Eyeshield 21: The Ace's Missing?!

SINOPSE

Deimon are up against Amino, a school where they use medical science to increase their muscle sizes. They are all artificial muscles. Sena follows "idiot" Taki onto the wrong bus and ends up to a faraway place, Nagano. Meanwhile Deimon, without their ace, must defeat Amino. At first the Deimon defensive linemen cannot hold Amino back and have a touchdown scored on them. Then Doburoku brings in a truck and tells them to push it until they remember how to push with their hips instead of just their arms, just like during the Death March. Deimon pushes through the line and Monta catches a ball for a first down.
