Kang Tae-Jun (カン・テジュン Kan Tejun) is the second son of the Fire Tribe General Kang Soo-Jin. He is in love with Yona and has been determined to make her his wife so he could inherit the throne of the Kouka Kingdom.
Kang Tae-Jun has a light taupe gray hair and brown eyes. He lifts half of his hair into a ponytail, creating a bun shape after it is held by a white and red ribbon. He also accessorizes himself with gold earrings. He dons a maroon sleeved cape with red hemlines and huge white shoulder pads designed with a fire-like shape. Underneath, he has a dark brown robe with gray hemlines and is locked by a brown belt.
Tae-Jun was very carefree and hyper-active as a child. While growing up, he became a fan of books about King Hiryuu and the Four Dragon Warriors. He often wanted to play and grow up as Hakuryuu or fight with dragon claws. However, his hopes were put down by his Kyo-Ga as he told him that the dragons are just legends and that the only person that actually existed was King Hiryuu.
Tae-Jun is a happy, coward, and an arrogant man who is obsessive over Yona. He is a pampered man who gets anything he wants and will grow resentful and childish if someone stops him for claiming it. At times, he can also be sneaky and will go against even to his father's orders if he thinks it'll be for the better. He has a high regard to himself and will boast his position to anyone, especially to those who offended him while he demand to give him an apology. However, despite his high position in the Fire Tribe, he has no idea of the real situation of the villages outside the capital and thinks that the people are merely slacking off.
With his fixation to Yona and getting the throne, he clings to her and will not hesitate to disrespect her if she goes against his wishes. Because of this, he becomes guilt-stricken after he apparently kills Yona on the cliff and grows to be sensitive and unmotivated to live. However, once he sees her again, he drops his egotism and humbles himself down in order to help Yona and eventually, the Fire Tribe itself. He risks himself of getting ill by helping the sick villagers in barren villages, and even one of his men who got ill too despite how badly he wants to go home to Saika. He also starts caring for his soldiers –unlike before where he remains smiling even if they are hurt– and tries to remember each of their names, as well as returning them to their families one day. After experiencing all the citizen’s hardships, his eyes opens to the bad state of his tribe and realizes that with how their current system, there won’t be any future for the Fire Tribe. Along with this, he grows to respect Yona and promises her that he will protect the Fire Tribe for her sake.
Few years before the story, Tae-Jun is shown to be courting Yona. He always sends her flowers and uses sweet words, much to the princess’ annoyance. Though one day, Hak steps between him and Yona to prevent him from assaulting her. Hak tells him that Yona already belongs to him because they have already vowed themselves to each other. He argues over the pair's 'pledges' and attempts to attack Hak, only for Emperor Il to interrupt and to stop him.
After a few years, he is seen once again causing trouble for the Wind Tribe as his father commanded him to. However, after he is scolded for attacking some merchants, he sulks in Saika until a word come that Yona and Hak was seen travelling near the mountains in the border of the Fire and Wind Tribe. Tae-Jun immediately sets up a plan to capture Yona and attack Hak. However, his plans ends the opposite way, and once he thought he has nearly finished Hak off and successfully captures Yona, the princess ends up falling off the cliff.
He then becomes traumatized over his deeds and instantly demands a meeting with Soo-Won. Once he informs Soo-Won what he has done, he tells him he is ready for any type of punishment. But Soo-Won, who held Yona's hair in his hand, could not comprehend her 'death' just yet and neither pick up the ability to think of what to do to Tae-Jun. Kye-Sook immediately decides that Tae-Jun had committed a high act of treason and he needs to be punished. However, Soo-Won thinks otherwise and lets him attend his coronation the day after. Kye-Sook does not argue with his master's decision, but this makes Tae-Jun feeling horrid and he pleads to Soo-Won to punish him rather than do nothing.
Fire Tribe ArcEdit
For the months following the incident of Yona's 'death', he wastes away his days in Saika as he still blames himself for what has happened. His brother kicks him around and tries to snap him out of it, and when nothing seems to work, he gives him the order to capture the thieves currently stealing their taxes or never return to Saika's castle.
