About
A Great Family Head is the most highest ranks within the society of the 10 Great Families, being the leader of the family itself and possess total control over everything, from family treasures, creating their own authorities, have their own army and control the Branch Families.

All of them accompanied King Zahard in climbing and conquering the Tower. They are all technically Irregulars, but they are not considered so in the current Tower society. They are regarded as being incredibly powerful and literally being the "Immortal Gods" in the Tower since they made a contract with 100th Floor Administrator to live eternal life. This contract is known as The Immortality Contract.

According to Ha Jinsung, the Great Family Heads are the true reason why the 10 Great Families remain in balance: The 10 Great Families are not all equal in terms of power, with the Ha, Khun, and Arie Families in particular being the Top 3 of the 10 Families, but the overwhelming power of the Family Heads of each Family evens the imbalance caused by the superiority of any particularly strong member of another Family who is not a fellow Family Head.
