For the students of Class E in Assassination Classroom, school activities are very different from the other classes. These kids are being trained to assassinate an alien that shockingly became their teacher. The students in this low-ranking class are treated like dirt by the rest of the school, which is especially tragic due to how each has a unique personality that brings something important to the world they live in.
People who are invested in learning about people's personalities are often drawn to the Zodiac, which assigns qualities to someone based on their star sign. These qualities have a lot of parallels with those of this show's characters.
12 Aries: Karma
Aries like to put their all into everything that they do, even at the risk of making rash decisions. Karma is the edgiest member of Class E, and his affinity for violence and blazing confidence make him a good match for the Aries sign.
He marches to the beat of his own drum and doesn't waste time with situations that don't seem interesting or concern him. His confidence can sometimes get the best of him, however, as seen when he fails an exam after refusing to study.
11 Taurus: Megu
Megu is the resident supermodel of her class, but is very humble about her good looks. She's great in her role as the female class representative because of her calm level-headedness, which are traits she shares with the stable, grounded Taurus sign.
Because of her rationality, she's great at keeping the boys of the class in line. She loves to take care of others, but sometimes at her own expense: She was dropped down to Class E because her grades suffered after trying to help a friend study.
10 Gemini: Kaede
Geminis have bright, bubbly personalities, just like the cheerful Kaede. Kaede almost always appears optimistic, and her kind demeanor makes her a good friend to those in her class. She also has a tendency to be passive, however, preferring to go along with what the rest of the class does in terms of assassination attempts on their teacher.
Geminis too can have trouble making strong convictions, and would rather go with the flow of any situation to avoid any unwanted stress.
9 Cancer: Tomohito
Cancers are emotionally charged individuals who believe that being in tune with one's feelings is stronger than any other power in the world. Tomohito is a good match for the sentimental Cancer because of the boy's compassion for the others in his class.
He is one of Nagisa's closest friends, and everyone around him feels their moods lifted by the positive energy he gives off. At the same time, he's very caught up in his past. He loves to play baseball and deeply misses being on his school's team, and is open about these feelings to those who care about him.
8 Leo: Karasuma
Karasuma is a secret agent who watches over the class assassination attempts under the guise of being the gym teacher. His suit and his sharp, serious expression give him the air of a leader. Leos love to look for justice in the world, and often take on the role of becoming a hero to save what is important to them.
Karasuma's commitment both to his job as an agent protecting the world from an alien and as a teacher making the next generation stronger shows that he would be a good Leo.
7 Virgo: Itona
Itona is one of the few transfer students into Class E. He was abandoned and bullied as a young child, which made him vengeful and determined to become stronger. Like a Virgo, Itona sets out to do what he needs to and isn't satisfied until the job is done well.
At first, he is independent and self-centered, but he slowly becomes a team player when he spends more time in his new class. Also like a Virgo, Itona can be very blunt when it comes to giving his opinion. He never sugarcoats his words, preferring to go the route of brutal honesty.
6 Libra: Rio
Though she was once a child prodigy, Rio trashed her school career in the search of finding more friends so that she felt less lonely. A Libra might relate to this situation, as this sign is primarily focused on social life and relies on good friends to be truly happy.
Rio has a rather mischievous personality and is great at brutally teasing her friends. A Libra's energy makes them the best to have at parties, and Rio is no different with her talent at starting gossip sessions with the other girls in her class.
5 Scorpio: Kirara
Scorpios are people who love to lead a life of mystery by keeping their incredible knowledge to themselves until they can use it to their advantage. Kirara is one of the quietest people in her class and loves to learn all she can through reading. Her favorite story genre is horror, and her interest in the macabre extends to her assassination attempts, like when she tries to place a curse on Korosensei.
Scorpios find delight in the dark and moody, too, and their intense demeanor makes them intimidating. Nobody wants a Scorpio to place a curse on them since their energy makes it feel like it may come true.
4 Sagittarius: Korosensei
Sagittarians are thrill-seekers who love to travel and expand their horizons. They have intellects that could rival even a genius extraterrestrial, like Korosensei. Korosensei may intend to destroy the earth, but that doesn't stop him from doing his best to educate the class he teaches.
He understands what people need to hear to grow, and gives sage advice that encourages even the most despairing students of the lowest class level in school. Plus, he's capable of traveling around the world in mere seconds to gain all the cultural experience and adventure that he wants, which is a power any Sagittarian would long for.
3 Capricorn: Manami
Manami is the top scientist of Class E and spends all of her time running experiments, trying to create a poison that could take out Korosensei. She is very shy and introverted, but this is mostly due to her lack of ability to speak her mind clearly. She admits to finding emotions frivolous and prefers the language of science formulas over spoken conversation.
Because of this, Manami makes a great match for the stoic, serious Capricorn sign. Capricorns are rational people who prefer to spend their time improving their intellects instead of worrying about illogical, trivial situations.
2 Aquarius: Ritsu
Aquarians often have trouble displaying their emotions in a way that others can comprehend. They are incredibly smart, but their minds work differently from any other sign. This can often make them seem cold or detached.
Ritsu is undoubtedly cold and detached when she first transfers to Class E, the reason being that she is a computer. She's a system originally designed to kill Korosensei on the spot. After some updates, however, she becomes able to express emotion, and seems delighted by the fact. With close friends who understand their divergent trains of thought, Aquarians can also express their creativity more freely.
1 Pisces: Nagisa
Pisces often fall into the category of being a mix of different qualities from each sign. Because of this, they often can stay in the background of situations due to their ability to blend in with any crowd. This quality is also Nagisa's special trait, as he can become so undetectable that he can easily sneak up on others to attack.
Pisces are contemplative and love to dream big, which is reflected in how Nagisa narrates the show, giving his observations and conclusions as he experiences the bizarre life he leads at school.
