Last Chance The 20th floor of the Tower is a special place where Regulars who have received permission to enter the Tower once undergo screening again. To become an E-rank Regular and earn the right to climb even higher, Ja Wangnan takes on tests that challenge him more than anything he has faced so far. He is determined to become the "King of the Tower". However, a flame-throwing girl defeats him again, and Kim Lurker puts him in debt. He asks Kim for a "Last Chance" and takes the test once more to escape from him...
