Grace Field House Numbering (Anime)

''This article is about the Anime version of the Grace Field House numbering. For alternate pages referred to by this name, please click any of the icons above.'' The Numbering on the neck is a standard identification procedure for all children that come to the Grace Field House orphanages. Like livestock, they are marked before they reach the farm. These marks are always on the left side of the neck and are always five-digit numbering. Mamas, Sisters, and Grandma like any other adult human in the Hierarchy of the Demons, also have an identifying number.

Understanding and Analysis
At first glance, the numbers appear to be random, except for the fact that they all have five digits. However, when read from right to left the ID Numbers have a clear order with the oldest adults having the lowest ID Numbers and the number getting higher the younger the children are.

All children at Grace Field House have their numbers ending with 94. Isabella, Krone, and Leslie all have their numbers ending with 84. The children are assigned false birthdays to prevent the Mamas and Sisters from knowing which baby is theirs, so the order of the ID Numbers may not accurately reflect their birth order. However, the closer two children are in age, the closer their ID Numbers will be to one another. So even if the ID Numbers do not accurately reflect birth order, it is likely very close to their real birth order.
