"Hidden "Hidden Floor (숨겨진 숨겨진 층, Sumgyeojin Sumgyeojin Cheung) is another data virtual world hidden somewhere in the Hidden Floor.
The Hidden Floor was first intended as a virtual world within a mirror, created by Zahard in order to preserve the young version of himself from when he cleared the Hell Express. After Zahard become the King of The Tower, many Regulars ended up searching and eventually come into the Hidden Floor. Because of the huge increase in the numbers of newcomers Data Humans in this world, Data Zahard and his companions finally had enough and decided to separate themselves from them, creating their own "private" world, hidden somewhere inside the Hidden Floor. Zahard was helped by an unknown person from the outside who brings another mirror. The two mirrors was faced into each other and the Hidden Hidden Floor was created. After that, Data Zahard transferred to the "Hidden" Hidden Floor with only a few chosen people.
