The Magical Revolution of the Reincarnated Princess and the Genius Young Lady

Princess Anisphia Wynn Palletia, known as Anis, is a princess who dreams of flying despite her kingdom's views on the matter. As she's unable to use magic, she renounces her throne claim and focuses on developing "magicology," combining resources with knowledge from her past life on Earth. Anis' younger brother Algard assumes the throne and is forced into a marriage with Euphyllia Magenta, but instead turns to a commoner girl, causing a public scandal. After a chance encounter, Anis makes Euphyllia her assistant, but there's more to their partnership than meets the eye.
