Inazuma Eleven (2008)

Season 1: Episode 37

Raimon has a new member, Kogure, who plays pranks on them all the time. Still, they'll need all the help they can get, because of a e-mail that Hitomiko received, saying that Kageyama is back, in a huge submarine-based soccer stadium and that he created the Shin Teikoku. Also he's managed to turn two of Kidou's old teammates, Sakuma Jirou and Genda Koujirou, against him! To worse the situation, Sakuma brings out a forbiden hissatsu, Koutei Penguin No. 1!
