When Avin was entrusted with the task of delivering the Kabessa to Sage Dinerken, Mile was standing guard between Sheep Highway and the entrance to Ourt Village. Mile decides to accompany Avin on his journey, but an extremely dangerous monster called Hamakages prevented both of them from being allowed to leave the village. This monster is wanted by the Adventurer's Guild because of how many people it killed. In order to prove their strength and reliability, Avin and Mile sneaked out of the village and traveled the road in order to slay the monster.
