Assassination Classroom is a shonen anime about a teacher who starts working in a class of, well, academically challenged students. The teacher is an octopus called Koro Sensei who instills in his students some unconventional teaching methods.
Anime like Assassination Classroom, shares the same insane similarities ranging from struggling students to superpowered teenagers tasked with ruthless assassinations. What I especially like about such shonen animes is the development that the characters go through. The students of class 3-E of Kunugigaoka Middle Schoo are not depressing and vicious, but they have obviously lost all motivation. But, now they have a new mission to fulfill: the fate of the world rests on their shoulders.
Koro Sensei is perhaps the most dominant character, but the protagonist of the series is a shy student named Nagisa, and through his eyes, we experience the story. Ansatsu Kyoushitsu is a show that is defiantly worthy of praise because of its vast storyline which is tragic and humorous at the same time. Although the vibe of Assassination Classroom is irreplaceable, I believe the 15 animes I picked for this list share some similar themes that made this anime such an epic show.
15/15. Medaka Kurokami (Medaka Box)
Teenagers tend to have a goal to make other people happy. Although it is quite a noble goal, things don’t always go as planned. Unfortunately, people with ill intentions and self-interest are always there to take advantage of their innocent thinking.
Medaka Kurokami is a purple hair teenage high schoolgirl at Hakoniwa Academy. She became popular due to her charismatic personality. After heroically winning the student council election, She sets up Medaka Box, where students can put their requests for help. However, this seemingly good deed might lead to the demise of the academy and innocent students.
Medaka Box features students playing around with underhanded tactics like Assassination Classroom. Both of these animes also have insane classroom atmospheres.
14/15. Majin Tantei Nougami Neuro (Neuro: Supernatural Detective)
Most of the mysteries lurking in this world are beyond the reach of humans. People cannot help but fandom the origin of these mysteries. However, things begin to change when a young girl begins to solve these mysteries easily.
Yako Katsuragi is an ordinary high school girl with detective skills. Even the most complicated cases are a piece of cake for her.
Yako’s secret weapon turns out to be Neuro Nougami, a demon with supernatural abilities. She strives to solve the mystery behind her father’s death with the help of Neuro.
Majin Tantei features intriguing mysteries about characters with a touch of humor, just like Assassination Classroom.
13/15. Soul Eater
Set in a world where evil spirits and beings run free live death gods, who train themselves continuously to fight off these evil spirits and witches. They must eat the souls of evils to maintain peace in the city.

Soul Eater features similar themes of struggling students with a hectic life. One is focused on students who want to control their abilities rather than assassinate their teacher.
12/15. Hidan no Aria (Aria the Scarlet Ammo)
The city of Japan became a high crime zone that led to the formation of an elite academy by the government. The academy produced intelligent armed detectives known as Butei to decrease the crime rate in the city.
Kinji Tooyama is a guy with an introverted personality. He once served in the combat division as a talented Butei. However, Kinji dropped out of the academy for various reasons. His fateful encounter with Aria Holmes compelled him to return to the academy. Now, both of them must work together to protect the city while learning more about each other.
Hidan no Aria features armed students tasked with eliminating their targets, which is quite similar to the premise of Assassination Classroom.
11/15. Darker than Black: Kuro no Keiyakusha
Set in a world where the emergence of gates disrupted the physics of the world. People who lost their sanity in exchange for powers end up becoming ruthless assassins under the name of Contractors.

This anime follows the story of a crazy teacher and his unusual students. Most of the moments featured in this anime are sarcastic which gives unique vibes and experience to viewers.

The students and teachers in both shows are hilarious and relatable to each other.
9/15. Munou na Nana (Talentless Nana)
Set in a world where unknown creatures called enemies of humanity appeared out of nowhere to create chaos.
The government creates an academy on a remote island to train teenagers with powerful abilities to fight off these creatures. Nana Hiiragi is a cheerful young girl who transfers to the special academy made for gifted teenagers. She quickly becomes friends with all the students. However, strange incidents begin to occur right after her debut.
Even though both shows are dark animes about the assassination, Ansatsu Kyoushitsu has a more lively vibe and focuses more on comedy.

The story of this anime revolves around orphans living in an orphanage called Grace Field House situated in a far-off place. This place was a little paradise for these innocent souls until a gruesome truth about the place surfaced.

7/15. The Disastrous Life of Saiki K. (Yakusoku no Neverland )
Supernatural abilities might be a blessing for everyone, but Kusuo Saiki considers his wide range of abilities nothing but a curse. All the students are head over heels to witness his powers.

6/15. Danganronpa: Kibou no Gakuen to Zetsubou no Koukousei
The story of this dark anime revolves around students and the changes in their life brought about by their enrollment in a prestigious academy.

However, his happiness soon turns into despair as he finds out that the academy has a tragic play in place in which only one will prevail.
It is quite similar to Assassination Classroom with a little different setting the only difference is students fight each other to survive while the teacher enjoys the show. However, Dangaronpa only makes sense if you have played the games, and I must say the game is much better!
5/15. Angel Beats!
Angel Beats! follows the story of deceased individuals and their life in another world called After Life. Most of the individuals in this world are teenagers who find themselves in this world after experiencing tragic deaths.

However, Shigeo cannot control the sensitive emotions that can cause him to go berserk. With this dire situation in hand, What will be the Mob’s course of action?
Mob Psycho 100 is an anime like Assassination Classroom in the sense that it features an overpowered main character, and both protagonists are shy and insecure boys who shine into leadership positions.
3/15. Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu e (Classroom of the Elite)
Classroom of the Elite is an ecchi harem anime that follows the story of students of D-Class and their struggle to reach the A-Class for a better future and life. Kiyotaka Ayanokouji is an aloof guy who got enrolled in the prestigious Koudo Ikusei Senior High School.

Ryuko wins the match by using the power of Scissor Blade and Senketsu (Battle Armor). Now, she must fight against the top dogs of the academy to unveil her long-desired answers.
Kill la Kill despite having some differences, share strong characters who undergo intense events. Both animes are full of Imagination and strange settings, but without being silly. Both series are also perfect for people who love a bit of fun in their dark anime.
In short. If you liked one, I am sure you will like the other.

Both anime feature teachers with revolutionary teaching styles. And of course, the students in the series do not make it easy for their teachers to handle them. But in Assassination Classroom, unlike GTO, students try to murder their teacher (long live the small difference).