While trying to accomplish his mission, he doesn’t seem motivated which makes his subordinates wanting him to go home for his uselessness. When the Hungry Bunch finally shows themselves in Katan Village, he sees this as an opportunity for him to be punished as he thinks that Kija and Jae-Ha are death gods. Seeing Kija’s humongous hands ready to hit him, he welcomes it with open arms but is soon left hanging because the former doesn’t want to stain his sacred dragon hand. Jae-Ha instead attacks him and pins him down on the ground using his dragon foot. He then hears a voice resembling Yona's and with that, he tries to escapes Jae-Ha’s foot until he successfully overcomes it. However, he fails to get a glimpse of her as Kija throws him out of the village.
With him invigorated from a hope, Tae-Jun and his men goes back to Katan Village several times, causing him and his officers to be thrown out of the village again by Kija. Determined to go once again, he disguises himself as a villager and goes alone. Before leaving however, he is given a firework that will signal if the bandits are there. Having fooled Kija that he is a sick villager, he manages to get inside the village. He is then left to Zeno because Yoon isn’t around to treat him. There, he is given a ginger soup by two children as a means of healing him. However, he drops it ‘accidentally’ as he believes that they are trying to poison him. Zeno quickly catches the soup and gives it to the kids. As Zeno explains that it is the only food the children has, Tae-Jun finds it hard to believe. Along in their conversation, Zeno hints that he knows who he is which makes Tae-Jun worry. After that, he hears Yona’s voice again and trails off to find where she is. Because of the cold, Tae-Jun goes to a nearby campfire only to find Hak guarding it. Because of his nervousness, he drops the contents of his bag and the firework gets caught in fire, resulting for it to light up in the sky as it signals his men. He is then quickly caught by Hak. While he is still restrained, he asks if Yona is alive and he doesn’t need to see her as long as long as he knows that she is safe. As the Hungry Bunch gathers around the campfire and Zeno answering his question, he finally sees Yona and cries in happiness. With that, he asks them to let him go as he will stop the confusion he caused and swears that he will not tell about Yona. When he is freed, he runs to his soldiers and stops them from firing.
The following days, Tae-Jun continues to visit Yona and he learns the real situation of his tribe. In hopes that Yona will praise him for his deeds, he helps her on her charity work but later started to do it for the sake of his citizens. Zeno gives a prediction to him that someday he will be someone notable to his fellow men, but Tae-Jun says that that is not what he wants to happen. Later on, because of his efforts, Yona tasks him to take care of the Fire Tribe on which he gladly accepts, even if he can no longer return to Saika as he continues to ‘pursue’ them.  As Tae-Jun does so, his brother visits him and questions his motives for doing such a ridiculous job when he is a general's son. He simply replies that he doesn’t want to do it, but because he thinks that it can help their tribe, he does it for everyone.
Tae-Jun gets scolded easily by Soo-Jin, which leads to him sulking easily after the matter. However, even though they are father and son, Tae-Jun doesn’t have a close relationship with him. Soo-Jin has never really had any high hopes for Tae-Jun because he believes that Kyo-Ga will most likely do all the work. With this, Tae-Jun grew up doing everything he pleases in his own way and was left uneducated on the importance of keeping the Fire Tribe great and thriving even though he is a general's son.
Tae-Jun loves Yona, however, the way he expresses his feelings for her made the princess hate him. At first, he openly flirted with her and liked to tease her as Yona fights with strength of a cat. He even grabbed her hair and didn’t care if she got hurt for this or not. After her “death” however, Tae-Jun becomes repentant and wishes that he can return back time to prevent what had happened. When they meet again, Tae-Jun is happy and relive that she is alive. He feels that he can finally atone for his sins and decides to help Yona during her time as a bandit on the Fire Tribe. His habit of clinging to her still remains, but he learns to respect her and eventually, wishes for her to find her happiness.
