It is a faction of Vampire Hunters stationed in Sheng Pei Ren Academy. The main team was made of Yi Shen, Kai Lin, Zhao Yan and Xi Yan.

They guarded the school against Vampires, Zombies and vampire familiars.

When Yi Shen received the Keys of the Forbidden Sphere, and passed it to Zhao Yan, he effectively signed their death warrant, as it was coveted by Fan Le Lao. Yi Sai started going to the school and turned Xi Yan into a vampire at first chance, then made her betray her comrades and her sister.

Yi Shen was killed by Yi Sai's subordinates, Kai Lin was killed by Yi Sai himself, and the sisters were taken by the Sabbat after they eliminated the whole faction.
