Niinobu Kasamatsu (笠松新信, Kasamatsu Niinobu) is a member of the Taiyō Sphinx. He is the second-largest lineman on the Pyramid Line, though he is more rotund than muscular. He is loud and boastful, and apparently not very intelligent. Against the Deimon Devil Bats, he falls prey to the Devil Bats' shifting block schemes, and is also defeated on two occasions by Kazuki Jumonji while on offense. Like the rest of Taiyō's line, he is severely injured against the Hakushū Dinosaurs.
