Ja Wangnan

A young man who repeatedly challenges the 20th Floor E-Rank test but continues to fail, ultimately ending up in debt, calls himself "the man who will become King of the Tower." He possesses a ring engraved with the insignia of Zahard. His combat abilities are average. His emotions are unstable and he often gets discouraged easily, but he essentially has an optimistic and cheerful personality. He dislikes cheating or inhumane actions, but he is prepared to do anything necessary to survive.
