About
Yu Han Sung is an Advanced Ranker and the former Test Director of the Second Floor who served as the primary antagonist during Part I. He is a legendary figure within the tower, largely due to his decision to decline a High Ranker position. As a key member of FUG, he used his influence to strategically push Viole toward the top of the ranks.
