At the newly established Minato International Junior High School, founded by the Head of the Special District Office using his power, there is a clan created by attending mages called 'Magical Activities of Minato Ward Girls'.

'Tanaka Erin' is an ordinary Japanese middle school student born and raised in Japan. However, because her mother is of Irish descent, she looks entirely Western to anyone, but in reality, she is a Japanese girl who cannot even speak English. She was living an ordinary life until entering middle school, but after meeting Riria and Anna for a certain reason, she discovers that she herself is a user of mythical magic long thought lost.

'Anna M. Battenberg' is a noble lady from Vienna, Austria, whose full name is Anna Marie von Battenberg. Ever since her grandfather's time, when he grew disgusted by the family's bad habits, "finding a good match" became the family's top priority. Perhaps because of this, the entire family is on high alert regarding every single detail of Anna's love life, making her exhausted in many ways. She currently lives in a flower shop building set up in Tokyo by the family's retired butler, and somehow, the butler seems to have eyed the Shunin as Anna's future son-in-law.

'Fujiwara Riria' is a lady from a prominent noble family and a mage who possesses the special power to use ancient shrine maiden magic. She transferred to Minato Junior High School for a certain reason, meeting Erin and Anna and enjoying an ordinary school life.
