Far, far away in a fairy-tale city, a magnificent Mask Ball takes place once a year. Hundreds of candles are reflected in the polished parquet floor, gentlemen circle dressed ladies - and there is a mask on each face. Some have the most ordinary one, and some have a magical one - one of those that firmly grows to the skin, but in return bestows magic on its owner. Rose and her mentor, the royal alchemist, are looking in this city for the thief of an ancient and very powerful mask. The thief must appear at the famous ball to awaken her magic. But you need to catch the thief before the start of the holiday - otherwise it will be too late.
