During the journey, the boy and his new partner found the mage and his henchmen. A fight happens and the partner is arrested. Yuki runs, but has to face a dilemma: to get a great reward by returning to the Guild to confirm the rumors or help his fellow adventurer and then turn into a hero. Will Yuki be able to give up his interests to help someone he barely knows?
