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 main hero and 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.
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 (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 mischievious 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 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 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.
After learning from Soo-Won that he had murdered Emperor Il, Hak was enraged, attacking Soo-Won in order to protect Yona. This leads to the beginning of Hak and Yona's journey to fulfil the prophecy...
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.
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. 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" and seen as the fifth dragon by the other four dragons. Although not a dragon blood, he matches the strength of other dragons easily.
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 thorns and disinfect the cuts she received from the Senjuso test.
Because of his oath to King Il to protect her, he considers himself a tool for her to use and will do anything for her sake. For this reason, he fears for Yona's safety whenever she does reckless things, at one point stating that he wants to ‘tie her down’ so that he can stop her. However, he is also excited to see her finish the risky things she gets herself into because he wants to see her struggle like a normal, oridinary human being, which is something she was unable to do previously, due to her lifestyle.  Although some may believe he wants to keep Yona hidden, he in reality wants to show her off to everyone, especially the people who chased her out of the castle, so that he can tell them how fine a princess she has become.
In chapter 134, when they go to Kouka in hopes of negotiating with Su-Won to stop the threat of war, an overly-stressed Yona worries herself to the point of hyperventilation and faints. Later that night in their tent, Hak tries to make her feel better about the current situation of the Four Dragons but is surprised when she comforts him. Touched, Hak embraces her tightly and confesses his feelings for her. Unfortunately, because his voice was muffled, Yona didn't comprehend what he said, only catching the tail-end of it. When she asks Hak to repeat his sentence, he lets go of her, embarrassed for almost spilling his secret. The next morning, Yona wakes up recalling that in her dream Hak had told her something important.
In chapter 137, they're about to split up to find aid to delay the impending war. Seeing Hak's anxious expression, Yona reaches up and pulls Hak into a kiss, leaving shortly thereafter. Hak, having dealt with an unrequited love for years, is unequipped to deal with this new development, and is teased by Ogi-san. He is in turmoil, wondering if the princess had real feelings behind it, but ultimately deciding to push the thoughts aside until after the Xing conflict is resolved.
In chapter 151, it's revealed to Yona through eavesdropping that Hak has a fiance (Ayame) in the Wind Tribe that had been arranged by Mundok during his childhood. This prompts her to decide to tell him he is free to go back to them if he wanted to. Having taken this as an expression that he's no longer needed, Hak becomes visibly upset and distant from Yona, though he does decide to stay regardless. After swift intervention from the others, Yona quickly realizes her mistake and asks him to stay. Annoyed that she'd think he would leave, he tells her he is following her because he wants to and states that his home is among the Happy Hungry Bunch now. Touched by his words, Yona asks him what he plans to do about his fiancee if he's staying. His frustration snaps and he angrily confesses that he loves her, leaving Yona blushing and stunned, but seemingly finally aware of his feelings.
In the past, Soo-Won and Hak were childhood friends and their bond seemed unbreakable. They both respected and greatly admired the other’s abilities. Due to this, Hak trained vigorously so that he could become someone worthy of being a goal for Soo-Won, who aspired to be as strong as Hak, one day wanting them to walk on equal ground. Hak trusted Soo-Won completely, believing that he could leave Yona in his care, and buried his feelings for the princess. He even offered to be his ‘right hand’ on the condition that he and Yona one day married, promising that he would support them until his dying breath. The two were also mentioned to have raised a falcon named Gulfan together . However, their friendship ended the night Soo-Won murdered the King.
Like Yona, Soo-Won's betrayal hurt him worse than any wound of the body, but intially he didn't outwardly show it to anyone. Deep inside, he seethes with bloodlust and wants Soo-Won to pay for what he did to Yona and King Il, believing it to be his job to one day kill him.
When Hak saves the princess from a nest of snakes after she'd gone to look for the hairpin, he gives it to her (having found it earlier), stating that he would never forgive Soo-Won. Because it was given to Yona the night the King was killed, Hak dislikes the hairpin, personally wanting nothing more but to smash it. He believes Yona to still be in love with Soo-Won because she clings to the hairpin.
In Awa when he finds Yona crying on the ground after having had an encounter with Soo-Won, he reprimands himself thinking he had become too complacent for not focusing on what he believed to be the real danger and letting his guard down. Thinking of this, he glares off into the distance, causing Jae-Ha to comment on his "sorrowful bloodlust."
