As the red-headed princess of Kouka, Yona lived the ideal, though sheltered, life within the walls of Hiryuu (Red Dragon) Castle. Doted on by her pacifist and cowardly father, King Il, and protected by her childhood friend/bodyguard, Son Hak of the Wind Tribe, (who has loved her since they were kids, but keeps his feelings in check). She cherishes the time she spends with the "love-of-her-life" (and older cousin), Soo-won. Though, on the night of her 16th birthday, everything changes when she witnessed someone close to her, murder her father. Now on the run, with Hak by her side, she seeks out a legend turned real. Join The Dark Dragon and the Happy, Hungry Bunch (Hak, Yona, Yoon, Kija, Shin-ah, Ao, Jae-ha, and Zeno) on their action-packed, comedic and love-complicated adventure, as they change Kouka from the outside!
