Soushin no Ars Magna

Once upon a time, the founder of alchemy brought people from a dying world to a new land. In this fertile and harmonious land, where the man-made "Gods of Creation" act as guardians, people lead a peaceful existence.

However, much time has passed, and the "dust" of death has begun to consume Arkaus.
The gods that have gone mad turn into hideous "Gods of misfortune" and begin to devour the world, and the ash demons born from the dust bare their fangs on the living.
Like burnt scraps of paper and worm-eaten clothes, the world finds itself in an age where the earth is eaten away by ashes.

The people, however, were not entirely unprepared.
Alchemists who wished to continue the wonders wrought by its founder gathered at the Academy of Cagliostro, a school that boasts the highest level of wisdom.

Among them is another, a young alchemist who knocks at the doors of the academy with cherished wishes.
