Saburo Mitsui is the kicker for the Hakushū Dinosaurs. He is quite stocky in build and has a dark complexion, a square jaw and limp, messy dark hair. When seen, he acts in overall serious manner, never seen smiling and keeps a tight frown.
He is the third best kicker in Kantou but has no further aspirations to gain a higher ranking as he feels Musashi and Koutaro, the two best kickers, cannot be surpassed; this coins his humorous philosophy of "aim for the third place in life".
