Sakaki, Doburoku

酒奇溝六

Doburoku serves as the coach for Demon and enjoys drinking sake. He fled to the United States later because he owed two million yen to loan sharks after gambling. He planned to scout talented individuals in America to play American football but ended up involved in Beach football. There, he trained the team Too Tattoos, and after enduring his strict training regimens, they improved as players. Now, since the Devil Bats have paid off his debts (through extensive gambling by Hiruma in Las Vegas), he has become the Deimon Devil Bat's coach and personal trainer.
He and Ojo's trainer, Shoji, were teammates on Sengoku University's American football team and were known as "The Twin Japanese Blades." During that period, he played as a tight-end. Back then, both of them participated in the Death March, with Shoji on the offensive line and Doburoku specializing in defense; however, all their other teammates quit during the last 200 or so kilometers of the Death March, and Doburoku overexerted himself pushing the truck, resulting in an unrecoverable injury to his right knee.
Most of the time, he is somewhat afraid of Hiruma and sometimes looks to him for decisions, especially during the Death March. He does have a stubborn streak. When he went to look for Komusubi while he was missing, he thought he sounded so cool that he didn't give up searching for him, even after Komusubi had already been found.
