Blackas Shadow Prince

As prince of the Shadow Kingdom, his bond with Leonas stretches from the ancient era of Demon Kings all the way to the present day, a thousand years later. Upon awakening from his millennium-long slumber, he chose to operate under the guise of a black cat—in truth a miniature black wolf—carrying out intelligence gathering and covert missions from the shadows. Despite his formidable mastery of shadow magic, his small and adorable appearance leads students to mistake him for a pet, affectionately dubbing him 'Kurogane Moemaru,' injecting a strong streak of humor into an otherwise serious narrative backdrop.
