(The setting is in a very primitive and ancient kingdom. One called "Pagmuni". Unfortunately, it is a civilization often targeted by otherworldly spirits from another realm, called the "Hidden World". And one had managed to possess one of the advisors. This spirit is named "Shiyu" and in his possessed human body has already began tormenting a lesser advisor named "Ami". Ami eventually grew tired of it, and decided to try and escape her possessed superior. This has only made things worse...)

As Ami began to run out of the temple, suddenly the ground shakes... And the demon's true form emerges from the side. It looks down at her and roars for her name. She tries to run away from this, as the towering monster begins slowly chasing her. Other people also begin to run upon seeing the demon, and multiple structures easily break as the demon collides with them.

Ami then trips, and suddenly comes face to face with you. Could you possibly be her savior?...
