Dark Cores harness the power of Disaster Force, which is explained to be the power born from the distortion of space and time from the summoning portals between the worlds.

Considering that the Hundred Demons are from multiple worlds and have consumed other worlds as well, it wouldn't be surprisng to believe that other people besides Kyoya have harnessed said power and Yamigedo has obtained such capabilities.
