Eyeshield 21

A kid in a wheelchair who idolizes Sakuraba realizes he's not the ace of Ojo. He sulks at a river until Sena and the others cheer him up. He returns and talks to Sakuraba, who says he won't be the ace until he is better than Shin and that's why he trains so much. The kid offers him a wristband that he asks Sakuraba to wear in the game against Deimon.
