S02E18 — Do it! The Revolution!

In this episode, Kidou and all the other people at Teikoku Academy were revealed to be part of a "resistance", secretely fighting against 5th Sector. This group also included coach Kudou, and returning characters like Hibiki Seigou (who seems to be their leader) and Raimon Souichirou, the former Chief Director of Raimon. Former Inazuma players Ichino and Aoyama seemed to still care deeply about the team, especially since they can now play "real soccer". Later on, they were seen enjoying soccer, which Shindou witnessed.
