successful
The final assassination attempt was one ironically instructed by Koro-Sensei. After a series of complicated events and a long, drawn-out battle, Koro-Sensei was left nearly lifeless with no energy or willpower to defend himself. With death fast approaching, Koro-Sensei encouraged his reluctant students to carry out their mission despite their valiant efforts to save him.
The students unanimously agreed to carry out their responsibilities as assassins and held him down with tears in their eyes as he did his final roll call. Nagisa then dealt the final blow with an Anti-Sensei Knife and killed the homeroom teacher that Class 3-E had come to know and love.
