Inazuma Eleven - Season 4 Episode 18 A Visitor

After witnessing Storm Wolf's players turning into aliens and seeing the spaceship in the sky, Inazuma Japan is awestruck to see the players "collected" by the spaceship and an alien called Bitway Ozrock appears in front of them. Bitway informs the team that they were now Earth's representative team, not Japan's, to participate in the Grand Celesta Galaxy. Confused at his words, Gouenji Shuuya suddenly walks into the stadium and explains everything.
