In their first match of the summer tournament, the Mifune Dolphins lost all of the four point lead they had due to Daigo's grave mistake.
Daigo is completely demoralized and depressed about that mistake, when an unexpected voice makes him look up at the fence.
Unbelievably, Hikaru had come there all the way from Gunma!
Slightly awkward, as he left the team behind back then, Hikaru was there without a uniform just to cheer the team on.
But what's that in Hikaru's bag?!
I know what that is. 
I read about it in a book.
