The Progenitor Council (上位始祖会 Jōi Shiso-kai?) is a group of high ranking noble vampires from rank sixth to first that are tasked in monitoring the lower rank vampires and it is only these vampires that are able to attend the Council. The Council is led by Urd Geales, a second and the current strongest progenitor. There are a total of nineteen vampires (excluding the First Progenitor Sika Madu and former 2nd Progenitor Saito).
The Progenitor Council's goal is to annihilate the Japanese Imperial Demon Army and to destroy any organization that conducts Human Experimentation. They conduct meetings every once in a while to discuss and decide on important issues like the Human Experimentation or Demon Army issues. The meeting can also be conducted in emergencies, as Ferid Bathory, a low ranking vampire, conducted the meeting when the humans invaded Sanguinem.
The council meetings are held in vampire Progenitors own castles where they contact each other through a video call. The Progenitors only meet in person if they are punishing vampires or dealing with an important matter.
In Krul's location here are at least fourteen screens, two screens shared a design with five X like designs. One of them had an X symbol within the centre. A different design had the letters resembling JD within them. a male sounding voice asks what was that thing when Yu is seen transforming at the battle of Shinjuku. Another states this could be disastrous for them at seeing the destruction wrought on buildings. A member says queen Krul put an end to the human’s experiments when she exterminated the Hyakuya Sect. Towards the end of the meeting one member asks Ferid who is the young boy standing behind him.
