Key of Egg [v1.02]

In a stowed away town, there carried on with a family with a power that can’t be displayed to the world. They lived while securing and passing down the family treasure, the “Key of Egg”.
Be that as it may, a few decades prior, it was taken away, and they presently carry on with lives essentially empty.

The hero Selafina is treated as a princess in this town. However, at some point, a letter shows up addressed to Selafina from Anju, a young lady that contradicted the family stowing away in a town, and got away. “I tracked down the Key of Egg. We should have a contest, and see which one of us can get back with it close by. Assuming I win, I will end up being the genuine princess of the town. In the event that they don’t acknowledge me thusly, the Key of Egg will not be returned.” Upon understanding this, the town seniors, unfit to let an opportunity to recuperate the Key of Egg get away, send Selafina to Anju as mentioned.
It appears to be the Key of Egg is to be sold at a huge sales management firm in the exchanging city of Mirado.
In this large city, what will befall Selafina…?
