Nana is the main character of Stella: Nana and the Magic English Words. She ends up transferring to an overseas school after her parents are reassigned to another country. Since she can hardly speak any English, she cannot make any friends and is always alone. One day, she meets a spirited pink bird named Stella at the school's botanical garden.
Nana is very alone due the fact that she doesn't know how to speak english. She's pretty kindhearted and sociable, as seen when she finds Stella.
