The Yurei ghosts had been around for a long time, feeding on human blood and flesh for as long as anyone could remember. Yurei are the ghosts of angels who have been killed and turned into a Yurei themselves, otherwise left to rot.

Yurei feed on the blood and flesh of humans.

In some circumstances, however, they will eat other Yurei as a nutrition source.

Yurei are immortal creatures, regenerating their lost limbs, and only being killed if their heads are cut or a certain part of their body is pierced with a special blade.

Xenra Fujigawa is the name of the Yurei goddess.

The Yurei goddess is said to have special abilities, and more than one ability while most Yurei only possess one. Each Yurei has their own unique ability, with variable forms to use in combat. Every ability is unique and while they may be similar in ways, no two abilities are totally alike.
