Serafina and Key to the Egg v.1.092

In a village hidden from the eyes of others, a clan lives, fraught with strength that cannot be demonstrated to the world. The meaning of their existence lies in the protection of the ancient relic of the clan - the Demon Key. A few years ago, the "Key" was stolen, and the clan? devoid of the meaning of existence, forced to maintain now meaningless traditions for the sake of traditions.
The main character, Serafina, is chosen as the "Princess of the Key". To receive this title, the girl was prepared from childhood. However, one day the elder receives a letter addressed to Serafina from an old acquaintance - Anzu, who did not agree with the clan's policy of isolation from the outside world, and therefore fled.
"I found the Demon Key. Let's have a competition to see who is worthy to return with it and become the real Key Princess!"

The Elder, unable to miss such a chance, is forced to send the young Serafina to a city called Mirad, where the "Key", according to Anzu's letter, will be put up for auction.
But in this big city... What will happen to Serafina?
