Natsuko Oozora is Koudai Oozora's wife, and Tsubasa Oozora mother.

Natsuko is in charge of the Oozora residence in Nankatsu City.

Natsuko is a devoted mother —sometimes maybe too cheerful while her children are playing— and takes great care of her older son Tsubasa as a youngster as well as her husband and household. She is greatly understanding with Tsubasa's dream for becoming a pro football player in Brazil.
