Kei “Tsukki” Tsukshima is the angry boy from Haikyu!! He is a first year in Karasuno High School, and joined the volleyball club just because he needed a way to kill time.

He doesn't like hot-tempered guys, nor straightforward ones. Tsukki finds them just too annoying. For as annoying as he finds them, he is one angry boy all the time. He is not one to shout, but he sure knows how to rile people up! He is unkind towards his teammates, and can be very angry at Yamaguchi, who is his only actual close friend. The reason that turned him into a sulky, angry brat was his brother. In fact, he loved his brother, but he was disappointed by him. The lie his brother told him put him in a ridiculous position with his classmates. From that moment onward, he quit being nice and straightforward and turned into a spiteful, angry boy! Okay, he doesn't throw tantrums, but he is a good fit for this list!

In Vampire Knight, the angry-boy part is all up to Zero Kiryuu. Zero is an ex-human vampire, and a vampire hunter who were trained, together with his twin brother Ichiru, by Toga Yagari.

In the beginning, he appears to be very calm and composed. What's more, he is a very kindhearted person. He shows affection toward Yuki Cross, and acts all protective. The situation changes when a shocking truth is revealed: Yuki Cross is a Pureblood vampire. That's the exact moment when Zero turns into a very, very angry boy. He starts to act hostile and cold toward his beloved Yuki. The person he comes to hate the most, though, is Kaname Kuran – supposedly Yuki's brother. The reasons behind his anger are to be found in his past; he was bitten by a vampire, and so his hatred towards vampires developed. That's why discovering that even Yuki – his closest friend and possibly the girl he loves – is a Pureblood vampire is just too much for him to stand!

In Black Butler II, our little villain Alois Trancy is one hell of an angry boy! Alois is the head of the Trancy household, even though he is just a 14-year-old boy. Along with him, there's his demon butler Claude Faustus.

Alois is very sadistic. On the other hand, he can act very cheerful as well. His peculiar trait, though, is the way he can easily switch from a happy-go-lucky character, to a very angry one. He clings to his butler, and tries hard to get his attention, but sadly for the poor boy, Claude is just as apathetic as he seems. Of course, even Alois has his own reasons to be angry. In fact, certain circumstances brought him to be kept as a slave. To make things worse, he had a little brother, who was abused as well, and subsequently, died when the village they were kept in, burnt into ashes. So revenge is the reason why he formed a contract with Claude. Alois has a bad mouth, uses his power in a deliberately vicious manner, and abuses others for his own gratification. Now tell us if he didn't deserve a position in this ranking!

Katsuki Bakugou is a student of the Yuuei Academy, Class 1-A, and one of the main protagonists of My Hero Academia.

Katsuki, as he trains to become a hero, has only one thing in mind: victory. He thinks that the mark of a true hero is to keep on winning. With that in mind, he fights with all he has! He is one angry boy; he is brutal, he keeps bullying Izuku, and while fighting he doesn't care about things around him that end up destroyed. Maybe because when he was a child, thanks to his ability, he was always admired by the other children, and he developed a superiority complex. That's why he just wants to be the best and doesn't like when people look down on him. We all know that an arrogant winner is bound to be alone; for the purpose of being the winner he acts carelessly, is anti-social and doesn't even put an effort to remember his classmate’s names, unless they gave him a reason to. Isn't he angry enough to deserve the 7th place in this ranking?

Rin Matsuoka is one of the main character in Free! He attends the Samezuka High School, and he is a swimmer in the swimming club. His specialty is freestyle and butterfly.

When Rin was a child, his father died. His father's dream was to become an Olympic swimmer, and the fact that he had to give up his dream looked so unfair in little Rin's eyes that he decided to follow his steps. The reasons why he turned out to be an angry boy are probably hidden behind the separation he had to withstand by going all alone to Australia. Before going to Australia, he had joined the Iwatobi swim club, because that club had been his father's starting point and he wanted to create a team to win a relay, just how his father did. When Rin came back from Australia, he probably felt he had lost his place. So while before he swam because he loved swimming, after he came back he just had to win and lost view of his initial goal. So he is just insecure, but tries to hide his fears by being aggressive with everyone, and acting cold toward the others. Above all he is mean towards his ex-teammates who have always admired him instead. The one toward whom he shouts the most, though, is Haruka Nanase. He always felt a strong competition with Haru, so when he discovers that Haru has no intention of taking swimming seriously, he feels betrayed. He just feels as his best rival gave up on him, and that's why he almost ends up hitting him in an outburst of anger!

Emilio Langheim is a 15-year-old boy who happens to be the prince of the kingdom of Endra. He is one angry boy with only a thing on his mind: revenge.

