Mao is the girl with pink pigtails held by red bows, who defends Japan from the ground by using a plastic tank (the tank was officially named 'White Tiger,' but she refers to it as 'Mi-kun' because when she was little, she had a kitten she called Mi-kun, but it got lost in a river while she was playing near it one day. She re-named the tank that so it seemed it was still there). As revealed in assorted Physical Education scenes, she is a very slow runner. Her physical ability is minimal.
