Princess Sacrifice ~Kugi Hime Feena no Bouken~

Swords and magic. An age of violence and wonder.
The benevolent gods of old felt abandoned by humans caught up in their own lives.
Thus, gods abandoned humanity. The celestial realm was barren.
Only spirits on the earth remained.

To protect humanity the spirits gave their Powers to maidens of the shrine.

These maidens were known as...
---Sacrificial Princesses---
