jyumonji ikki , kuroki koji , togano shozo.

three bullies who initially bossed around Sena on their first day at Deimon until joining Hiruma's hit list. When they try to get back at them, they are unexpectedly recruited to become linemen for the football team, eventually sticking with the team to prove their toughness both to their superiors as well as to their opponents. They are notably poor and inexperienced at the game when they start out, but their eagerness to prove themselves makes them train vigorously and prove to be very capable linemen. Their nickname is from their weird habit of expression, with each one of the trio saying "Ha!?", progressively louder in sequence.
