Kang Tae-Jun (カン・テジュン Kan Tejun ) is the second son of the Fire 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 Kouka Kingdom in the beginning, however his 'plans' were thwarted by Hak.
Kang Tae-Jun grew with his brother Kang Kyo-Ga.
His father had high hopes for his brother in life and often didn't have many high hopes for him. He was very carefree and hyper-active as a child.
Tae-Jun and his brother grew up reading books in the richer parts of the Fire Tribe about King Hiryuu and the Four Dragon Warriors.
Tae-Jun was a big fan of these books and often wanted to play and grow up as Hakuryuu or fight with dragon claws. However his hopes were put down by his elder brother as he states that the dragons were just legends and that the only person that actually existed was King Hiryuu.
He is a sneaky man who will go against even his father's orders if he thinks it'll be for the better. He managed to corner Yona and Hak while they were on the run and tried to have Hak killed, but instead his over-aggressiveness caused Yona and Hak to slip from a cliff.
Though later on, it is revealed that he actually has a gentle and kind side when he risks himself of getting ill by helping sick and ill villagers in the poorer tribes in the Fire Tribe.
In his childhood, Tae-Jun was a carefree, happy, naive and hyper-active child.
For the months following the incident of Yona's 'death', he wastes away his days in Capitol Saika. Later on, it is revealed that he still blames himself for Yona's 'death' and is in a traumatised state over it. 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 Capitol Saika's castle.
While trying to accomplish his mission, Kija and Jae-Ha step in to stop Tae-Jun and his officers from trying to capture 'the thieves'. Tae-Jun thinks Kija and Jae-Ha are death gods when he sees Kija's giant hand and is prepared to die for his 'sin'. He then hears a voice resembling Yona's. Once he escapes from being pinned down by Jae-Ha, Kija uses his dragon hand to throw Tae-Jun out of the village. Tae-Jun goes back, causing him and his officers to be thrown out of the village again by Kija.
Determined to go once again, he dresses as a villager and goes alone. Having fooled Kija that he was a villager, he finds out that Yona and Hak are actually alive.
Later on, Tae-Jun makes a promise with Yona to protect the poorer Fire Tribes. Tae-Jun does so, and when his brother visits him and questions his motives for doing such a ridiculous job when he is a general's son, he simply replies ''I don't... want to do it either... but if it can help protect the Fire Tribe, even just a little, then I have to do it!.
