The Royal Diana Academy is a prestigious school that accepts individuals with adept magical abilities. Upon graduation, these students find themselves at the top of their field or employed by the royal family. Spica Virgo dreams of studying at the academy, aiming to be a top-rate sorceress like her idol Claude Sirius.

Despite the arduous challenges ahead of her, Spica is determined to prove herself as a student worthy of the cat's mentorship. + More
