In a continent called the Great Forest, or the Green Continent, mothers feed their newborn babies with a Decoction of Transformations that gives them extraordinary animal abilities. Increased strength, vision in the dark, resistance to cold - these features are not visible, so people often add animal elements to their clothes to show their skills.
Following the assassinations of the King, his firstborn son, known for his unpredictability and recklessness, should take over the Kingdom. Therefore, numerous factions are pressing the pretender's twin sister to fight for the throne - civil war breaks out.
The use of Decoctions of Transformations of animals that took part in the attack on the King was officially forbidden. Under this pretext, people who already possess their powers are forcibly incorporated into the army to fight in a fratricidal war.
Madmen who want to avoid this fate drink more Decoctions of Transformations in order to mask their forbidden, wild nature - such people were called Hidden Beasts...
