The series follows the journey of Yona from a clueless, pampered princess to a confident, competent warrior. Joining her are Hak, her bodyguard; Yoon, a healer and chef; Kija, the inheritor of the White Dragon's powers; Shin-ah, the inheritor of the Blue Dragon's powers; Jae-ha, the inheritor of the Green Dragon's powers; and Zeno, the inheritor of the Yellow Dragon's powers.
Sadly, the series ends right after Zeno joins the group, with a clear indication more was intended. There are a couple OVAs which Catman was unable to find.
When you're a Cat, You're a Cat all the way From your first catnip mouse To your ninth dyin' day.
