Medaka Box - Season 1 Episode 11 This Is the End!!

Medaka continues to fight Unzen, gaining the upper hand until she is caught by his reinforced invisible wire and is unable to move, leading Unzen to think he has won. Medaka ends up moving the entire school building in an attempt to continue fighting, though Unzen says that because no reform has taken place, she should consider it her defeat. Just as she is about to deal a final blow, the rest of the Student Council members restrain her and she switches out of War God mode immediately, thanking Unzen and leaving.
