Magical Revolution of the Reincarnated Princess

Despite her supposed ineptitude with regular magic, Princess Annisphia defies the aristocracy's expectations by developing “magicology,” a unique magical theory based on memories from her past life.

That's when Annisphia concocts a plan to help Euphilia regain her good name—which somehow involves them living together and researching magic. Little do these two ladies know, however, that their chance encounter will alter not only their own futures but those of the kingdom...and the entire world.
