Akame From Akame ga Kill!

Akame appears to be a very serious and cold-hearted anime assassin which stems from her hellish training that the Empire forced her and her sister through, but it is eventually revealed that she is just socially awkward.

She cares about her comrades very much and she is always worried that one of them may not make it out alive due to her first-hand experience that war always has a high mortality rate.

She also tends to hide her emotions when it is revealed that a comrade dies, such as seen with Sheele, making Tatsumi mistakenly and incorrectly assume that she deals with it easily, because she is used to it.

As a child, Suzuya’s personality was somewhat normal, albeit a tad twisted, but as a result of Big Madam’s treatment. He no longer felt fear, pain, nor did he have any morals. Yukinori Shinohara, his mentor, described him as a “problem child”.

Despite his childish and playful demeanor, he was also extremely violent and highly disturbed. He usually described his killing methods to be clean, without needless movements, which is a skill he seemed to take pride in as an anime assassin.

The Scarred Man From Fullmetal Alchemist

Scar is an anime assassin and a survivor of the genocide campaign during the Ishvalan Rebellion. While fighting a State Alchemist named Solf J. Kimblee in the midst of the conflict, Scar lost his right arm as well as his family.

With the last of his strength, his brother had attached his own arm, by means of alchemy, to Scar.

Even if Scar wanted to finally break the Ishvalan teaching and perform transmutation alchemy, he cannot because his right arm is only designed for destroying.

12. Satō From Ajin

Satō From Ajin

Sato is shown to be a calm and cheerful anime assassin on the outside as he’s able to make people feel calm in his presence.

However, beneath this facade is a sinister persona of his – he is merciless when it comes to killing others and he often finds it fun to cause destruction and kill people (whether they’re innocent or not).

He was like this even as a kid when he killed many animals. And when his father beat him as punishment for it, he displayed no sense of guilt and expressed puzzlement on the concept of love and other emotions.

This shows that Sato was already sociopath before he killed people.

11. Thorfinn From Vinland Saga

Thorfinn From Vinland Saga

When the series of this anime assassin begins, Thorfinn is shown as an innocent and friendly anime assassin who is searching for adventure. He shared a very good relationship with his family and enjoyed stories told by Leif about his adventures.

This would become the foundation of Thorfinn’s drive to avenge his father.

10. Kotomine Kirei & Assassin From Fate/stay night & Fate/Zero

Kotomine Kirei & Assassin From Fate/stay night & Fate/Zero

Unknown to all those around him, Kirei was born defective, possessing a warped mind since birth. He is an evil anime assassin, but not a villain. He is deviant, but not inhuman.  Despite his personal accomplishments, he never felt satisfaction.

Despite his best efforts he could not enjoy what other people found happiness in, and instead found himself drawn to negative emotions like the pain of others.

He is able to act like a normal person, even bringing pride to his father, but he intrinsically does not feel the same happiness others do.

He is very similar to Shirou in that he is a void human being without a clear sense of self, and can be called the opposite extreme of Shirou.

9. Himura Kenshin From Rurouni Kenshin: Trust and Betrayal

Himura Kenshin From Rurouni Kenshin Trust and Betrayal 1 1 20 Deadly Anime Assassin Characters

Soft-spoken, serene and humble, this anime assassin got it all Himura Kenshin’s usual demeanor suits his effeminate appearance perfectly.

Always willing to put others before himself, both in terms of well-being and social standing, Kenshin usually refers to others with the noble honorific of “-dono” while nearly always speaking of himself with the particularly humble pronoun “sessha” and ending his phrases with the formal verb “de gozaru“.

He carries himself with an air of amicable temperance, politely conversing with the people he encounters and freely giving his meager services to those who need a hand.

8. Levi Ackerman From Attack on Titan

Levi Ackerman From Attack on Titan

Levi is described as a “clean freak” by those who know him personally as he prefers his environment and himself to be spotlessly clean anime assassin.

He is averse to having either himself or his equipment soiled, and has been known to wipe down his blood-smeared blades while still on the battlefield.

However, he will not hesitate to touch filth if he deems it necessary.

7. Shiki Ryougi From The Garden of Sinners (Kara no Kyoukai)

Shiki Ryougi From The Garden of Sinners

Children born into the anime assassin Ryougi family are generally male and are artificially induced with dual personalities, but Kaname was unable to manifest a second personality of his own.

Shiki was confirmed to display the trait instead and was raised as the family head in his place, displaying the personalities of SHIKI, a male personality customarily called the “yang” personality, and Shiki, the female personality called the “yin” personality.

It is not the result of Dissociative Identity Disorder even though it is a dual personality, so it is more a matter of whose actions take priority.

6. Alucard From Hellsing

Alucard From Hellsing

Alucard fights with ferocity, and often extreme cruelty, rarely shooting to kill until his target has been completely disabled and humiliated.

However, he does have some humanity left in him, as he is still capable of shedding tears and showing affection for those who are dear to him, taken by Alexander Anderson to mean that he is not completely lost anime assassin. As he is essentially immortal and invulnerable, Alucard is very egotistical.

He freely taunts and belittles his opponents, often allowing them to inflict seemingly fatal wounds before healing himself and counterattacking.

One of his favorite methods of fighting is to allow himself to be blown to shreds before simply flowing back together. An example is shown in volume 2 when Alucard fights Luke Valentine.

5. Lelouch vi Britannia From Code Geass

Lelouch vi Britannia From Code Geass

Lelouch is a highly intelligent anime assassin who is also calm, sophisticated, and arrogant due to his aristocratic upbringing. While at school, Lelouch conducts himself as a sociable, likable, and often easygoing student.

Lelouch is known for having a very stoic personality. He never cared about schoolwork, seeing the entire thing as trivial, even though his high intelligence would make it easy for him.

4. Risotto Nero From JoJo’s Bizarre Adventure

Always focused on his goal and carefully approaching Doppio whom he suspected to be Diavolo’s underling, Risotto is methodical in his assassination method, making decisive actions and calmly analyzing Doppio’s moves before acting.

His ability to predict his opponent’s moves is formidable, and has allowed him to almost kill Doppio were he not outsmarted by the Boss.

3. Light Yagami From Death Note

Light is a young man, standing at above average height with light-brown hair and brown eyes. During Part I, when not wearing his school uniform.

During Part II, if not wearing a similar style of clothes, he is seen wearing a suit.

2. Killua Zoldyck From Hunter x Hunter

Killua Zoldyck From Hunter x Hunter

Killua is introduced as a character who appears similar to Gon: cheeky, cheerful, and full of mischievous ideas. However, contrasting Gon’s politeness, Killua can be quite rude to others, mostly strangers and older people.

He is most commonly known for having a sweet tooth; he loves everything sweet and spent almost 200 million on snacks when he was at the Heavens Arena.

He is also one of the quickest-thinking characters and often analyzes a situation with great ease and accuracy. In spite of his young age, his way of thinking, knowledge, and pragmatism give him the attitude of an adult.

1. Korosensei From Assassination Classroom

Korosensei From Assassination Classroom

It was revealed that he was raised in an environment “where everybody could easily betray one another to the point that one could only trust oneself”.

Through these hardships, he decided to become an assassin in order to survive. Despite gaining an apprentice, he only saw him as a tool for his goals, which drove the latter to finally betray his master.

However, after meeting Aguri Yukimura, he finally knew what compassion really was–becoming much more kind and compassionate.

According to Aguri, if he was born in a peaceful country, his personality would be “someone a little perverted, with a good head but a few screws loose, petty about small things, and also very stubborn.”
