One year has passed since Shiori's death and his meeting with Azalia. Ken continues to train to make himself stronger. Ken, Sakuya, and Kazuki are the three remaining heroes after Shiori dies. They vowed to become stronger so they would never again lose their friends.
Ken and the other heroes feel burdened when they are asked to fight by the emperor of the Adrienne Empire, Galia Adrienne. After Shiori's death, their burden had become heavier. Apart from protecting the Clorius continent and its inhabitants, they must also protect each other.
Right now, Ken and the other two heroes were on the outskirts of the Earth Dragon Desert area. They had come to that place because they had received information that one of the divine races that had wreaked havoc in the empire's territory was there.
