Eyeshield 21 Season 1 Episode 30

The Devil Bats are resting at the Wild Gunmen ranch. The coach has agreed to train them. Hiruma mentions that Deimon does not allow extra-curricular activities after the third year so it’s his and Kurita’s last chance for the Christmas Bowl. That means they must improve in 40 days, not 405 (a year plus 40). Hiruma says the team must do the death march and that he will complete it even if it kills him. On the day the Devil Bats are supposed to return to Japan, the whole team chooses to go through the death march along with Hiruma and Kurita.
