The legends tells about the four powerful dragon warriors, who are entrusted to protect King Hiryuu and never betray him. But no one expected that there will be a 5th dragon warrior, more or less a woman, who had a relationship with one of the dragon warriors, although it was forbidden. She is the Mauve Dragon. She, like the Yellow Dragon, is believed to be an immortal dragon, although she does not think so. Maybe the reason is something from her past, that does not let her die? Something she does not remember at the moment. Only time will show. As for now, she has a new mission in protecting the descendant of King Hiryuu.... Princess Yona.
