These OVA episodes sit alongside Princess Yona's search for the four legendary dragon warriors sworn to her bloodline. One installment fills in the childhood of Kija, the White Dragon, in the village that raised him. The two-part Zeno arc follows Zeno, the Yellow Dragon, back to the era of King Hiryuu and the first four dragon warriors who served him. Yona, the warrior Hak, and the rest of the Happy Hungry Bunch anchor the side stories.
