20th Floor

⌊undefined⌋The Twentieth Floor is an important point in the Tower. From this Floor onwards, Regulars are given the right to reside within the Middle Area while taking or retaking their Tests. On the earlier Floors, they likely sleep in dormitories within the Inner Tower. If Regulars give up while climbing the Tower, they have the right to continue residing in the Middle Area either by themselves or with their families. The "ground environment" and "landscape" of the 20th Floor are unknown due to the story setting and Tests that took place on top of an Unidentified Floating Castle.

About
The 20th Floor actually belongs to one of the 10 Great Families. It has one of the symbol. However, since author SIU never explained the detail on what family each of the symbols represents, we can't identify which Great Family owns this floor.

There is a massive increase in the difficulty of Tests on this Floor. Many Regulars go bankrupt paying testing fees needed to retake the test multiple times. Ja Wangnan have some trouble with one of the loan sharks named Kim Lurker for borrowing his money to retake the test after his countless failures. Due to the high difficulty in the tests and small number of Regulars who pass, the 20th Floor is also known as "The needle hole to heaven" and Regulars who pass get recognition and obtain E-Rank Regular status.
