Ban did not check the Item yet as he felt that something had changed on his body. He looked around looking for anything that could provide him any reflection so that he could observe his body to no avail. 

Ban then recalled that he brought a mirror before after knowing that the Daily Mission's rewards involved changing his body's strength, stamina and endurance, resulting in his muscles to either expand or condense. 

Ban was sixteen years old with a good body form not befitting of someone his age. It was due to the training with his gramps, and was further enhanced after a few days of completing the Daily Missions.
