^Yea, it is basically the Football Frontier the year after the one from Inazuma Eleven 1.

Btw, where does it say where Saginuma is a 3rd year, it's not on the wiki. Besides, Eisei Gakuen is technically a new school in this timeline since it didn't really exist in the original timeline, so Saginuma's year can't as easily be determined.
