Masa (マサ) is the eldest of Miyako's older brothers. He is a cabbage farmer who recently landed a contract with a major family restaurant chain. His face is never seen and is only heard talking to Miyako over the telephone. He speaks in a thick Fukuoka accent.
He is implied to be the brother who gives Miyako haircuts and sends her a winter coat far too big for her because he is much taller. Miyako calls him Masa-nii.
