Hak (ハク Haku), or Son Hak (ソン・ハク Son Haku) as he was known at the beginning of the story, is the former General and Chief of the Wind Tribe. He is an adopted grand son of Son Mundok, the adoptive brother of Tae-Yeon, and the childhood friend of Yona and Soo-Won. He is known throughout Kouka as the “Thunder Beast” due to his outstanding fighting skills. He helped Yona escape from Hiryuu Castle after Soo-Won killed Emperor Il.
Hak is described as a tall , very sexy 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 and is super popular with girls which makes Yona a bit agitated sometimes.
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.
He always carries his signature weapon, a Glaive, most of the time with its blade draped in a white cloth held by a black strap.
Hak is a mischievous and loyal person who strives to protect Yona at all costs and has been shown to be self-sacrificing, both physically and emotionally, when it comes to her wellbeing. He has a habit of being a bully and likes branding some of the others, like Kija and Jae-Ha, with names. Despite being playful, he is serious whenever it comes to his job. His professionalism extends to a point where he addresses his childhood friends by their status. His devotion to his job stems from his belief in Emperor Il. At first, he had no intention to get involved in the royal family, as he saw it as troublesome. However, when he witnessed the emperor’s bravery, he swore loyalty to them, seeing that he couldn’t leave them alone.
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.
BackgroundEditHak was adopted by Mundok, though the specifics of this event are still unknown. 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 of 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.
When he reached eighteen, 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.
After learning from Soo-Won of murdering Emperor Il, Hak was enraged, attacking Soo-Won in order to protect Yona.
Martial Skills: Hak's skills with the Chinese Guandao polearm 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. Aside from his mastery with a glaive, he is also good in swordsmanship and archery.
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.
Because of his oath to Emperor Il to protect her, he considers himself as a tool for her to use and will practically do anything for her sake. For this reason, he gets scared whenever Yona is reckless and even at one point states that he wants to ‘tie her down’ so that he could stop her. However, at the same time he gets excited to see her finish the risky things she gets herself into because he want to see her act like a normal, non-royal human being, which is something she was unable to do previously, due to of her lifestyle.  Although some may believe he wants to hide Yona, in reality he wants to show her off to everyone, especially the people who chased her out of the castle, and tell them how fine of a princess she is.
In chapter 134, after Yona collapsed, Hak tries to make her feel better about the current situation of the four dragons but it's her who comforts him. He's touched by her attention and hugs her and finally confessing to her while she's in his arm. Unfortunately, Yona only hears "ove you" so she don't get it. When she questions him as to what he said, Hak says "it's nothing" and turns to the other side of the bed, then they end up sleeping under the tent. In the morning, Yona says that she feels like Hak told her something important in her dreams.
Soo-Won and Hak were childhood friends in the past and their friendship seemed unbreakable. Both of them respected each other’s abilities and due to this, Hak trained harder than before so that he can be someone worthy of a goal for Soo-Won –who aspired to be as strong as him– and can equally walk with him someday. As Hak trusted Soo-Won completely, he believed that he could leave Yona to his care, hiding all his feelings for the princess. He even offered himself as his ‘right hand’ if he and Yona ever got married one day, promising that he would support them until he died. However, after Soo-Won killed Emperor Il, their friendship totally collapsed.
Like Yona, he is also inflicted with pain from Soo-Won’s betrayal but didn't outwardly show it to anyone. Deep inside, he is seething with bloodlust and would like to make Soo-Won pay for what he did to Yona and Emperor Il. However, he is also completely saddened by what happened to the three of them and to their relationship that has gone to waste.He also got very angry when he saw Yona still holding on to a hairpin that Soo Won gave her.
At first, Hak thinks of Emperor Il as a 'bubbly' king who is a coward. However, when the emperor stopped Tae-Jun from initiating a fight by grabbing the blade of his sword, he started to respect him and vowed immense loyalty to him and his family. Because Emperor Il was his master, he is guilt-stricken from when he was unable to save him from Soo-Won, even saying that he will regret it for the rest of his life. Throughout the dangers he and Yona faces, he always asks Emperor Il for his guidance, as well as for him not to take Yona away from him.
Hak regards Yoon as a very valuable person on their team. As Yoon provides them with great meals, he rarely gives out insults towards him like he usually does with Yona and the others. Despite Yoon lacking in physical strength, Hak sees him as a very strong person and is able to trust him with looking out for Yona.
Hak forms a rivalry with Kija after the latter asks him to leave Yona’s side as he was no longer needed. His contempt towards him even becomes more complicated when Yona asks Kija to protect him. From then on, he calls him “White Snake” and takes advantage of his entomophobia (fear of bugs). Even with their rocky relationship, Hak considers Kija’s power to be exhilarating as there was no one who fought like him at the castle. They are also able to fight alongside each other perfectly despite offending one another because they share a common goal –to protect Yona.
Though they don't share many interactions, Hak considers Shin-Ah as a capable person. He also thinks that as long as Shin-Ah wears his mask, no one can approach Yona easily. When in need of an alternative clothing to hide his identity, Hak takes Shin-Ah’s fur and puts it over his head. Hak has never given Shin-Ah a nickname, perhaps because he doesn't find him annoying like Droopy-Eyes or White Snake. It is also probable that Hak sees Shin-Ah as a brother.
Much like his relationship with Kija, Hak bullies Jae-Ha on every possible moment and beats him when he flirts with Yona. During their first encounters, Hak found him to be very talkative and piqued his interest about his fixation in freedom. He also quickly deemed him as a pervert, but it got to point where Hak wanted to avoid him as much as possible because he thought that Jae-Ha had a thing for him based on his words and actions (which he clearly misunderstood because of the latter’s double entendre). But when they discovered that Jae-Ha was actually the Ryokuryuu, Hak had no other choice but to become allies with him. Since then, Hak has been constantly forced to show his feelings for Yona due to Jae-Ha's endeavours. Regardless, he considers him to be a good fighter and even admits that it is inconvenient if he’s not around whenever there is a battle and feels at easy sharing with him the responsibilities as the two adults in the group.
Out of all the dragon warriors, Zeno is the one Hak understands the least. At first, he doubted him being the Ouryuu as he appeared frail (despite the said ability of the dragon to be sturdy) and punched Zeno to the face to test if he was the real one. When he had a nightmare where Yona is killed by Soo-Won, Zeno advices him that he shouldn't worry otherwise his life will lessen and nobody would be able to replace him if he dies. Hak thinks the same applies for them dragons warriors, which Zeno appreciates hearing.
- 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”.
