リプルのたまご ～Apprentice magician～

This is the Avenchurin Kingdom.
One day a great accident befell the kingdom.
The beautiful prince Legrand fell into a deep sleep because of the curse of a forbidden magic book.

The day of the prince's succession test is in one hundred days, somehow the curse has to be dispelled before then.

It is written in a legend that in order to dispel the curse you need a special 'magic stone' with great power. That stone is a troublesome thing that chooses the ones who can use it and also needs to be charged up by people it chooses.
