The self-proclaimed greatest alchemist in the world, and ruler of the largest Empire ever to grace the continent of Empyrean, Friedrich I, had unlocked the secret to not only creating artificial life forms or homunculi, but also engineering them and augmenting them to perform certain tasks far better than a typical human could.
Naturally, he used this magical science to create an elite, highly skilled, superhumanly strong and magically augmented personal guard unit. Using a secret technique to enhance them and train them, each of these young-looking girls would eventually qualify to take a practical examination in order to earn the feathery wings of an angel in order to become the most elite of the Imperial Guard.
Today was the day of Haia's examination... an adorable young guard who got along well with her creator and her fellow guards and maids who tended to the Imperial Palace. After fueling her up along with her big sisters Saori and Fenna, Friedrich stroked her soft hair and said, "Are we all ready for Haia's test? Go ahead and select your armor and weapons... remember, our enemy is a black dragon. Their breath weapon is acid, and they're resistant to direct damage magic and non-dragonbane weapons. Force multiplier magic should be very useful for the upcoming test, though."
