Namiko Nozaki

The oldest and most mature member of the group, and thus the one who usually winds up playing the Straight Man role. Her friends call her "Namiko-san", and she is on the receiving end of countless height jokes, breast jokes, weight jokes, and age jokes from Noda. Because her friends are so childish, she tends to get treated as the big sister or mom of the group, and is on good terms with Masa, who is the only other calm one in their circle.