He discovered this shocking truth and while before he was enthusiastic, cheerful and very fond of his uncle, he suddenly turned into a boy full of anger. When his 16th birthday nears, he decides to finally have his revenge. Some circumstances, though, make his plan end up in failure. So he starts a journey with Shun, a boy his equal in age and who fell into Endra by chance, and with the excuse of helping Shun going back to Tokyo, he actually plans his revenge against King Delzain. Emilio is always sulky and can't really relax. He keeps on fighting with Shun, but everyone can see that in the end, they get along just fine. Even though they get along, Emilio maintains his cold attitude toward everyone, and when left alone, he keeps on thinking about the right way to obtain his revenge. Don't you agree with us that this problem kid deserves our 5th position?

Mahiro Fuwa is the very angry protagonist in Blast of Tempest. His mother, his father and his step-sister were killed and in order to find and kill the culprit, he agrees with Hakaze – The magician of Genesis – to stop the resurrection of the Tree of Zetsuen.

With his family destroyed, Mahiro turned out to be very angry. Although he says otherwise, his acts show that he probably was in love with Aika, his step-sister, so when he found her corpse in a pool of blood, he just lost his mind. In an attempt to find the culprit, he doesn't care about the rest of the world, meaning that he doesn't care if it's destroyed or not. He only sees his goal. With high self-esteem, he doesn't even care if people like him or hate him; that's why he vents his anger whenever he feels like it. He doesn't care who his opponent is, he acts violent all the same, even when his opponent is a girl, or when his opponent is clearly weaker than him. He is completely driven by his anger. Basically, focusing solely on his revenge, he doesn't see anything else. The only one who can manage to persuade him is Yoshino, his childhood friend, who was Aika's boyfriend.

Misaki Yata is a member of the HOMRA, the Red Clan organization led by Suou Mikoto. His role in the organization is to act as a vanguard.

Yata is a very angry, hot-tempered boy. First of it all, he always suffered about his height, as he is very small, and he always gets teased by his comrades. Then, he hates his name, as he finds it too feminine. What turned him into a very angry boy, though, aside from his complexes, is probably the fact that his best friend Saruhiko Fushimi, once a member of HOMRA, left the organization and joined the Scepter 4 – the Blue Clan, the police. Yata felt betrayed by his best friend, so the good memories of when Saruhiko was with him in HOMRA now hurt him and make him lose his temper. He is impudent, brutal and shows no mercy towards his enemies. He has a bad mouth and turns out to be very vulgar sometimes; he yells, shouts, and curses openly. Despite his attitude, though, he has a softer side when it comes to Mikoto and the other comrades. In fact, he is very loyal toward HOMRA and he takes his role very seriously.

Valkana is a 25-year-old programmer who joined the tour for Nanakimura Village to start a brand-new life, far away from daily life's struggles. He really is hot-tempered and angry, so much so that it's almost impossible to talk to him without being shouted back at.

Basically, he was a very confident programmer with a brilliant future in front of him. Suddenly, one day, his life turned into a mess. He was fired with a data leaking accusation, but he was actually framed, blamed and kicked out. No wonder he is so angry, as anyone would be. He shows his short temper from his first appearance in the show; when all the participants are asked to do a brief presentation of themselves and start bickering with each other over a trivial matter, he simply jumps up and starts yelling, scaring basically everyone. He just keeps losing his patience seeing how childish and stupid his travel comrades can become, but ironically when push comes to shove, he turns out to be probably the most reliable among the 30 people who joined the tour.

Let's talk about the strongest man in Ikebukuro, Shizuo Heiwajima. Yes, the one who can take a car and send it flying towards his enemy. In spite being a warmonger, he was lucky enough to get a job as a bodyguard – his best friend, Tom Tanaka, hired him.

As he gained our first position, well, we can say he is the angriest among the angry. For as angry as he is, he didn't suffer any trauma in the past to justify his bad temper. Basically, everything started when he was a child and his brother ate his pudding. He got so mad that he tried to lift the refrigerator to throw it at his brother's face. Of course, it ended up in a failure and he was taken to the hospital. After that moment onward, his anger just grew, as well as his strength. So years after, the 23-year-old Shizuo, is able to fight his enemies by lifting and throwing them every kind of heavy object. What is very peculiar about Shizuo is that he actually blames himself for his character; he really suffered when he hurt people who were dear to him, or when he was feared by others during high school. In spite this, though, the anger keeps taking over him and he just have to fight, shout and throw heavy objects.

He wanted to try considering his power as a way to protect, but all his efforts ended up hurting someone in the end. As he gradually became isolated, feared and considered as the representation of violence itself, he came to understand that all he wanted was a place to belong to, and someone who loved him; the realization that it is not possible only manages to make him sad. Ironically enough, he keeps saying that he hates violence. This sentence is just the way he uses to imply that he hates himself, for not being able to be a normal person.
