Hak (ハク Haku) is one of the main characters in Akatsuki no Yona. He is formerly known as Son Hak (ソン ハク Son Haku), the former General and Chief of the Wind Tribe. He is an adopted grandson of Son Mundok, the adoptive brother of Tae-Yeon, and the childhood friend of Yona and Soo-Won. Throughout the Kingdom of Kouka, he is known as the “Thunder Beast” due to his outstanding fighting techniques and skills.


Hak appearance

Hak is described as a tall, tough-bodied, and attractive young man with sharp blue eyes. He has short messy black hair with bangs hanging below his eyes. He has a well-built frame cultivated from years of training, which tends to make him quite popular with girls. He wears a sleeveless blue overcoat seamed with bluish-black hemlines over a royal blue robe with black collar and sash. He ties black ribbons in a crisscross pattern over the lower half of his sleeves to prevent them from getting in the way when he is fighting. Underneath his robe, he wears black pants and a pair of dark brown boots overlaid with more crisscross-patterned ribbons. Occasionally, he can be seen wearing a sledge hat when he is hiding his identity.[3] He always (apart from sometimes when in disguise) carries his signature weapon, a Chinese glaive-like weapon called a Hsu Quandao, most of the time with its blade draped in a white cloth held by a black strap. 


Hak is a sarcastic, straight-forward young man who strives to protect Yona at all costs. He has been shown to be self-sacrificing, both physically and emotionally, when it comes to her well being, as well as incredibly loyal to those he respects and obeys. Hak has been shown to have a mischevious streak as well, often teasing Yona and the others of his party, as well as a "having a habit" of being a bully who enjoys branding some of their other companions with mocking nicknames, like "White Snake" (Kija) and "Droopy Eyes" (Jae-Ha). Despite this, he is serious whenever it comes to his job. His professionalism extends to a point where he even addresses his childhood friends formally by their status.[4] His devotion to his job stems from his belief in Emperor Il. At first, he had no intention of getting involved with the royal family, as he saw it as troublesome. However, when he witnessed the emperor’s bravery one day, he swore loyalty to them.[5]

Hak, being a naturally loyal person, was the angriest at Soo-won's betrayal for a few reasons. Firstly, Hak was willing to give up his own happiness of being with Yona so that she could marry Soo-Won. Hak would have served under them for the rest of their lives so that they could all remain best friends. The fact that Soo-Won was willing to kill Yona, one of the people he loved most in the world, and destroy her entire future (making both her and Hak fugitives) just for the throne broke Hak's heart. On the very day that Soo-Won killed King Il he also gave Yona a hairpin telling her that her hair was beautiful to encourage her (knowing the fact that she hated her hair at the time). She had just confessed her feelings for him (Soo-Won) and Hak believes that Soo-Won was a very cruel person for doing that to her.

Although in the recent chapters of the manga, Hak for the first time had a monologue where he talks about his feeling towards Soo-Won, demonstrating that Hak doesn't really hate him, but he still doesn't understand why the current king of Kouka acts and his ex-friend would do such a terrible thing. Thus because of everything that had happened it took a long time for Hak to trust anyone especially his teammates when it came to protecting Yona. But as time passed he learned that not everyone will betrayal him like Soo-Won had and came to care about Yona and the Four Dragons, thinking of them as friends. Out of the four dragons, he is close with Jae-ha and Kija despite their different personalities and banter they have seemed to care about one another and will protect each other and their teammates.

When it comes to his heart, Hak destroys his impulses every time they resurface, even though it hurts to do so. There are times that he will show his affection with teasing, but not much beyond that. However, when someone (particularly Jae-Ha) questions the emotional distance between Hak and Yona, Hak loses his composure and can become territorial around the princess. He seems cold around Yona at first, but slowly reveals that he truly cares deeply for her.[6] Hak has been in love with Yona since childhood and never told her about the feelings that he has for her was out of respect of her feelings towards Soo-Won and so because of that he always had a brother-sister relationship with her like teasing at times. Hak gave up his General title and his lively hood in the Wind Tribe just to keep her safe which shows his loyalty, integrity, and devotion to not only Yona but to King Il as well.

Hak, in general, isn't a forgiving person and that is why he finds it so hard for him to understand people like Yona and Jae-Ha who choose not to be swallowed by the impulse for revenge and hatred as well as moving past the hardships they have faced in their lives and he (Hak) wants to be able to do the same. In Chapter 147, as he rescued Jae-Ha and Kija from the Xing soldiers he mentally asks Yona and Jae-Ha how he can move to pass his own hatred for others that are trying to hurt them and for Soo-Won on particular. Despite the fact that Hak has gained better control over his emotions when it comes to seeing Soo-Won face to face he like Yona still suffers from the emotional and mental trauma of the betrayal. In chapter 178 when Keishuk asks them to return to the castle and form an alliance Hak freaked out and basically told Yona that he will never forgive Soo-Won after everything that had happened.


Hak as a child

Hak as a child

Hak was adopted by Mundok at age 2, after losing his parents in the original Xing war.[7] Under Mundok’s guidance, he became one of the strongest members of the Wind Tribe. At some point in time, he became friends with Yona and Soo-Won and whenever he and his grandfather visited the Hiryuu Castle he always played with the two of them.

