Sparkling Feather

Long time ago, there was a happy country called the Eternal Feather Kingdom. Protected by benevolent deities, it flourished until a disaster came: a demon destroyed the kingdom, and it disappeared off the face of the earth.

But a few chosen ones, called "Feathers", continued to keep sacred gemstones, which allowed them to use unique powers in the fight against the demonic army.

Each Feather protects a gem, and the protector of the Ruby gem is the protagonist of the game - an ordinary high school boy from our modern world who at first wants nothing to do with ancient prophecies and heroic deeds.
