A young idealist who had contributed her life to the kingdom army even though she was born from a noble family. However, she became a troubled soldier over the years and ended up taking on a series of easy jobs. Her people, even her sister who admired her the most, were shocked and disappointed to see how Kirna had changed from an idealist to a person who sought a moderate life. It was Bell, a princess beloved by everyone, that reached out to Kirna. Bell noticed her great talent as it was being wasted on strict and traditional surroundings. Bell prepared a position - the commander of the Ministry of Planetary Defense - which was left unoccupied. Kirna, who matured and gained valuable life lessons from wandering place to place, is now finally ready to spread her wings. And from her experiences, her wings were big enough to embrace and protect the whole Kingdom during its turbulent times.