By the age of thirteen, he was powerful enough to defeat Lee Geun-Tae who was already a general at that time. At fifteen, he became Mundok’s successor and Yona’s exclusive bodyguard. Initially, he was against the idea of being a servant, telling Emperor Il that he wouldn’t be able to take afternoon naps if he were to accept the task. He also deemed the job impossible to be done, due to the emperor’s dislike of weapons. However, when Yona was being assaulted by Kan Tae-Jun, he stopped him and finally accepted the position Emperor Il offered.[8] When he reached fifteen he became the General Commander at the castle. Added to his list of titles is 'Chief of the Wind Tribe' which makes him one very young and accomplished person. At the age of Eighteen, Hak is considered by many to be the greatest Koukan warrior ever to grace a battlefield to the point where even the dragon warriors can agree to this as he is able to keep up with them in battle and fight them head on.


  • Martial Skills: Hak's skills with the Chinese Guandao polearm, or glaive, are the best in the country. His speed and strength allow him to deal powerful blows, even sweeping aside a large area of fog with one swift strike.
  • Swordsmanship: While not his first choice of weapon, Hak is proficient with a sword and ultimately is the one who trains Yona in swordsmanship.
  • Archery: Hak is an excellent shot with a bow, able to shoot bullseyes and birds out out the sky with ease, even on horseback. He is also the person who mostly teaches Yona archery, though Yoon also contributes.
  • Immense Strength: He is noted to have unusual strength by numerous people, including the four dragon warriors.[9][10] Even without his weapon, he can deal strong blows with his fists. Due to his strength and abilities, he was jokingly given the name "Black Dragon", or "Darkness Dragon" by Kija. Despite this, Hak soon was considered as the fifth dragon by the other four dragons. Although not a dragon-blooded warrior, he matches the strength of other dragons easily. Hak is in fact strong enough to catch boulders while sitting comfortably with one hand.
  • Endurance: One of his more defining attributes is his stalwart heartiness, first shown when enduring a bite from a venomous snake when protecting Yona. That being said, this may be mostly due to his determination to live and protect Yona.
  • Basic Medical Skills: Though not as good as Yoon, Hak has shown to have a basic knowledge of medicine. He was able to remove snake poison from his system, and he shows Yona how to remove the thorns and disinfect the cuts she received from the Senjuso test.


  • “A world without weaponry and war, where no one gets hurt, is but a pipe dream.”
  • (To Yona) “Keep your mouth shut and hang on, Princess. I don't care what I have to do. His Majesty is gone now. My master is you. Think of me as a tool. Use me so that you can live! That's what I'm here for!”
  • (To Yona) "The one I like is you, damn it! Don't "eh?" me! I said Ayame has a partner already, I like you, and I don't have a fiancee goddammit! I'm tired out for today! Have you understood everything?! Great! Much better!"
  • (To Hak Yona) "Don't interfere. Before we met you, she did this all the time. When she has enough time, she shoots off as much as 200 arrows in one night. Because I'm here, she doesn't have to do anything. But the princess won't allow herself to be powerless. Her father was killed, and she escaped from the castle. She does this to survive in this world. She's doing whatever she must do. It's not necessarily that I want her to be able to fight, but... I think I also want to see her struggle like a human being."
  • (About Soo-Won) "Amazing... one word from Soo-Won makes the whole town move."
  • (About Soo-Won) "He is a noble. He can also move many different kinds of people. He’s an amazing guy with tons of power… someone like him is looking at me. I need to become someone worthy of your goal. So that from now on, we can walk as equals."
  • (In his head towards Soo-Won) "I felt that you were a guy with such a broad outlook. Differences in position or tribe didn’t matter. You were able to see the world with fair, impartial eyes. In the future, even if I would no longer be able to walk beside you as your equal, that would be fine. Without looking back, only looking forward, I… wanted for you to be King. And then my dream came true in the worst form imaginable."
  • (To himself about Soo-Won ) "This guy genuinely, seriously, might like all people. No, not just all people, all things. And he is interested in them all equally. There are a lot of people I don’t really like, and a lot of things I can’t stand, but… you were looking much further ahead, weren’t you?"
  • (To Yona) “I'm immortal. Actually, I can't afford to die. I've got a troublesome princess to look after.”
  • “When you protect someone you want to keep safe, do you always weigh your own life against theirs?”
  • “When I'm around the princess, I lose my mind.”
  • (To Jae-Ha) "I don't swing that way pal."
  • (To Yona) "I accompanied you, was overwhelmed by your strength and passion, and decided to live for you. The pride of serving someone... the one who taught me that was you!" [11]


  • In the planning phase of Akatsuki no Yona, Hak’s original name was “Soron”. It seemed too similar to “Soo-won”, so it was changed to “Hak-jin”. In the end, it was shortened to “Hak”. The name "Soron" was later re-used as the name of Mundok's deceased biological son.
  • He ranked 1st in the character popularity poll conducted by Hana to Yume in December 2014. He scored 3,001 votes in total.[12] hak is handsome.
  • According to the 2018 fanbook, his parents were casualties of the original Xing war 17 years prior to the start of the plot. He was orphaned at age 2, around the time Yona was born.
  • Hak often refers to himself as the fifth "Darkness" Dragon, in reference to a joke made by Kija that he would be an evil "Darkness Dragon" if he were to be one of the dragons.
  • Hak is considered the strongest warriors in the kingdom. Even some of the dragon warriors are intimidated by his ferocity in battle. For example, Kija thought that Hak's strength could match the strength of his Dragon's hand, and Jae-Ha also believes Hak is very strong.
