Miss Shirakawa, as talented as she may be, used to be a fairly ordinary young mage at the Academy of Magic. However, one day her life changed abruptly as a lost human spirit invaded her pet cat Nyanko and fused with its soul into a Magical.
Nyanko used to have a habit of waking miss Shirakawa up in the morning by climbing on her stomach and purring loudly. On the fateful morning, she was woken up not by the cat, but by a young girl with cat ears and a tail instead. Although she first dismissed it as a dream, miss Shirakawa soon realized what had just happened.
As a well-read scholar miss Shirakawa was aware that the law required her to either adopt the newborn Magical as a daughter, or give her away to officials. Although she slightly hesitated at first, Nyanko’s childish frolic and unchanged affection towards her soon awoke miss Shirakawa’s motherly instinct.
Nyanko couldn’t remember almost anything from the previous life of her human part and insisted to keep the same name as the former pet cat. As a newborn Magical, her mental age was determined to be close to a human 5th grader. Soon enough, she started her school life at the Academy’s elementary school.
Years passed and Nyanko entered the senior high school, where she befriended with a red-haired aspiring young mage, Maya. Together they would pull pranks and have little adventures, only to be scolded by miss Shirakawa afterwards. Even after graduating, Nyanko and Maya would actively keep in touch with each other, sharing their funny moments and sometimes even seriously discussing magics.
