Beelzebub - Season 1 Episode 46 Burn, Super Combination!

The episode opens with a distinct sci-fi feel, before moving into the game, where the Ishiyama group are in the middle of getting their asses handed to them. They are unable to do anything against the tank. Then Yuka shows up, driving a giant robot called the Crazy Frog. She crushes the tank, and proceeds to kick and tap dance all over the other vehicles. Up until she steps on a mine and loses the tank. Tatsumi's training goes more like an aerobic workout, complete with lame musical accompaniment. He complains about this, calling out for being an exercise, and not training. Meanwhile the gamers run into more trouble when En's team start using an invisibility cheat. Himekawa realizes what they are doing, and goes to prepare some countermeasures. While Tatsumi does pushups, Saotome tells him that Tojo asked to be trained, and if he isn't careful Tatsumi will be overtaken. Saotome uses a recording of Tatsumi's voice to make a training partner who has all his hidden strength.
