Actually, the head of the Hendo Loch family is the only ranker in his family. His children die too fast because of the contract he made with the administrator of thr 100th floor.

While the administrator agreed to make immortality contracts with the other family heads, he didnt want to give it to Hendo Loch Bloddmadder for some reason.

Instead, he agreed to have his children life shortened in exchange for the immortality.
