For a long time now, the Capital Kingdom of Regunum has kept its dominance over the land during the raging wars, and kept the world at peace. Recently, however, the appearance of humans who hold within them great mystical power, the "inousha" (literally translated as "a person with a gift/talent"), has caused a disturbance throughout the Kingdom. People have started fearing these inoushas, and have begun to detest them. Because of this, the capital of Regunum has begun to carry out a movement to seize and capture all inoushas within the land to keep the people at bay.

At this time, Ruca, the son of a merchant living in Renugum, discovers that he also holds the same mystical power…