In chapter 91, Hak succumbs to murderous rage when he finally comes face to face with Soo-Won at the end of the water tribe arc, attacking anyone who got in the way in his warpath to reach Soo-Won, even the other dragons. As Jae-Ha and Kija hold him back, Soo-Won and his entourage make their hasty departure, Hak struggling against the two in his desperate need for revenge. He regains his senses when Yona touches his hand and tells him she's okay, freezing Hak in place when he realizes the extent of his actions.
Although Hak despises Soo-Won, it's shown that this stems from how much he cared for his former friend and how he could not fathom that on the day he plotted to kill King Il he gave Yona that hairpin. He stated that on that night, when he saw Soo-Won ready to silence the princess, he was struck with so much grief that he "felt his heart shatter to pieces."
At first, Hak thinks of Emperor Il as a 'bubbly' king who is a coward. In episode 3 when Hak and Mundok were fighting, Hak called Emperor ll "his Royal Chubbyness". However, when the emperor stopped Tae-Jun from initiating a fight by grabbing the blade of his sword, Hak started to respect him and vowed immense loyalty to him and his family. Because Emperor Il was his master, he is guilt-stricken for being 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 face, he always asks Emperor Il for his guidance, as well as for the emperor to not 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 the fact that Yoon is lacking in physical strength, Hak sees him as a very strong person and is able to trust him with looking out for Yona. Like the rest of the Happy Hungry Bunch, he's taken to calling Yoon "mother", in joking reference to his vast talent with household skills.
Hak forms a rivalry with Kija after the latter asks him to leave Yona’s side stating he was no longer needed. His contempt towards Kija even becomes more complicated when Yona asks Kija to protect him. From then on, he calls him “White Snake” and constantly 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 able to fight alongside each other perfectly despite not initially getting along, as they share the common goal of protecting Yona.
Later, their rivalry seems to have mostly faded and they seem to regard each other as friends, though they still good-naturedly bicker from time to time. Kija seems to consider Hak an honorary brother, as he asks Hak to call him "Big Brother"–an offer that Hak promptly refuses, though the exchange still prompts an inner monologue about how grateful Hak is for Kija and the other's in his and Yona's life. Kija seems quite supportive of Yona and Hak's blooming romance, despite his own romantic feelings toward Yona.
Though they don't share many interactions, Hak considers Shin-Ah 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 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 of Shin-ah's more gentle social presence and anxiety. Later, they seem to be quite close, often being shown having casual chats together. Shin-Ah is easily able to tell that Hak is upset following a misunderstanding between him and Yona.
Much like his relationship with Kija, Hak bullies Jae-Ha at every possible moment and smacks him when he flirts with Yona. During their first encounters, Hak found him to be very talkative and piqued his interest due to his fixation on freedom. Hak also quickly deemed him a pervert, when Jae-Ha's attempts to get him to join Gi-gan's pirate crew were understandably mistaken for come-ons. When Jae-ha is revealed to be the Ryokuryuu, Hak become begrudging allies with him, and Jae-Ha immediately takes to teasing Hak relentlessly about his clear affections for Yona. Regardless of initial distaste, he considers Jae-Ha to be a good fighter and even admits that it is inconvenient if he’s not around whenever there is a battle. Hak feels at ease sharing his responsibilities with him.
Later, their relationship grows quite close. Though they still bicker playfully, Hak seems to use Jae-Ha's "Droopy Eyes" name less like an insult, and more like a nickname. Jae-Ha seems to back off on teasing Hak so much about his feelings for Yona as well, ever since learning about Yona's previous affection for Suwon and how hard the betrayal struck him. They are often seen sharing a drink together, and Hak even confides in Jae-Ha about his worries about Yona's hairpin. Hak is the only person Jae-Ha does not use the "-kun" honorific for within the Happy Hungry Bunch, suggesting that he considers Hak his equal in maturity.
Out of all the dragon warriors, Zeno is the one Hak understands the least. At first, he doubted that he was the Ouryuu as he appeared frail (despite the said ability of the dragon to be sturdy) and punched Zeno in the face to test if he was the real one. When he had a nightmare where Yona is killed by Soo-Won, Zeno advises 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 the dragons warriors, which Zeno appreciates hearing. Zeno notes in chapter 123.5 that, much like the rest of the Happy Hungry Bunch, he regards Hak as rather cute.
