Kirona has Tetra fever, a disease that causes her to endure five fevers and cause her death after the fifth. After her second episode, she decides to hide her identity as the princess and heads towards the East, where it is infested with monsters, to find ‘Nadaline’s Flower’. In the middle of Nabimi Forest, the most dangerous part of the monster zone, Kirona rescues a mercenary from Basilisk. She wakes up, tied… “Is it an Eastern tradition to hold a knife at the neck of the benefactor who saved your life?” “Ah, you know. In the East, if you aren’t the killer, you are the killed.” Kirona had taken a liking to Jade Eclipse, the youngest son of the Eclipse family, who was ruined by love.

Where else in the Empire can you find an employer like me?”
