Hyakuya Sect

The Hyakuya Sect was a religious organization at war against the Hiragi family, and they play a prominent role in the prequel series Seraph of the End: Guren Ichinose's Catastrophe at 16. Kureto Hīragi says they were once the most influential group of spellcasters in Japan, and claims they were an even more depraved organization than the Japanese Imperial Demon Army. In particular, they were interested in the "seraph of the end."

The Hyakuya Sect in Japan was believed to have been wiped out by Krul Tepes along with all of their guinea pigs who possessed the seraph gene. However, she saved the children from at least one orphanage and raised them in Sanguinem. Two of the children were seraph. Additionally, a few other seraph children have survived the Apocalypse.

When the Hyakuya Sect was active, it ran orphanages to collect orphaned children. Without fail, they subjected the children to many insane human experiments. They used the children as guinea pigs.
